How can PHP error logs be utilized to troubleshoot issues with saving data to files?

When encountering issues with saving data to files in PHP, one way to troubleshoot is by checking the PHP error logs for any relevant error messages. These logs can provide valuable information on what might be causing the problem, such as file permission issues or syntax errors in the code. By reviewing the error logs, developers can pinpoint the root cause of the issue and make necessary adjustments to resolve it. 

// Enable error logging to a specific file
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');

// Save data to a file
$file = '/path/to/file.txt';
$data = 'Hello, World!';

if (file_put_contents($file, $data) === false) {
    error_log('Failed to save data to file: ' . $file);
}
