What steps can be taken to troubleshoot PHP scripts that are failing to load modules properly?

If PHP scripts are failing to load modules properly, it may be due to incorrect configuration settings or missing dependencies. To troubleshoot this issue, you can check the PHP configuration file (php.ini) for any errors, ensure that the required modules are installed and enabled, and verify that the correct paths are set for the module files.

// Check PHP configuration settings
echo phpinfo();

// Check if required modules are installed and enabled
if (!extension_loaded('module_name')) {
    echo 'Module not loaded';
}

// Verify module file paths
echo get_include_path();
