Trim White spaces

[web2000]

Hello,

 

I want to trim all white spaces our of a string and also any other characters other than numbers and letters.

 

It is for a domain name script so it needs everything removed other than numbers and letters

 

I have this so far but this only does white space??

 

$text = preg_replace('/\s+/', ' ', $text);

errmm well to totally remove everything other than numbers and text characters so 0-9 and a-z

Try this:

<?php 

$text = "This is a test 1234";

echo preg_replace('/[^a-zA-Z0-9]/','',$text); 

?>

This also work, used the build-in alpha numeric char set

 

ereg_replace("[^[:alnum:]]",'',$str);
