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 expected, you are destroing the property. class foo { public $test; public function __construct() { $this->test = 1; } public function __set($a, $b) { print "set: $a\n"; } public function __get($a) { print "get: $a\n"; } } $test = new foo; print $test->test; unset($test->test); // destroy! print "\n"; $test->test = 'new property'; print $test->test; ------ 1 set: test get: test Previous Comments: ------------------------------------------------------------------------ [2008-03-08 10:36:33] aldo at armiento dot com Description: ------------ Magic methods __set, __get, __isset, __unset are triggered also if a member exists if accessing member from a method used in a cURL callback function. From the documentation instead "These methods will only be triggered when your object or inherited object doesn't contain the member or method you're trying to access". Reproduce code: --------------- <?php class Test { public $member; public function __set($sName, $mValue) { echo "__set() called\n"; } public function __get($sName) { echo "__get() called\n"; } public function __isset($sName) { echo "__isset() called\n"; } public function __unset($sName) { echo "__unset() called\n"; } public function headerCallBack($hCurl, $sHeader) { $this->member = 'value'; strtolower($this->member); isset($this->member); unset($this->member); return strlen($sHeader); } public function httpGet() { $hCurl = curl_init(); curl_setopt($hCurl, CURLOPT_URL, 'http://www.php.net/'); curl_setopt($hCurl, CURLOPT_RETURNTRANSFER, true); curl_setopt($hCurl, CURLOPT_HEADERFUNCTION, array($this, 'headerCallBack')); curl_exec($hCurl); } } $C = new Test(); $C->httpGet(); Expected result: ---------------- Nothing. Actual result: -------------- __set() called __get() called __isset() called __unset() called __set() called __get() called __isset() called __unset() called __set() called __get() called __isset() called __unset() called __set() called __get() called __isset() called __unset() called __set() called __get() called __isset() called __unset() called __set() called __get() called __isset() called __unset() called __set() called __get() called __isset() called __unset() called __set() called __get() called __isset() called __unset() called __set() called __get() called __isset() called __unset() called __set() called __get() called __isset() called __unset() called ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44370&edit=1
