Why is my $_ENV Empty and Populating $_SERVER Twice?

Why is my $_ENV Empty and Populating $_SERVER Twice?

When attempting to access environment variables through the $_ENV variable, users may encounter empty results. This issue arises due to the inability of $_ENV to be populated unless explicitly allowed in the php.ini configuration file, which is typically disabled by default, particularly in the WAMP server. By modifying the variables_order directive to "EGPCS," $_ENV can be enabled, allowing access to environment variables.

Another peculiar behavior observed is the duplication of environment variables in the $_SERVER array when using SetEnv in the .htaccess file. While SetEnv is expected to populate $_ENV, it instead assigns these variables to $_SERVER.

To avoid these complexities, it is recommended to utilize the getenv() function, which remains unaffected by the PHP settings for $_ENV and is case-insensitive, providing an additional level of flexibility.
