启动一个可以稍后通过PHP访问的变量的Apache服务？

Question

I have a need to start the Apache service with a parameter so that I can later access that parameter via PHP. Is this possible?

Answer 1

pass the parameter to httpd with the -C or -c ( process the configuration directive before/after reading config files ) command line option and the SetEnv directive:

httpd -C "SetEnv FOO bar"

FOO can now be accessed from PHP like so:

<?php
print getenv('FOO');

prints

bar

Answer 2

You can set an environment variable. See also: getenv

Answer 3

Based on the comments on your question, I'd say that using shared memory is an acceptable alternative. Take a look at shmop_open() et alia.

Answer 4

使用-c启动httpd程序时，它会采用“指令”，因此请尝试使用该指令和SetEnv。
