<?php class Foo { public function bar() { echo 'a'; } } $foo = new Foo(); foreach ([['bar']] as $test) { $method = $test[0]; $foo->$method(); // displays "a" ==> success } foreach ([['bar']] as $test) { $foo->{$test[0]}(); // Notice "Array to string conversion" followed by // "Function name must be a string" }

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
