At least your proposed syntax new (func())() isn't quite readable or understandable. ------------------------------------------------------------------------ [2010-05-13 12:53:31] m dot przybylski at bkfmyjnie dot pl Description: ------------ Operator `new' accepts either class name as either symbol token or variable containing class name (T_STRING or T_VARIABLE), but does not allow expressions returning class name. Test script: --------------- /* first form, works */ $handler = new SomeClass($constructorParam); /* second form, works */ $handlerClass = handlerFor($something); /* returns name of some class to be instantiated */ $handler = new $handlerClass($constructorParam); /* third form -- does not work */ $handler = new (handlerFor($something))($constructorParam); Expected result: ---------------- The third form ought to work just like the other two, so one doesn't need to create extra variable for single use. Actual result: -------------- PHP Parse error: syntax error, unexpected '(', expecting T_STRING or T_VARIABLE or '$' ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=51808&edit=1
