How can one effectively utilize error log files from both PHP and Apache to diagnose and resolve issues related to file operations in PHP scripts on a web server?

To effectively utilize error log files from both PHP and Apache to diagnose and resolve issues related to file operations in PHP scripts on a web server, you should first check the PHP error log for any specific error messages related to file operations. You can also check the Apache error log for any server-level issues that may be impacting file operations. By analyzing these logs, you can identify the root cause of the problem and make the necessary adjustments to your PHP scripts to resolve the issue. 

<?php
// Example code snippet to handle file operations and log errors
$file = 'example.txt';

// Check if the file exists before attempting to read or write to it
if (file_exists($file)) {
    // Perform file operations here
    $data = file_get_contents($file);
    // Example: file_put_contents($file, 'New data');
} else {
    error_log('File does not exist: ' . $file);
    // Handle the error or log it accordingly
}
?>
