What is the best practice for changing the content of a PHP file, not just the variables within it?

When changing the content of a PHP file, it is best practice to use a file handling function such as file_get_contents() and file_put_contents() to read and write the file content. This ensures that the file is properly opened, read, and written to without causing any issues with file permissions or formatting. 

// Read the content of the PHP file
$filename = 'example.php';
$file_content = file_get_contents($filename);

// Modify the content as needed
$new_content = str_replace('old_content', 'new_content', $file_content);

// Write the modified content back to the PHP file
file_put_contents($filename, $new_content);
