+
+Example
+-------
+
+The following example changes the expiration time of a TTL collection in the
+``test`` database:
+
+.. code-block:: php
+
+   <?php
+
+   $db = (new MongoDB\Client)->test;
+
+   $result = $db->modifyCollection('users', [
+       'keyPattern' => ['lastAccess' => 1],
+       'expireAfterSeconds' => 1000
+   ]);
+
+   var_dump($result);
+
+The output would then resemble::
+
+   object(stdClass)#2779 {
+     ["expireAfterSeconds_old"]=>
+     int(3)
+     ["expireAfterSeconds_new"]=>
+     int(1000)
+     ["ok"]=>
+     float(1)
+   }
