This is an reply to Adam F-K's alphanumeric check:
I guess my function does the same, but a bit quicker
<?php
// Checks, if the String contains only allowed Chars
// edit the RegEx if you need other chars as well
// for example: [^A-Za-zóòöôúùüûéèêáàäâÓÒÖÔÜÚÙÛÁÀÂÄ .-]
// return true or false
function isAlphaNumeric( $str )
{
$len_org = strlen( $str );
$len_chk = strlen( ereg_replace( "[^A-Za-z0-9]", "", $str ) );
return $len_org == $len_chk;
}
?>
