Interestingly enough, when you use fetchAll, the constructor for your object is called AFTER the properties are assigned. For example: <?php class person { public $name; function __construct() { $this->name = $this->name . " is my name."; } } # set up select from a database here with PDO $obj = $STH->fetchALL(PDO::FETCH_CLASS, 'person'); ?> Will result in ' is my name' being appended to all the name columns. However if you call it slightly differently: <?php $obj = $obj = $STH->fetchAll(PDO::FETCH_CLASS | PDO::FETCH_PROPS_LATE, 'person'); ?> Then the constructor will be called before properties are assigned. I can't find this documented anywhere, so I thought it would be nice to add a note here. ---- Server IP: 208.69.120.55 Probable Submitter: 68.58.70.221 ---- Manual Page -- http://www.php.net/manual/en/pdostatement.fetchall.php Edit -- https://master.php.net/note/edit/97973 Del: integrated -- https://master.php.net/note/delete/97973/integrated Del: useless -- https://master.php.net/note/delete/97973/useless Del: bad code -- https://master.php.net/note/delete/97973/bad+code Del: spam -- https://master.php.net/note/delete/97973/spam Del: non-english -- https://master.php.net/note/delete/97973/non-english Del: in docs -- https://master.php.net/note/delete/97973/in+docs Del: other reasons-- https://master.php.net/note/delete/97973 Reject -- https://master.php.net/note/reject/97973 Search -- https://master.php.net/manage/user-notes.php
