Description:
------------
When I try to call apache_getenv(...), PHP claims that 
the function doesn't exist.  The function is present in 
the online PHP manual.

Reproduce code:
---------------
echo apache_getenv('SOME_ENV_VARIABLE');

Expected result:
----------------
VALUE_OF_SOME_ENV_VARIABLE

Actual result:
--------------
Fatal error: Call to undefined function: apache_getenv() 
in /www/php/dryerase/config.php on line 21

Yes, it is available, but only with Apache2.
Documentation should have a note about it.

This requirement has been documented, but some questions: 

1) Assuming putenv() or apache_setenv() aren't used, will apache_getenv(), getenv(), and the Superglobals always have the same value?

2) How do these functions differ? putenv() vs. apache_setenv(), etc.

These functions differ only in availability (both of them may or may not exist) and utilization of safe_mode AFAIK. They are bound in the meaning that apache_setenv("X", "a") affects getenv("X") but putenv("X=a") doesn't affect apache_getenv("X").

This has been documented.
