Numbers and commas only

[Ben]

I have a script that I want to use if() to check and see if the $string has numbers and commas only. If it has more than numbers it needs to return a message.

E.g:

PHP Code:

if (isnumber($number)) { 
echo "it is a number"; 
} else { 
echo "it is not jsut number"; 
} 


Does anyone know how I can do this?

[Mr. Tech]

Try this:

PHP Code:

<?php
$what = "2,d67";
if (preg_match("/^[0-9,]+$/is", $what, $match )) {
echo "yep";
} else {
echo "nope";
}
?>
