#43752 [Com]: PDO bindParam Mangles bound objects

ID: 43752 Comment by: mjs at beebo dot org Reported By: motoma at gmail dot com Status: Open Bug Type: PDO related Operating System: Windows PHP Version: 5.2CVS-2008-01-04 (snap) New Comment: Does the mangling happen without the ATTR_PERSISTENT? It looks like this may be related to: http://bugs.php.net/bug.php?id=43831 which concerns $this getting mangled Previous Comments: ------------------------------------------------------------------------ [2008-01-04 18:32:58] motoma at gmail dot com Description: ------------ I built a class with a __toString() member function. When I pass an instance of this class to bindParam(), the object is overwritten with the result of __toString(). The result from the code sample suggests that bindParam is overwriting the value of the object with the object's __toString() value. Reproduce code: --------------- <?php class test { private $a = 1; public function __toString() { return strval($this->a); } } $db = new PDO('mysql:host=localhost;dbname=test', 'root', '', array(PDO::ATTR_PERSISTENT => true)); $obj = new test(); $prepared = $db->prepare('SELECT * FROM table1 WHERE 1 = :test'); var_dump($obj); $prepared->bindParam('test', $obj); var_dump($obj); ?> Expected result: ---------------- object(test)#2 (1) { ["a:private"]=> int(1) } object(test)#2 (1) { ["a:private"]=> int(1) } Actual result: -------------- object(test)#2 (1) { ["a:private"]=> int(1) } string(1) "1" ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43752&edit=1
