ReflectionFunction::invoke — Invokes function
argsThe 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.
示例 #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
注意:
ReflectionFunction::invoke() cannot be used when reference parameters are expected. ReflectionFunction::invokeArgs() has to be used instead (passing references in the argument list).
