(PHP 5, PHP 7)
ReflectionFunction::invoke — Invokes function
...The passed in argument list. It accepts a variable number of arguments which are passed to the function much like call_user_func() is.
Returns the result of the invoked function call.
Example #1 ReflectionFunction::invoke() example
<?php
function title($title, $name)
{
return sprintf("%s. %s\r\n", $title, $name);
}
$function = new ReflectionFunction('title');
echo $function->invoke('Dr', 'Phil');
?>
以上例程会输出：
Dr. Phil
Note:
如果函数有参数需为引用，那么它们必须以引用方式传入。
