Ошибка php failed to open stream

There are many reasons why one might run into this error and thus a good checklist of what to check first helps considerably.

Let’s consider that we are troubleshooting the following line:

require "/path/to/file"

Checklist

1. Check the file path for typos

  • either check manually (by visually checking the path)

  • or move whatever is called by require* or include* to its own variable, echo it, copy it, and try accessing it from a terminal:

    $path = "/path/to/file";

echo "Path : $path";

require "$path";

    Then, in a terminal:

    cat <file path pasted>

2. Check that the file path is correct regarding relative vs absolute path considerations

  • if it is starting by a forward slash «/» then it is not referring to the root of your website’s folder (the document root), but to the root of your server.
    • for example, your website’s directory might be /users/tony/htdocs
  • if it is not starting by a forward slash then it is either relying on the include path (see below) or the path is relative. If it is relative, then PHP will calculate relatively to the path of the current working directory.
    • thus, not relative to the path of your web site’s root, or to the file where you are typing
    • for that reason, always use absolute file paths

Best practices :

In order to make your script robust in case you move things around, while still generating an absolute path at runtime, you have 2 options :

  1. use require __DIR__ . "/relative/path/from/current/file". The __DIR__ magic constant returns the directory of the current file.

  2. define a SITE_ROOT constant yourself :

    • at the root of your web site’s directory, create a file, e.g. config.php

    • in config.php, write

      define('SITE_ROOT', __DIR__);

    • in every file where you want to reference the site root folder, include config.php, and then use the SITE_ROOT constant wherever you like :

      require_once __DIR__."/../config.php";
...
require_once SITE_ROOT."/other/file.php";

These 2 practices also make your application more portable because it does not rely on ini settings like the include path.

3. Check your include path

Another way to include files, neither relatively nor purely absolutely, is to rely on the include path. This is often the case for libraries or frameworks such as the Zend framework.

Such an inclusion will look like this :

include "Zend/Mail/Protocol/Imap.php"

In that case, you will want to make sure that the folder where «Zend» is, is part of the include path.

You can check the include path with :

echo get_include_path();

You can add a folder to it with :

set_include_path(get_include_path().":"."/path/to/new/folder");

4. Check that your server has access to that file

It might be that all together, the user running the server process (Apache or PHP) simply doesn’t have permission to read from or write to that file.

To check under what user the server is running you can use posix_getpwuid :

$user = posix_getpwuid(posix_geteuid());

var_dump($user);

To find out the permissions on the file, type the following command in the terminal:

ls -l <path/to/file>

and look at permission symbolic notation

5. Check PHP settings

If none of the above worked, then the issue is probably that some PHP settings forbid it to access that file.

Three settings could be relevant :

  1. open_basedir
    • If this is set PHP won’t be able to access any file outside of the specified directory (not even through a symbolic link).
    • However, the default behavior is for it not to be set in which case there is no restriction
    • This can be checked by either calling phpinfo() or by using ini_get("open_basedir")
    • You can change the setting either by editing your php.ini file or your httpd.conf file
  2. safe mode
    • if this is turned on restrictions might apply. However, this has been removed in PHP 5.4. If you are still on a version that supports safe mode upgrade to a PHP version that is still being supported.
  3. allow_url_fopen and allow_url_include
    • this applies only to including or opening files through a network process such as http:// not when trying to include files on the local file system
    • this can be checked with ini_get("allow_url_include") and set with ini_set("allow_url_include", "1")

Corner cases

If none of the above enabled to diagnose the problem, here are some special situations that could happen :

1. The inclusion of library relying on the include path

It can happen that you include a library, for example, the Zend framework, using a relative or absolute path. For example :

require "/usr/share/php/libzend-framework-php/Zend/Mail/Protocol/Imap.php"

But then you still get the same kind of error.

This could happen because the file that you have (successfully) included, has itself an include statement for another file, and that second include statement assumes that you have added the path of that library to the include path.

For example, the Zend framework file mentioned before could have the following include :

include "Zend/Mail/Protocol/Exception.php"

which is neither an inclusion by relative path, nor by absolute path. It is assuming that the Zend framework directory has been added to the include path.

In such a case, the only practical solution is to add the directory to your include path.

2. SELinux

If you are running Security-Enhanced Linux, then it might be the reason for the problem, by denying access to the file from the server.

To check whether SELinux is enabled on your system, run the sestatus command in a terminal. If the command does not exist, then SELinux is not on your system. If it does exist, then it should tell you whether it is enforced or not.

To check whether SELinux policies are the reason for the problem, you can try turning it off temporarily. However be CAREFUL, since this will disable protection entirely. Do not do this on your production server.

setenforce 0

If you no longer have the problem with SELinux turned off, then this is the root cause.

To solve it, you will have to configure SELinux accordingly.

The following context types will be necessary :

  • httpd_sys_content_t for files that you want your server to be able to read
  • httpd_sys_rw_content_t for files on which you want read and write access
  • httpd_log_t for log files
  • httpd_cache_t for the cache directory

For example, to assign the httpd_sys_content_t context type to your website root directory, run :

semanage fcontext -a -t httpd_sys_content_t "/path/to/root(/.*)?"
restorecon -Rv /path/to/root

If your file is in a home directory, you will also need to turn on the httpd_enable_homedirs boolean :

setsebool -P httpd_enable_homedirs 1

In any case, there could be a variety of reasons why SELinux would deny access to a file, depending on your policies. So you will need to enquire into that. Here is a tutorial specifically on configuring SELinux for a web server.

3. Symfony

If you are using Symfony, and experiencing this error when uploading to a server, then it can be that the app’s cache hasn’t been reset, either because app/cache has been uploaded, or that cache hasn’t been cleared.

You can test and fix this by running the following console command:

cache:clear

4. Non ACSII characters inside Zip file

Apparently, this error can happen also upon calling zip->close() when some files inside the zip have non-ASCII characters in their filename, such as «é».

A potential solution is to wrap the file name in utf8_decode() before creating the target file.

Перенес сайт на новый сервер и после этого отвалилась загрузка файлов. Код в общем стандартный и прежде прекрасно работал (Добавлять пока сюда его не буду)

Выдает «Warning: imagepng(images/upload/1090d639d14df68959c5a1ccb0e47556/logo.png): failed to open stream: Permission denied in /var/www/….»
Пути к файлам проверил. Даже права выставил на 777, но это не помогло. Есть предположение что временный файл пишется не корректно, но как проверить не знаю. Только var_dump($_FILES[«logo»]); но выдает он правильную информацию — и название и вес файла.

Прошу советы что можно еще проверить и какими способами можно проверить источники проблем?

Есть подозрение, что imagepng() пытается писать в такое место, где у него нет прав.
Попробуйте вместо images/upload... указать абсолютный путь. Проверьте еще раз, есть ли права. И не только на корневую папку images, но и на вложенные.

Пригласить эксперта

Permission denied in /var/www/…. это права доступа !
если у вас на локальной машине это и как правило linux hosts то откройте права для чтения и записи

Перечень мер, если появилась ошибка «Не удалось открыть поток: отказано в доступе».
1. Узнайте код ошибки php. Для этого поместите этот код в начало файла php.
ini_set(‘error_reporting’, E_ALL);ini_set(‘display_errors’, 1);ini_set(‘display_startup_errors’, 1);
2. К папке должен быть доступ 777. Проверьте это.
3. Тег должен иметь атрибут enctype = «multipart/form-data» method = «post».
<form enctype="multipart/form-data" method="post">
4. Откройте и посмотрите массив $ _FILES на сервере.
print_r ($_FILES);
5. Откройте и посмотрите массив $ _FILES на клиенте.
file = document.getElementById(«get_avatar»).files[0];parts = file.name.split(‘.’);
var a = file.size;var b = parts.pop();var c = file.type;alert(a+b+c);
6. Проверьте права пользователя и группы пользователей на каталог.
cd /var/www/your_site/user
ls -l

В вашем случае, проверьте права на директорию images/upload/1090d639d14df68959c5a1ccb0e47556, права должны быть 777 и проверьте права пользователя и группы пользователей на этот каталог.

The ‘Failed to Open Stream: No Such File or Directory’ error is a common issue that developers face while working with file system functions in PHP, such as fopen(), file_get_contents(), require(), and include(). This error occurs when the specified file or directory is not found in the given path. In this guide, we will walk you through different solutions to troubleshoot this issue.

Table of Contents

  1. Check File or Directory Path
  2. Verify File Permissions
  3. Use Absolute Path Instead of Relative Path
  4. Check PHP Configuration
  5. FAQ

Check File or Directory Path

One of the most common reasons for the ‘Failed to Open Stream: No Such File or Directory’ error is an incorrect file or directory path. Double-check the path to ensure that you have not made any typographical errors or included any extra characters.

// Incorrect path
require_once('wrong/path/to/file.php');

// Correct path
require_once('correct/path/to/file.php');

Verify File Permissions

If the file or directory path is correct, check if the file or directory has the proper permissions. The file should have read permission for the user running the PHP script. You can use the chmod command to change the permissions of the file.

# Change file permissions to read, write, and execute for the owner
chmod 700 path/to/file.php

For more information about file permissions, visit the official documentation.

Use Absolute Path Instead of Relative Path

Using an absolute path instead of a relative path can help avoid the ‘Failed to Open Stream: No Such File or Directory’ error. You can use the __DIR__ magic constant to get the current directory and build the absolute path from there.

// Using a relative path
require_once('relative/path/to/file.php');

// Using an absolute path
require_once(__DIR__ . '/relative/path/to/file.php');

For more information about magic constants, refer to the official documentation.

Check PHP Configuration

The PHP configuration file (php.ini) may also cause this error if specific settings are incorrect or misconfigured. One such setting is the open_basedir directive, which limits the files that can be opened by PHP to the specified directory tree.

Ensure that the open_basedir directive includes the paths to the required files, or you can disable the directive by commenting it out or setting it to none.

; Disable the open_basedir directive
; open_basedir = "/path/to/allowed/directory"

; Or set it to none
open_basedir = none

For more information about the open_basedir directive, refer to the official documentation.

FAQ

1. How do I check the file permissions of a file or directory?

You can use the ls command with the -l flag to check the file permissions of a file or directory in Unix-based systems, like Linux and macOS.

ls -l path/to/file.php

For Windows, you can check the file permissions by right-clicking the file, selecting ‘Properties’, and navigating to the ‘Security’ tab.

2. How do I change file permissions on Windows?

To change file permissions on Windows, right-click the file, select ‘Properties’, and navigate to the ‘Security’ tab. Click the ‘Edit’ button to modify the permissions for different users and groups.

3. Can I use the file_exists() function to check if a file exists before using require_once() or include()?

Yes, you can use the file_exists() function to check if a file exists before using require_once() or include(). However, this is not recommended, as it may introduce additional overhead and complexity to your code. It’s better to ensure that the required files exist and have the correct permissions during the deployment process.

4. What is the difference between require() and include() in PHP?

The primary difference between require() and include() is the way they handle errors. If the specified file is not found, require() will produce a fatal error and halt the execution of the script. In contrast, include() will only generate a warning, and the script will continue to execute.

5. Can incorrect file permissions cause security issues?

Yes, incorrect file permissions can lead to security issues. For example, if a file has write permissions for everyone, an attacker may be able to modify the file and inject malicious code. It’s essential to set the correct permissions for your files and directories to maintain the security of your application.

Are you seeing the ‘Failed to open stream’ error in WordPress?

This error message usually points to the location of the scripts where the error has occurred. However, it can be quite difficult for beginner users to understand it.

In this article, we will show you how to easily fix the WordPress ‘Failed to open stream’ error.

Failed to open stream error in WordPress

Why Does the Failed to Open Stream Error Occur in WordPress?

Before we try to fix it, it is helpful to understand what causes the ‘Failed to open stream’ error in WordPress.

This error occurs when WordPress is unable to load a file mentioned in the website’s code. When this error occurs, sometimes WordPress will continue loading your website and only show a warning message. Other times, WordPress will show a fatal error and will not load anything else.

The message phrasing will be different depending on where the error occurs in the code and the reason for failure. It will also give you clues about what needs to be fixed.

Typically, this message will look something like this:

Warning: require(/home/website/wp-includes/load.php): failed to open stream: No such file or directory in /home/website/wp-settings.php on line 19

Fatal error: require(): Failed opening required ‘/home/website/wp-includes/load.php’ (include_path=’.:/usr/share/php/:/usr/share/php5/’) in /home/website/wp-settings.php on line 19

Here is another example:

Last Error: 2023-04-04 14:52:13: (2) HTTP Error: Unable to connect: ‘fopen(compress.zlib://https://www.googleapis.com/analytics/v3/management/accounts/~all
/webproperties/~all/profiles?start-index=1): failed to open stream: operation failed’

Having said that, let’s take a look at how to troubleshoot and fix the ‘Failed to open stream’ error in WordPress.

Fixing the Failed to Open Stream Error in WordPress

As we mentioned earlier, the error can be caused by a variety of reasons, and the error message will be different depending on the cause and location of the file that’s causing the error.

In each instance, the ‘Failed to open stream’ message will be followed by a reason. For example, it might say ‘permission denied’, ‘no such file or directory’, ‘operation failed’, and more.

Fixing ‘No Such File or Directory’ Error Message

If the error message contains ‘no such file or directory’, then you need to look in the code to figure out which file is mentioned on that particular line.

If it is a plugin or theme file, then this means that the plugin or theme files were either deleted or not installed correctly.

You will simply need to deactivate and reinstall the theme/plugin in question to fix the error. If it is a plugin, please see our guides on how to deactivate WordPress plugins and how to install a WordPress plugin.

If it is a theme, please see our guides on how to delete a WordPress theme and how to install a WordPress theme.

However, WordPress may also be unable to locate the files because of a missing .htaccess file in your root folder.

In this case, you need to go to the Settings » Permalinks page in your WordPress admin and just click on the ‘Save changes’ button to regenerate the .htaccess file.

Regenerate htaccess file in WordPress

Fixing ‘Permission Denied’ Error Message

If the error message is followed by ‘Permission denied’, then this means that WordPress does not have the right permission to access the file or directory referenced in the code.

To fix this, you need to check WordPress files and directory permissions and correct them if needed.

Fixing ‘Operation Failed’ Error Message

Finally, some WordPress plugins load scripts from third-party sources like Google Analytics, Facebook APIs, Google Maps, and more.

Some of these APIs may require authentication or might have changed the way developers can access them. A failure to authenticate or an incorrect access method will result in WordPress failing to open the required files.

To fix this, you will need to contact the plugin author for support. They should be able to help you fix the error.
