Is it possible to work with a file using the preg_match_all function? if so, how?

Question

PHP

I am making a parser. The site code is downloaded to a file to work with regular expressions, but I don't know how to work with the file through the preg_match_all function. I tried to insert the file itself, but it says that you need to insert a string, not a file.

Answer 1

<?php
$file_content = file_get_contents($file_path);

preg_match_all($pattern, $file_content);
