note 51113 added to function.isset

in PHP5, if you have <?PHP class Foo { protected $data = array('bar' => null); function __get($p) { if( isset($this->data[$p]) ) return $this->data[$p]; } } ?> and <?PHP $foo = new Foo; echo isset($foo->bar); ?> will always echo 'false'. because the isset() accepts VARIABLES as it parameters, but in this case, $foo->bar is NOT a VARIABLE. it is a VALUE returned from the __get() method of the class Foo. thus the isset($foo->bar) expreesion will always equal 'false'. ---- Manual Page -- http://www.php.net/manual/en/function.isset.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+51113 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+51113&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+51113&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+51113&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+51113&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+51113&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+51113&report=yes Search -- http://master.php.net/manage/user-notes.php
