问题
I want to set an env variable that has the DOC_ROOT info but nothing
SetEnv PROJECT_BASE %{ENV:DOC_ROOT}
SetEnv LAYOUT_HOME %{ENV:PROJECT_BASE}"/html/app/wordpress/"
and then be able to access LAYOUT_HOME in php
How can I do this?
回答1:
Variables are accesible via :
$_SERVER["LAYOUT_HOME"] and $_SERVER["PROJECT_BASE"] global variable.
A simple test if to execute the next command in php
<?php phpinfo(); ?>
and check if the variable is present and is defined.
If not, then may be exist some restricting in the php installation ( for example in a share ambiance - sharedhosting)

So far it's not possible. All you can do is to set request headers with RequestHeader. So you'll have you variable in environ but with "HTTP_" prefix.
