呼叫时间通过引用已删除 [英] Call-time pass-by-reference has been removed

问题描述

可能重复：

呼叫时间通过引用已弃用

虽然可能记录在互联网上的某个地方，我找不到我的问题的解决方案。自从PHP 5.4更新，传递引用已被删除。

While it may be documented somewhere on the internet, I cannot find a solution to my problem. Since the PHP 5.4 update, pass-by-references have been removed.

现在我对这段代码有一个问题，我希望有人能看到我想要做的事情，以便他们可以帮助我

Now I have a problem with this section of code, and I hope somebody can see what I'm trying to do with it so that they can possibly help me with a solution to overcome my pass-by-reference problem.

以下是有问题的代码：

public function trigger_hooks( $command, &$client, $input ) {
    if( isset( $this->hooks[$command] ) ) {
        foreach( $this->hooks[$command] as $func ) {
            PS3socket::debug( 'Triggering Hook \'' . $func . '\' for \'' . $command . '\'' );
            $continue = call_user_func( $func, &$this, &$client, $input );
            if( $continue === FALSE ) {
                break;
            }
        }
    }
}

。

推荐答案

只有通话时间通过参考被移除。所以改变：

Only call time pass-by-reference is removed. So change:

call_user_func($func, &$this, &$client ...

至此：

call_user_func($func, $this, $client ...

&

&$this should never be needed after PHP4 anyway period.

如果你绝对需要通过引用传递$ client，更新函数（$ func）signature（ function func（& $ client）{）

If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {)
