ereg

[sue]

I am trying to use the ereg function to allow only alpha numeric characters and spaces, and I have found the expression
^{[a-zA-Z0-9\s]+$} which works on the site where I found it, but not on my server. Thus the expression Jon Smith is valid on the site where I found the expression but invalid on mine - the space seems to be the problem and no matter what I do I cannot allow a space in my alphanumeric string, which I need to do.
Help Please?

try

<?
$test = "Jon Smith";
if (ereg("^[a-zA-Z0-9 ]+$", $test)) echo "true";
?>

works for me...

Many thanks. So simple and it works on my site. Still baffled about why the \s worked on a test site and not mione, but at least I have a working solution, so thanks once again.
