How can PHP functions like copy() be used to handle file operations when safe_mode is enabled?

When safe_mode is enabled in PHP, certain functions like copy() may be restricted in their ability to perform file operations. To handle this issue, you can use the ini_set() function to temporarily disable safe_mode before calling the copy() function, and then re-enable safe_mode afterwards. This allows you to bypass the restrictions imposed by safe_mode while still maintaining the overall security of your application. 

// Disable safe_mode temporarily
ini_set('safe_mode', 0);

// Perform file operation using copy()
$source = 'source_file.txt';
$destination = 'destination_file.txt';
if (copy($source, $destination)) {
    echo 'File copied successfully';
} else {
    echo 'Failed to copy file';
}

// Re-enable safe_mode
ini_set('safe_mode', 1);
