NGINX（ubuntu）非常好的PHP网址

I am having a lot of difficulty configuring nginx pretty urls with php. I am trying to rewrite /verify/codehere (code example: dsifoj24234j) to verify.php?key=codehere

Here is my current config:

 location ^/verify/(.*)$ {
      /verify.php?key=$1 last;
 }

 location / {
      try_files $uri $uri/ /index.php;
 }

.. Its not working which brings me here, please help me :<

location ^/verify/(.*)$ {
    try_files /verify.php?key=$1 =404;
}

# or

rewrite ^/verify/(.*)$ /verify.php?key=$1 last;
