Quickie on preg_match

Posted by Quaor (Quaor), 22 July 2003

Hi all. Have a very simple question for you - yes I'm a newbie, just can't get this right...
How do I check for the string www using preg_match?

Many thanks

Here is a test using preg_match to see if a string entered by the user contains the letters "www" anywhere in it:

Code:

<form><input name=url></form>
Does a string contain "www"?<br>
<?php
if (preg_match("/www/",$_GET[url])) {

print ("Yes");
} else {
print ("No");
}
?>

The test would differ if you were looking for the string www exactly, or looking only for strings starting with www.
