Firstly, what is regular expression greed and what is non-greed? Or what is matching priority classifier and what is ignoring priority classifier?
Well, I don’t know what the concept is. Let’s give an example.
One of the students wanted to filter between the content, that is how to write rules and procedures.
$str = preg_replace ('%<script>. +?</script>%i',', $str);//non-greedy
Looks like it’s okay,...
