note 20661 added to ref.strings

Much faster and much better way to check does string consists from alphanumeric chars 'only' ... By the way, author of previous isalphanumstr() forgot to add whitespace to his array. It's not an alphanumeric char, but who would need this function without it ? :) function isalphanumstr($string) { $res=true; for($i = 0; $i < strlen($string); $i++) if((ord($string[$i])<48 && ord($string[$i])!=32) || (ord($string[$i])>57 && ord($string[$i])<65) || (ord($string[$i])>90 && ord($string[$i])<97) || ord($string[$i])>122) {$res=false; break;} return $res; } echo isalphanumstr(" 1234567890qwertyuiopasdfghjklzxcvbnm QWERTYUIOPASDFGHJKLZXCVBNM"); //... returns "1" //;) -- http://www.php.net/manual/en/ref.strings.php http://master.php.net/manage/user-notes.php?action=edit+20661 http://master.php.net/manage/user-notes.php?action=delete+20661 http://master.php.net/manage/user-notes.php?action=reject+20661
