PHP 5.3.1的按引用传递问题 [英] Pass by reference problem with PHP 5.3.1

问题描述

好的，这是一个奇怪的问题，所以请按我的解释忍受.

Ok, this is a weird problem, so please bear with me as I explain.

我们将开发服务器从PHP 5.2.5升级到了5.3.1.

We upgraded our dev servers from PHP 5.2.5 to 5.3.1.

切换后加载我们的代码，我们开始收到如下错误:

Loading up our code after the switch, we start getting errors like:

Warning: Parameter 2 to mysqli_stmt::bind_param() expected to be a reference, value given in /home/spot/trunk/system/core/Database.class.php on line 105

提及的行(105)如下:

the line mentioned (105) is as follows:

call_user_func_array(Array($stmt, 'bind_param'), $passArray);

我们将行更改为以下内容:

we changed the line to the following:

call_user_func_array(Array($stmt, 'bind_param'), &$passArray);

在这一点上(因为allow_call_time_pass_reference)已关闭，php抛出了这一点:

at this point (because allow_call_time_pass_reference) is turned off, php throws this:

Deprecated: Call-time pass-by-reference has been deprecated in /home/spot/trunk/system/core/Database.class.php on line 105

尝试修复此问题一段时间后，我崩溃了，将allow_call_time_pass_reference设置为on.

After trying to fix this for some time, I broke down and set allow_call_time_pass_reference to on.

这消除了Deprecated警告，但现在每次有或没有引用时都会抛出Warning: Parameter 2 to mysqli_stmt::bind_param() expected to be a reference警告.

That got rid of the Deprecated warning, but now the Warning: Parameter 2 to mysqli_stmt::bind_param() expected to be a reference warning is throwing every time, with or without the referencing.

我不知道如何解决此问题.如果目标方法是我自己的方法，则只需在func声明中引用传入的var，但这是(相对)本机方法(mysqli).

I have zero clue how to fix this. If the target method was my own, I would just reference the incoming vars in the func declaration, but it's a (relatively) native method (mysqli).

有人经历过吗?我该如何解决?

Has anyone experienced this? How can I get around it?

谢谢.

推荐答案

您正在传递元素数组($ passArray).传递的数组 inside 中的第二项需要作为引用，因为这实际上是您要传递给该函数的项的列表.

You are passing an array of elements ($passArray). The second item inside the passed array needs to be a reference, since that is really the list of items you are passing to the function.
