Identify a URL Using Regular Expressions

Question

Possible Duplicates:
Checking for a valid url using Javascript Regular Expressions
PHP validation/regex for URL

I have a if statement that will check if the user entered a URL(HTTP Protocol only), like this:

if(/^regexp/.test(url))

But how should be this regular expression to check if the text is a URL or not?

This has been asked lots of times. See http://stackoverflow.com/questions/206059/php-validation-regex-for-url for example. — Coquelicot, Jan 31 '11 at 19:02

I believe this little function might help:

function isURL(string){
  regEx = /(\b(https?|ftp):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/gim;
  return regEx.test(string));
}

Let us know if it worked out!
