PHP Startup Error: Why Can't PHP Load My Dynamic Library?

PHP Warning: PHP Startup: Unable to Load Dynamic Library

This error message indicates an issue with loading a specific dynamic library when PHP starts up. It usually occurs when an extension is configured to load but the corresponding library cannot be found or accessed.

Explanation

In particular, the error "PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20090626/ixed.5.2.lin'" means that PHP is attempting to load the "ixed.5.2.lin" extension from the specified location, but the file does not exist or PHP is unable to open it.

Causes

This error can have several possible causes, including:

• The extension is not installed or not installed in the correct location.
• The configuration file (usually php.ini) contains an incorrect or outdated path to the extension library.
• The system path is not set up correctly to find the library.
• There is an issue with the permissions on the library file.

Solutions

To resolve this issue, follow these steps:

1. Locate the problematic configuration file: Use phpinfo() or check your PHP configuration files (typically named php.ini) to find the line that specifies where PHP is trying to load the "ixed.5.2.lin" extension.
2. Verify the library path: Ensure that the directory and file specified in the configuration file exist and are accessible by the web server.
3. Correct the configuration: If the path is incorrect, update the configuration file with the correct location of the library.
4. Check permissions: Make sure that the library file has the appropriate permissions for PHP to access it (usually 755).
5. Restart PHP: Once you have made the necessary changes to the configuration file, restart the PHP server to activate them.
