问题
For an application based on Zend Framework I use apaches SetEnv in .htaccess. I use this on test, staging and production servers like so:
SetEnv APPLICATION_ENVIRONMENT production
On the staging server I couldn't read this env var in PHP. However when I did a var_dump( $_ENV ) in php I got the value but the key was prepended with REDIRECT_ becoming
REDIRECT_APPLICATION_ENVIRONMENT
Can anybody explain why this is happening, and how I can prevent this?
回答1:
I'm guessing you have mod_rewrite rules in your .htaccess as well for Zend? I believe it may be mod_rewrite prepending that when it does a redirect so that the value won't be overridden by any new settings with the new URL.
回答2:
I had the same issue and it was because of was running PHP as cgi in my Apache.
After enabling mod_php, I could access to my variable without that prefix.
