php不能始终显示对文件的更改 [英] php not showing changes to files consistently

问题描述

我正在更改php文件，但有时没有显示.有时它们会立即显示.有时我不得不等待几分钟.我已经检查并关闭了所有可以关闭的缓存.问题是不一致的，很难一贯地重复.

I am making changes to php files and they are not showing -- sometimes. Sometimes they will show immediately. Sometimes I have to wait a few minutes. I've gone through and turned off all the cache that I could think to turn off. The problem is inconsistent and tough to duplicate consistently.

推荐答案

回答我自己的问题...

Answering my own question...

我花了很长时间进行试验以一致地重现该行为.我不得不让服务器坐了几分钟，而没有刷新任何页面.然后，如果在刷新页面之前更改文件，则更改将立即显示，而所有后续更改将立即显示.如果我先刷新页面，然后对文件进行更改，则直到我刷新10到20次左右，才显示后续更改.

I spent quite awhile doing trials to consistently reproduce the behavior. I had to let the server sit without refresh any page for a few minutes. Then if I change the file before I refresh the page, the change show immediately and all subsequent changes show immediately. If I refresh the page first, then make a change to the file, then no subsequent changes show until I refresh 10-20 times, or so.

顺便说一句，html文件显示所有更新，无论如何，因此这是一个php问题.

BTW, html files show all updates regardless, so it was a php issue.

在找到答案之前，我尝试过...

Before finding the answer, I tried...

• 关闭nginx缓存
• 将nginx conf设置为sendfile off;
• 将nginx conf设置为expires off;

• turning off nginx cache
• setting nginx conf to sendfile off;
• setting nginx conf to expires off;

...这些都不起作用.然后，我发现它实际上是OPcache.我通过将php.ini文件更改为此(并重新启动所有服务)来解决了该问题

... none of these work. I then found that it was in fact OPcache. I fixed the issue by changing the php.ini file to this (and restarting all services)

opcache.enable=0
