JavaScript regex not working for PHP

Question

I have a javascript regex

   Value.match(/[A-Za-z0-9\-\,\.\(\)/]/)

This gives me 1 if a string contains alphabets, numbers, hyphen, comma, dot or braces; if any other character is found it gives 0.

When I apply same regex in PHP it is not working. Why?

no code provided along with the powerful description of is not working... do you really expect solid answers?? — charlietfl

You don't need to escape characters inside [] so you can try this /[A-Za-z0-9,.()]/ or even this one /[\w,.()]/ but if you want to check that the string contains only those characters that regex won't do, try:

/^[\w,.()]+$/

I noticed that you also have /. Is that intentional or a mistake, because you don't mention it in the question...

In javascript / is used to mark regexps while you have to put the regex into a string in php. so this might be the main problem. but your answer has a good point. +1

^ Right, that could be the problem too. We need to see php code.

Regex are pretty much the same across languages. I think the best resource is regular-expressions.info. It's language agnostic but it it'll tell you if something differs in other languages.
