使用register

使用register_shutdown_function（）时，为什么我的'关闭回调'无效？(Why is my 'shutdown callback ' invalid when using register_shutdown_function()?)

警告：register_shutdown_function（）：无效的关闭回调

trait ErrorTrait { public function shutDownFunction() { $error = error_get_last(); // fatal error, E_ERROR === 1 if ($error['type'] === E_ERROR) { //do your stuff $messageStore="Using $this when not in object context"; if (strstr ( $error['message'],$messageStore)) { echo "found it"; } } } public function shutdown_function() { register_shutdown_function('shutDownFunction'); }

}

我在我的主类中使用这个特性并从中调用函数

use ErrorTrait; public function test() { self::shutDownFunction(); self::shutdown_function(); }

然后在这一点上，我在一个名为“run”的函数中调用test中的函数

我所做的只是简单地调用函数。

public function run() { self::test (); // Rest of code}

有关为什么会导致问题的任何想法？

Warning: register_shutdown_function(): Invalid shutdown callback

trait ErrorTrait { public function shutDownFunction() { $error = error_get_last(); // fatal error, E_ERROR === 1 if ($error['type'] === E_ERROR) { //do your stuff $messageStore="Using $this when not in object context"; if (strstr ( $error['message'],$messageStore)) { echo "found it"; } } } public function shutdown_function() { register_shutdown_function('shutDownFunction'); }

}

I use this trait in my main class and call the functions from it

use ErrorTrait; public function test() { self::shutDownFunction(); self::shutdown_function(); }

And then at this point I call the function in test in a function called "run"

All I do is a simply call the function.

public function run() { self::test (); // Rest of code}

Any ideas as to why this is causing problems?

最满意答案

您正在将字符串而不是可调用字符传递给register_shutdown_function 。 电话应该是这样的

register_shutdown_function([$this, 'shutDownFunction']);
You are passing a string instead of a callable into register_shutdown_function. The call should look like
 
register_shutdown_function([$this, 'shutDownFunction']);
