Hi,
return (preg_match(/^[a-z0-9]+$/i, $string));
That a-z0-9 is where you can do it. Just add ! or . or ? to the end:
a-z0-9!?.
Also, if you want upper case letters, make sure you add A-Z:
A-Za-z0-9!?.

It's using the case-insensitive switch.

I tried adding a period to the end but a string will a period still
returns
false
function is_alphanumeric($string)
{
return (preg_match(/^[A-Za-z0-9.]+$/i, $string));
}
No it doesn't. It's not allowing spaces, though... Is that the problem?
