How can one troubleshoot issues related to extension directory paths not being recognized in PHP?

When extension directory paths are not being recognized in PHP, it could be due to incorrect configuration settings in the php.ini file. To troubleshoot this issue, check the extension_dir setting in php.ini to ensure it points to the correct directory where PHP extensions are located. Additionally, verify that the extensions are properly installed and enabled in the specified directory.

// Check extension directory path in php.ini
echo ini_get('extension_dir');

// If the path is incorrect, set the correct path
ini_set('extension_dir', '/path/to/extensions');

// Verify extensions are loaded
print_r(get_loaded_extensions());
