Honestly, I am horrible with regular expressions and I needed a ton of help making this PHP regex. Although, I have decided that I need to convert a ton of my code to Javascript.

Here is my PHP regex:

if(preg_match('/^(([^,]+,){4}[^,]+\n){3}$/', $all_questions))

Could someone give me a hand on converting it to a Javascript regex?

Greatly appreciated, thanks!

Regex is common in all language. Not specific. –  Praveen Aug 24 '13 at 11:44

@user1671639 No, it’s not. Furthermore, there are quite some significant differences between the various implementations. –  Gumbo Aug 24 '13 at 11:46
    
@user1671639 Not really. It depends on Regex parser language/technology uses. There're different implementations and they differ slightly but unless you use some advanced features, it isn't noticeable. –  Leri Aug 24 '13 at 11:47
    
Although there are differences between regular expression flavors, the one you are using can be used as is in Javascript without the need for any modification. –  Ibrahim R. Najjar Aug 24 '13 at 11:49
    
@Gumbo, Leri Oh Thank you so much for the pointers. I thought that regex expression tend to be same in all languages. –  Praveen Aug 24 '13 at 11:53

In JS, you can do it simple do a .test() with Regex(no need to change the expression). 

var yourRegEx=/^(([^,]+,){4}[^,]+\n){3}$/;
if(yourRegEx.test($all_questions) {  // replace $all_questions with your
                                     // js variable
}

That is an error since $all_questions is a PHP variable –  Fizzix Aug 24 '13 at 11:53
    
@fizzix you want to test it with a PHP variable? or you have a equivalent js variable for that? –  Praveen Aug 24 '13 at 11:55
    
It is still returning an error what I cant the variable to fullString which is my JS variable name. –  Fizzix Aug 24 '13 at 12:04
    
@fizzix yourRegEx.test('<?= $all_questions; ?>') –  Leri Aug 24 '13 at 12:07
    
@Leri - I won't be using that PHP variable anymore. So it would be if(yourRegEx.test(fullString)){alert("Working")} –  Fizzix Aug 24 '13 at 12:12
