RE: [PHP] Re: while loop on an array

You don't need to know when you hit the end. Rather, simply remove the last || after the completion of the loop. while (list($new_qID,$new_aID) = each ($new_answers)) { $sql .= "qID=\"$new_qID || \""; } $sql .= substr( $sql, 0, -3) .") AND uID = \"$uID\""; -----Original Message----- "Joe Rice" <jrice@bigidea.com> wrote in message news:20020123091728.A6274@bigidea.com... > > Hello, > > I would like to know how i can know when i'm at the > end of an array during a while loop? > > reset($new_answers); > while (list($new_qID,$new_aID) = each ($new_answers)) { > $sql .= "qID=\"$new_qID\ ||" "; > } > $sql .= ") AND uID = \"$uID\""; > > i would like to know how to stop putting the " || " at > the end of $sql in the middle of the while loop. > > any help would be appreciated. > > thanks, > joe > > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
