如何从PHP脚本发送500内部服务器错误错误 [英] How to send 500 Internal Server Error error from a PHP script

问题描述

在某些情况下，我需要从PHP脚本发送500 Internal Server Error。脚本应该由第三方应用程序调用。该脚本包含几个 die（this happend）语句，我需要发送 500内部服务器错误响应代码，而不是通常的 200 OK 。第三方脚本将在某些情况下重新发送请求，包括未收到 200 OK 响应代码。

问题的第二部分：我需要像这样设置脚本：

 <？php 
 custom_header（ 500内部服务器错误 ）; 
 $ b $ if（that_happened）{
 die（that happened）
} 
 
 if（something_else_happened）{
 die（something其他发生）
} 
 
 update_database（）; 
 
 //脚本也可以在上面的行中失败
 //例如发生mysql错误
 
 remove_header（500）; 
？> 
  

我只需要在> 200

编辑

一个侧面问题：我可以发送奇怪的500个标题，例如这些：
$ b $ pre $ HTTP / 1.1 500未找到记录
HTTP / 1.1 500脚本生成错误（E_RECORD_NOT_FOUND）
第23行中的HTTP / 1.1 500条件失败


Web服务器是否会记录此类错误？ >

解决方案

  header（$ _ SERVER ['SERVER_PROTOCOL']。'500 Internal Server Error'，true ，500）; 
  

I need to send "500 Internal Server Error" from an PHP script under certain conditions. The script is supposed to be called by a third party app. The script contains a couple of die("this happend") statements for which I need to send the 500 Internal Server Error response code instead of the usual 200 OK. The third party script will re-send the request under certain conditions which include not receiving the 200 OK response code.

Second part of the question: I need to setup my script like this:

<?php
    custom_header( "500 Internal Server Error" );

    if ( that_happened ) {
        die( "that happened" )
    }

    if ( something_else_happened ) {
        die( "something else happened" )
    }

    update_database( );

    // the script can also fail on the above line
    // e.g. a mysql error occurred

    remove_header( "500" );
?>

I need to send 200 header only after the last line has been executed.

Edit

A side question: can I send strange 500 headers such as these:

HTTP/1.1 500 No Record Found
HTTP/1.1 500 Script Generated Error (E_RECORD_NOT_FOUND)
HTTP/1.1 500 Conditions Failed on Line 23

Will such errors get logged by the webserver?

解决方案

header($_SERVER['SERVER_PROTOCOL'] . ' 500 Internal Server Error', true, 500);
