Is it possible to change file permissions (chmod) online for PHP files?

Yes, it is possible to change file permissions (chmod) online for PHP files using the `chmod` function in PHP. This function allows you to change the permissions of a file or directory to read, write, and execute. You can specify the permissions using octal values like 0644 for read and write permissions for the owner and read permissions for others.

// Set the file path
$file = 'example.php';

// Set the desired permissions
$permissions = 0644;

// Change the file permissions
if (chmod($file, $permissions)) {
    echo "File permissions changed successfully.";
} else {
    echo "Failed to change file permissions.";
}
