We can use the instanceof operator using variables: i.e. $objectType = 'StdClass' $this instanceof $objectType works flawlessly! But in order to prevent introducing a variable needed just because of the check i would have guessed i could be able to do: $this instanceof get_class($this) (ofcourse the actual usage would be something else, this is just to illustrate the usage of a function to retrieve some type of class name) Test script: --------------- class Foo { function getClass() { return __CLASS__; } } $bar = new Foo(); var_dump($bar instanceof $bar->getClass()); exit; Expected result: ---------------- true Actual result: -------------- Parse error: syntax error, unexpected '(' ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62089&edit=1
