At times, applications may require the creation of an internal server environment variable, such as you might set up with the SetEnv directive in Apache. You can set up server environment variables in OpenLiteSpeed, too.

Server Side Setup

In the Environment field, add the variables TEST_VALUE and TEST_VALUE2, like so:

TEST_VALUE=Hello
TEST_VALUE2=World

Save and restart OpenLiteSpeed.

$test2 = getenv('TEST_VALUE2');

echo $test1.' '.$test2;

Access test.php from the browser, and you should see the values that were set at the server level, like so:
