是什么限制了我的PHP资源? [英] What's limiting my PHP resources?

问题描述

我在从PHP获取更多内存方面遇到问题.

I'm having a problem getting more memory out of PHP.

这是错误消息:

Fatal error: Allowed memory size of 20971520 bytes exhausted (tried to allocate 82 bytes) in ...

但是:

我已将php.ini文件中的memory_limit设置为32M:

I've set memory_limit in the php.ini file to 32M:

memory_limit = 32M;

我还尝试在实际脚本中手动覆盖它:

I've also tried to override it manually in the actual script:

ini_set('memory_limit', '32M');

而且-这是我迷路的地方-我已通过phpinfo()确认此php.ini文件是所使用的实际ini文件，并且memory_limit似乎设置正确. memory_limit上的这一行给出了这一点:

And -- here's where I'm lost -- I've confirmed via phpinfo() that this php.ini file is the actual ini file used, and the memory_limit seems to be set correctly. The line on memory_limit gives this:

memory_limit    32M 32M

因此，似乎所有配置都正确，但是我只能得到20971520字节(〜20M).

So it would seem that everything is configured properly, but I'm only getting 20971520 bytes (~20M).

我还应该在哪里寻找施加此限制的地方?

Where else should I be looking to figure out where this limitation is being imposed?

编辑:我正在VPS上的Ubuntu 9.04上的nginx/fastcgi下运行php. php-cgi进程似乎确实有点资源紧张(RES = 25m，VIRT = 187m)，但是我有10m的物理内存可用空间和500m的交换空间可用.

I'm running php under nginx/fastcgi, on Ubuntu 9.04 in a VPS. The php-cgi processes do seem to be a bit resource-hungry (RES=25m, VIRT=187m), but I have 10m of physical memory free and 500m of swap space free.

推荐答案

我只是仔细研究了正在运行的代码，并且有人将其硬编码为配置文件:

I just pored over the code I was running, and someone had hard-coded this into a config file:

ini_set('memory_limit', '20M');

那是我正在做的所有事情的重中之重.哇.

Which was overriding everything else I was doing. Whew.
