RE: [PHP-DB] Re: while...if statements???

and i always thought the best tactic was to go ugly early. seriously, this isn't really that ugly a solution, most textbooks tend to tell you to use this method to start with as its a bit simpler to understand for beginners - an if...else statement to see if an initial row is returned, then you can happily use a do...while on that first row, and it'll carry on outputting the following rows if there are any more. -----Original Message----- From: Chris Lee [mailto:lee@mediawaveonline.com] Sent: 18 December 2001 20:49 To: php-general@lists.php.net; php-db@lists.php.net Subject: [PHP-DB] Re: while...if statements??? because the while() statement works like this - do something while x is true. if x is not true dont do anything. - do something while conent is in the db. if there is no conent in the db dont do anything. your if() statement is never run if there is no content. $return = mysql_fetch_row($result); if ( isset($return['pet_name']) ) do { echo $return['pet_name'] ."<br>"; } while( $return = mysql_fetch_row($result) ); else echo " No Pets <br>"; its ugly but it works. I dont like ugly, so I wrote my own db wrappers. http://www.mediawaveonline.com/examples/ foreach( $db->select_array('', 'petinfo', '') as $pos => $val ) echo $val['pet_name'] ."<br>"; if ( !isset($val['pet_name']) ) echo " No Pets <br>"; I like that more. but whatever. -- Chris Lee lee@mediawaveonline.com "Jay Fitzgerald" <jayfitz@bayou.com> wrote in message news:5.1.0.14.2.20011218135212.014b4f30@mail.bayou.com... > Does anyone know why this isn't working??
