Sample PHP+Mongo app on Heroku

1. Install any of the Mongo add-ons available at http://addons.heroku.com

2. Vendor the Mongo driver with your application. You can download it here:

   https://github.com/wuputah/heroku-libraries/raw/master/php/mongo/mongo.so
   

   Add it to a folder like "ext".

3. Add a php.ini file to the root of your application:

   extension_dir = "/app/www/ext/"
   extension=mongo.so
   

4. Use it! Parse the db name out of the env var (keep in mind different Mongo providers will give you different urls, like MONGOHQ_URL or MONGOLAB_URL).

   Here's a sample index.php:

   <?php
     # get the mongo db name out of the env
     $mongo_url = parse_url(getenv("MONGO_URL"));
     $dbname = str_replace("/", "", $mongo_url["path"]);
   
     # connect
     $m   = new Mongo(getenv("MONGO_URL"));
     $db  = $m->$dbname;
     $col = $db->access;
   
     # insert a document
     $visit = array( "ip" => $_SERVER["HTTP_X_FORWARDED_FOR"] );
     $col->insert($visit);
   
     # print all existing documents
     $data = $col->find();
     foreach($data as $visit) {
       echo "<li>" . $visit["ip"] . "</li>";
     }
   
     # disconnect
     $m->close();
   ?>
   

--Issue resolved by adding compose.json in root directory with following code

   {
     "require": {
         "ext-mongo": "*"
      }
   }
