note 74230 added to function.property-exists

Something interesting that I've run into that I don't see discussed on here. property_exists doesn't like being called with $this inside of a static method. <? // base class from which all inherit (for laziness) abstract class object { // static so it's not overwritten public static function setMember($member,$value){ if(property_exists($this,$member)){ // doesn't like $this $this->$member = $value; }else{ die("$member is not a property in ".get_class($this)."<br>"); return(false); } } } // extend it with a basic test class class test extends object{ protected $test1; protected $test2; } ?> then <? $test = new test(); $test->setMember('test1',1); /* dies here with: Warning: First parameter must either be an object or the name of an existing class Pointing to the property_exists call */ ?> Another thing: property_exists returns false when called on a private member using $this as the object. ie: <? abstract class object { // not static this time public function setMember($member,$value){ if(property_exists($this,$member)){ // trouble with $this $this->$member = $value; }else{ echo("$member is not a property in ".get_class($this)."<br>"); return(false); } } } // extend it with a basic test class class test extends object{ private $test1; // private will cause false with $this protected $test2; // protected works as expected } $test = new test(); $test->setMember('test1',1); // fails $test->setMember('test2',2); // succeeds ?> ---- Server IP: 69.39.81.135 Probable Submitter: 128.175.51.191 ---- Manual Page -- http://www.php.net/manual/en/function.property-exists.php Edit -- https://master.php.net/note/edit/74230 Del: integrated -- https://master.php.net/note/delete/74230/integrated Del: useless -- https://master.php.net/note/delete/74230/useless Del: bad code -- https://master.php.net/note/delete/74230/bad+code Del: spam -- https://master.php.net/note/delete/74230/spam Del: non-english -- https://master.php.net/note/delete/74230/non-english Del: in docs -- https://master.php.net/note/delete/74230/in+docs Del: other reasons-- https://master.php.net/note/delete/74230 Reject -- https://master.php.net/note/reject/74230 Search -- https://master.php.net/manage/user-notes.php
