how to removing illegal characters?

Hey,

 

How can I remove every character from a string other than 0 to 9?

 

 

Thanks,

Chris

<?php
  $string = "I have values other then 0 45 7 and 432";
  $string = preg_replace('/\D/','',$string);
  echo $string;
?>

 

output:

0457432

<script type="text/javascript">
var re = /\D+/g;
var str = '*+a1b2c3d4e5f6-%';
alert(str.replace(re, ''));
</script>

Considering this is the javascript part of phpfreaks.com, I was hoping to get a response with javascript in it lol

Yeah...I was watching all the forums and missed which one this was actually in.

 

And I know JS too...if only I read more carefully
