Are there best practices for efficiently searching and replacing content between specific markers like %qwe% and %wer% in PHP files?

To efficiently search and replace content between specific markers like %qwe% and %wer% in PHP files, you can use regular expressions with the `preg_replace` function. By defining a pattern that matches the content between the markers, you can easily replace it with the desired content.

$content = file_get_contents('example.php');
$newContent = preg_replace('/%qwe%(.*?)%wer%/s', 'replacement_content', $content);
file_put_contents('example.php', $newContent);
