#46624 [Opn->Bgs]: Fetching results using PDO::FETCH_CLASS set attributes before calling ctor

ID: 46624 Updated by: iliaa@php.net Reported By: toby@php.net -Status: Open +Status: Bogus Bug Type: PDO related PHP Version: 5.2.6 New Comment: Thank you for taking the time to write to us, but this is not a bug.

Previous Comments: ------------------------------------------------------------------------ [2008-11-19 20:14:47] toby@php.net Description: ------------ If you set the PDO fetch mode to PDO::FETCH_CLASS and fetch all results from a result set (aka processed statement), the constructor is called after the properties of the newly created object are set. This is incorrect from the OO point of view, since the ctor may provide sensible default values for properties and prepare the object overall. Therefore property manipulation should happen after the ctor was called. Reproduce code: --------------- $db = $this->getTrackbackDbConection(); $select = $db->query( 'SELECT ... ;' ); $select->setFetchMode( PDO::FETCH_CLASS, 'myCustomClass' ); $result = $select->fetchAll(); class myCustomClass { public $someProperty; public function __construct() { $this->someProperty = 'default' } } Expected result: ---------------- myCustomClass->$someProperty is overwritten by a value from the database. Actual result: -------------- myCustomClass->$someProperty is overwritten by 'default' since __construct() is called after the properties have been set in PDO. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46624&edit=1
