finding out if a string contains http:// at the front?

[Adamthenewbie]

I want to find out if a string contains [url]http://[/url] at the front of it. How would I do this?

Thanks

$pattern="/^{http:\/\/[À×]*$/";}

if (preg_match($pattern,$string,$matches)) {
the codes you want to execute.......

here is a good article for this and many more related problems.

Regular expressions? Overkill.

if(substr($string,0,7)=='http://')

even better just snip the [url]http://[/url] out and treat them all the same.
