I have several poisoned .js files on a server. I can use find to recursively find them and then use preg_replace to replace the string. However the string is filled with single quotes, semi-colons and a lot of other special characters. Will preg_relace(escapeshellarg($String),$replacement) work or do I need to go through the entire string and escape what needs to be escaped? --C
First of all, why do you want to use preg_replace when you're not actually using regular expressions??? Use str_replace or stri_replace instead.
Aside from that, escapeshellarg() escapes strings for use in shell execution. Perl Regexps are not shell commands. It's like using mysqli_real_escape_string() to escape arguments for URLs. That doesn't compute, just like your way doesn't either.
If you DO wish to escape arguments for a regular expression, use preg_quote instead, that's what it's there for. But first, reconsider using preg_replace, since I honestly don't think you need it at all if the way you've posted (preg_replace(escapeshellarg($string),$replacement)) is the way you want to use it.
