为什么AJAX响应未从PHP返回

发布于 2025-02-08 18:23:00 字数 6280 浏览 2 评论 0原文

我正在尝试通过Ajax取得PHP线程的进度，但是奇怪的是我现在面对的是， startpool（） 在AJAX响应中可以看到方法，但在此过程中却不能看到，您会向我解释为什么会发生这种情况吗？

I am trying to get the PHP threads progress via AJAX, but the strange think I am facing right now is that any code before startPool() method can be seen in the AJAX response but not after it, would you explain to me why this is happening?

重要的Apache Weberver信息

尝试通过命令行运行ajaxthread.php，并查看forkhandler.php）是否与（exit（exit（））一起使用。因为您执行AJAX请求，所以我想您通过Apache Web服务器运行。在这种情况下，exit（）不起作用，您应该使用：

posix_kill(getmypid(), SIGKILL);

Important Apache webserver information

Try to run AjaxThread.php through command line and see if it works with (exit() in ForkHandler.php). Because you do an ajax request I suppose you run this through an apache webserver. In this case the exit() does not work, you should use instead:

posix_kill(getmypid(), SIGKILL);

此行：

for($i = 0; $i < 10; ++$i) {

更改

for($i = 0; $i < 10; $i++) {

Change this line:

for($i = 0; $i < 10; ++$i) {

to

for($i = 0; $i < 10; $i++) {
