Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This is an expected behavior and yes it did change from 5.0/5.1 days. An empty object is no longer considered to be "empty". Previous Comments: ------------------------------------------------------------------------ [2007-12-28 11:17:05] packard_bell_nec at hotmail dot com Description: ------------ When I write the codes concerning type conversion, I found the entitled "bug". Then, I check the documentation, and I found the statement "an object with zero member variables (PHP 4 only) is considered FALSE" in~ http://php.net/manual/en/language.types.boolean.php However, I am NOT going to ask for reopening the above "feature". Instead, I am going to ask for correcting the "bug" so that "an object with class stdClass and zero member variables is considered FALSE". The behavior of empty() should also be changed accordingly. The extensions that I used: [PHP_GD2] extension=php_gd2.dll [PHP_MBSTRING] extension=php_mbstring.dll [PHP_MCRYPT] extension=php_mcrypt.dll [PHP_MYSQL] extension=php_mysql.dll [PHP_MYSQLI] extension=php_mysqli.dll [Zend] zend_extension_ts="C:\Program Files\PHP\lib\ZendExtensionManager.dll" zend_extension_manager.optimizer_ts="C:\Program Files\PHP\lib\Optimizer-3.3.0" zend_extension_manager.debug_server_ts="C:\Program Files\PHP\lib\Debugger-5.2.10" Reproduce code: --------------- $foo = null; settype($foo, 'object'); $cv_foo = get_class_vars(get_class($foo)); $ov_foo = get_object_vars($foo); echo gettype($foo).'<br/>'.get_class($foo).'<br/>'.var_export($cv_foo, true).'<br/>'.var_export($ov_foo, true).'<br/>'.isset($foo).'<br/>'.!empty($foo).'<br/>'.var_export($foo, true).'<br/><br/>'; $goo = null; settype($goo, 'array'); echo gettype($goo).'<br/>'.isset($goo).'<br/>'.!empty($goo).'<br/>'.var_export($goo, true).'<br/><br/>'; $hoo = false; settype($hoo, 'object'); $cv_hoo = get_class_vars(get_class($hoo)); $ov_hoo = get_object_vars($hoo); echo gettype($hoo).'<br/>'.get_class($hoo).'<br/>'.var_export($cv_hoo, true).'<br/>'.var_export($ov_hoo, true).'<br/>'.isset($hoo).'<br/>'.!empty($hoo).'<br/>'.var_export($hoo, true).'<br/><br/>'; $joo = false; settype($joo, 'array'); echo gettype($joo).'<br/>'.isset($joo).'<br/>'.!empty($joo).'<br/>'.var_export($joo, true).'<br/><br/>'; Expected result: ---------------- object stdClass array ( ) array ( ) 1 stdClass::__set_state(array( )) array 1 array ( ) object stdClass array ( ) array ( 'scalar' => false, ) 1 1 stdClass::__set_state(array( 'scalar' => false, )) array 1 1 array ( 0 => false, ) Actual result: -------------- object stdClass array ( ) array ( ) 1 1 stdClass::__set_state(array( )) array 1 array ( ) object stdClass array ( ) array ( 'scalar' => false, ) 1 1 stdClass::__set_state(array( 'scalar' => false, )) array 1 1 array ( 0 => false, ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43697&edit=1
