Setting Environment Variables in MAMP Pro (Nginx)

Question

How does one set Environment Variables in MAMP Pro when using Nginx?

Existing questions on Stack Overflow focus on an Apache implementation: Setting Environment Variables in MAMP?

These variables need to be retrievable from PHP using \getenv()

My attempted solution is the following:

//Edit Jan 4: I later realized the path to include for fastcgi_params was incorrect, it has since been fixed to: include /Applications/MAMP/conf/nginx/fastcgi_params; however, the environment variables are still not functioning

PHP:

<?php

\var_dump( \getenv('DB_DSN') ); 
//outputs 'bool(false)'

Here is another attempt trying to set the Environment Variable TEST:

PHP:

<?php

\var_dump( \getenv('TEST') ); 
//outputs 'bool(false)'

The PHP server variables, for example: `["SERVER_SOFTWARE"]=> string(12) "nginx/1.13.2"` `["GATEWAY_INTERFACE"]=> string(7) "CGI/1.1"` — JimmyBanks, Jan 05 '20 at 00:28
You sure the workers running your code are going through that location block? Try removing that block and/or adding env variables to other location blocks. — bishop, Jan 05 '20 at 00:35
I've included the `fastcgi_param` lines in the `@php` block which is functioning (it directs to the correct PHP file names), but still no environment variables being set — JimmyBanks, Jan 05 '20 at 00:50
The mamp config defines a `TEST` variable, but the code looks for a `DB_DSN` variable. Typo, or source of current problem? — bishop, Jan 05 '20 at 22:15
Sorry above the image I explained it, the 2nd image attempts to set the variable `TEST`, the php code has been updated appropriately for that variable, I'll update the content to reflect that more clearly — JimmyBanks, Jan 05 '20 at 22:25

I had the same problem and could not set environmental variables in nginx as easily as apache.

Actually your first solution does not work because the content "Additional Parameters for directive" is placed after this directive generated by MAMP.

location ~ \.php$ {
            try_files        $uri =404;
            fastcgi_pass     unix:/Applications/MAMP/Library/logs/fastcgi/nginxFastCGI_php7.2.1.sock;
            fastcgi_param    SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include          /Applications/MAMP/conf/nginx/fastcgi_params;
        }

Your location directive is then ignored by nginx since it comes after the one generated by MAMP on the same location (.php$).

This is the workaround. MAMP recreates at every server startup the nginx.conf file. This is created using a template. You can actually modify the templates to generate a conf file the suits your needs.

This is the link to the MAMP documentation. https://documentation.mamp.info/en/MAMP-PRO-Mac/Menu/File/

I edited the nginx.cenf template to add the content of the "Additional Parameters for directive" box right before the creation of the location done by MAMP.

Edit the nginx.conf in MAMP. File > Edit Template > nginx
Locate the keyword MAMP_VirtualHost_AdditionalCustom_MAMP and remove it

Place the same directive just in front of this block

    MAMP_VirtualHost_AdditionalCustom_MAMP

    MAMP_Nginx_ReverseProxy_IF_MAMP
    # proxy the PHP scripts to Apache
    location ~ \.php$ {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_pass http://MAMP_Apache_IP_MAMP:MAMP_Apache_Port_MAMP;
    }
    MAMP_Nginx_ReverseProxy_ELSE_MAMP
    location ~ \.php$ {
        try_files        $uri =404;
        fastcgi_pass     unix:/Applications/MAMP/Library/logs/fastcgi/nginxFastCGI_phpMAMP_PhpHost_MAMP.sock;
        fastcgi_param    SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include          /Applications/MAMP/conf/nginx/fastcgi_params;
    }
    MAMP_Nginx_ReverseProxy_END_MAMP

After restart for me it worked. You can fiddle around with a more sophisticated solution.
