I think this is your solution:
--------------------------------------------------------------------------------
$string = "~YOUR STRING~"
if (!eregi_replace("[0-9A-Za-z -_']","",$string))
{
echo "string allowed";
}
else {
echo "string disallowed";
}
--------------------------------------------------------------------------------
I tested it with the following strings:
$string = "Daniel Anderson"
Returned "string allowed".
$string = "Daniel Anderson!!"
Returned "string disallowed".
$string = "Daniel, yo Anderson"
Returned "string disallowed".
$string = "Daniel_Anderson-Innit"
Returned "string allowed"
I think that may be your solution :)
Hope it helps! Try to keep all the collections like "a-z" within one set of
square brackets.
Warmest Regards,
Dan
