Problem with ‘apache_getenv’ since upgrading to PHP 8

I’m hoping to get some help with an Apache/PHP 8 issue I’m encountering. Since upgrading to PHP 8 on my LAMP server, my logs have been outputting the following error:

PHP Fatal error:  Uncaught Error: Call to undefined function apache_getenv() ...

I’ve done a quick debug with var_dump(is_callable('apache_getenv')) and the value returns as bool(false).

I’ve attempted:

• Disabling PHP 8, restarting Apache, re-enabling PHP 8, and restarting Apache again
• Restarting my whole Linux system, system (for the heck of it)

Nothing seems to work and I’m a bit stumped on how to fix this. My application depends on a few environmental variables set in my site .conf file, so apache_getenv is important.

Is this just the case of a missing module or a bad install? What am I missing?

Any help would be appreciated.

For reference, my system is running Ubuntu 18.04.5

Thanks!

UPDATE: Based on @C. Celora’s recommendation above, getenv() seemed to solve my overarching problem of not being able to get my environmental variables via apache_getenv(). Thank you!

I still haven’t figured out why apache_getenv doesn’t work on my PHP 8 install, but that’s no longer a blocker for me.
