如何在php中使用数组中的变量参数调用实例变量方法
问题描述：
I want to call a function with variable length arguments stored in an array.
I noticed that you can do this with call_user_func_array($callback, $array);
However it doesn't seem to work on instance variable methods.
class foo{
$iVar
function A{
$anArray = array(...);
call_user_func_array(iVar->methodName,$anArray);
}
}
Any suggestions?

A couple of things are wrong there. First, iVar is not a constant, so it should begin with a $. And since it is a property of foo, it should be $this->iVar.
Secondly, you cannot pass a function like that. You have to pass it as a callable. So in total, the call should look like this:
call_user_func_array(array($this->iVar, 'methodName'), $anArray);
