 New Comment:

I find it highly unlikely that PHP itself is randomly deciding to set auto_prepend_file to
php://input.
Compare the phpinfo outputs from the two different pages - are they perhaps using different php-fpm
pools or configurations?

I thought perhaps this was caused by a misconfiguration but I found that even if I explicitly set
auto_prepend_file = none, the problem persists.

I have tested by creating a php script <?php phpinfo(); ?> and when I refresh the page over
and over I see the auto_prepend_file setting keeps changing back and forth from none to php://input

Here is a screen cap demonstrating the problem: https://www.dropbox.com/s/2kofxya97gmydpi/Nov-22-2020%2014-17-58.mp4?dl=0

I can confirm the same issue is happening with my PHP-FPM instance. I have tested all the way up to
7.4 and the problem persists.

Steps to reproduce.
1. Create script called /test.php with code <?php echo "foo"; ?>
2. Make a POST request with post params bar=1 via x-www-form-urlencoded or raw to a PHP endpoint
over http.

Expected Result:
Response body should be "foo"

Actual Result:
Response body includes post params prepended to the HTTP response.
i.e. "bar=1test"

When this happens, rockmongo installed on the same machine has the same problem. After restarting
PHP FPM, the response is correct. I met some people in a discussion group. Have you ever recorded
such a bug.

Description:
------------
PHP-fpm runs stably, but after a period of time, the post data is automatically added to the
response data. After restarting PHP-fpm, the response is correct. After a period of time, this
problem occurs again


Expected result:
----------------
request data：page=1&rows=20
response data：
{response data}

Actual result:
--------------
page=1&rows=20{response data}
