php - 错误控制运算符(operator)不工作

Question

我的问题与此类似 one .然而，error control operator对我不起作用。

使用以下代码:

$this->fp = @fsockopen($this->ip, $this->port, $errno, $errstr, $this->timeout);

我仍然收到一条错误消息:
fsockopen(): unable to connect to xxx.xxx.xxx.xx:xxxxx (A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. )
我可以禁用错误控制运算符吗？

我发现了问题!我一直在使用我自己的错误处理程序

set_error_handler('my_error_handler');

如果 @，它会打印出错误而不管是否有前缀。

仅供引用 - 来自 php manual 的代码演示了如何在用户定义的错误处理程序中抑制错误:

// if error has been supressed with an @
if (error_reporting() == 0) {
    return;
}
