erebot / callable-wrapper example snippets


        // Load composer's autoloader
        ebot\CallableWrapper::initialize();

        // Define a function/method that uses the "callable" typehint
        // as you normally would, even for PHP 5.3.x.
        function invokeCode(callable $code) {
            $result = null;
            $code($result);
            return $result;
        }

        // Wrap some code to make it compatible with the typehint.
        // In this case, we used a closure, but you may use anything
        // that is callable by PHP's standards (eg. a function, a method,
        // an anonymous function or an invokable object would be fine too)
        $wrapped = Erebot\CallableWrapper::wrap(
            function (&$retval) {
                $retval = 42;
            }
        );

        // Outputs "int(42)" because the $result from invokeCode()
        // was by reference to the wrapped closure and modified there.
        var_dump(invokeCode($wrapped));
    

        $baseClass = "callable";
        if ($objClass instanceof $baseClass) {
            // ...
        }
