Using array elements to call a method on an object doesn't work in php7, but used to work in php5. I made a simplified example in the test script below. Test script: --------------- <?php class Item { public function save() { echo 'saved'; } } $callback = [new Item(), 'save']; // This works on both php5 and php7 $method = $callback[1]; $callback[0]->$method(); // This works on php5 only $callback[0]->$callback[1](); Expected result: ---------------- Expected "savedsaved" output. Actual result: -------------- saved Notice: Array to string conversion in /var/www/test/array_function.php on line 15 Notice: Undefined property: Item::$Array in /var/www/test/array_function.php on line 15 Fatal error: Function name must be a string in /var/www/test/array_function.php on line 15 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69694&edit=1
