eregi question

[jeffrydell]

This is my first attempt at validating inputs to a form, please be gentle.

 

I want to be sure that no letters are input to a field which should be a phone number.

 

Should this work?  Is there a better way?

 

eregi('a-z', $_REQUEST['phone'])

 

Thanks!

 

Jeff

www.regularexpressions.info I think it is, will show you everything you need to know about "basic" regular expressions (compatible via every major language).

no

try

<?php
$_REQUEST['phone'] = '123-456p';
if (eregi('[a-z]+', $_REQUEST['phone'])) echo 'some leters'; else echo 'no leters';
?>

Thank you - that works exactly as I had hoped.
