This article mainly introduces how to distinguish between the test environment and the formal environment by setting system environment variables in PHP, which has a certain reference value, and interested friends can refer to it. I hope you will gain a lot after reading this article.

First, introduction

Environment variables can be obtained in 1.PHP through the getenv () function and $_ ENV.

two。 Environment variables are stored in the system and do not change with the submission of the code

3. If the company has two test servers and formal servers, it is a good way to distinguish the test environment from the formal environment by means of environment variables.

4. Safe, don't worry about submission overwrite

Second, setting method

1. Open the etc/profile file: vim ~ / etc/profile

Add an environment variable export PHP_ENV= "test", and set the official server to = "prod"

In this way, you can do some different operations through the system environment variables, or there may be different database account passwords.

Reload after setting: source ~ / etc/profile

two。 Modify the php-fpm.conf file of PHP and set the PHP environment variable

Add at the bottom: Env [PHP _ ENV] = $PHP_ENV

Restart the PHP service, service php-fpm restart

3. What if getenv ('PHP_ENV') can't get the value?

It may be because php.ini does not load the $_ ENV variable definition by default. If you look at phpinfo () at this time, you will find that the environment variable we set is "no value"

Modify vim / etc/php/php.ini

Modified: variables_order:variables_order= "EGPCS"

Restart the PHP service

4. Check phpinfo (), or use the getenv () function to get variables

If it is not available, use $_ ENV; because the getenv function is no longer supported in version 7.
