My code:
const T = 'test';
const B = 'boat';
$const_var = getenv('FOO');
In my VirtualHost section, I have:
SetEnv FOO T
Obviously $const_var evaluates to the character T
.
What I want to do is to be able to use the value of local const T, by using the value of the environment variable as a reference. Is there a way to do that?
You can use the constant()
function to resolve the value indirectly.
print constant($_ENV["FOO"]);
Or in your case $const_var
as parameter.
