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)
}
