How can PHP users troubleshoot the "chmod(): Operation not permitted" error when trying to use chmod() in a script?

The "chmod(): Operation not permitted" error occurs when the PHP script does not have the necessary permissions to change the file permissions. To solve this issue, you can try running the script with elevated permissions or changing the ownership of the file to the user running the script. 

// Change file permissions using PHP
$file = 'example.txt';
$permissions = 0644; // Set the desired permissions

if (chmod($file, $permissions)) {
    echo "File permissions changed successfully!";
} else {
    echo "Error changing file permissions.";
}
