reg ex help please

[bastienk]

I have the following requirement and am not sure if the regex I have is correct:

if (eregi("^[A-z0-9\.\?\s]$",$_POST['ad_text'])){

where the input string can be alphanumeric and include the period, question mark and spaces. Is the above correct?

TIA

if (eregi("^[A-z0-9\.\?\s]*$",$_POST['ad_text'])){
                          ^

need to tell it to match multiple times...
