RE: More accurate registration

You can allow them only to use alphanumerical characters. You can use regular expressions to validate the user name..

To accept only alphanumerical character the regular expression would be..

php Code:

Original - php Code
$usname="Nazly"; if(eregi("^[a-z0-9]+$",$usname))echo "Valid"; else echo "Invalid";

 
$usname="Nazly";
if(eregi("^[a-z0-9]+$",$usname))echo "Valid";
else echo "Invalid";
