If I make a HTTP request to the server I am able to access the environment variable using getenv()['FOO'] but I am not able to access the environment variable using getenv('FOO'). The same issue occurs with the Caddy server. If I set the environment variable in the fpm configuration using env[FOO]=bar the issue does not occur. If I run the script from the CLI or the built in web server it works as expected. Test script: --------------- <?php $env = getenv(); var_dump(array_key_exists('FOO', $env)); var_dump($env['FOO']); var_dump(getenv('FOO')); Expected result: ---------------- I expect to see the output: bool(true) string(3) "bar" string(3) "bar" Actual result: -------------- I see the output: bool(true) string(3) "bar" bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77782&edit=1
