Example #1 MongoId::__construct() example
This example shows how to create a new id. This is seldom necessary, as the driver adds an id to arrays automatically before storing them in the database.
<?php
$id1 = new MongoId();
echo "$id1\n";
$id2 = new MongoId();
echo "$id2\n";
?>
The above example will output something similar to:

Example #2 Parameter example
This example shows how to use a string parameter to initialize a MongoId with a given value.
<?php
$id1 = new MongoId();
// create a new id from $id1
$id2 = new MongoId("$id1");
// show that $id1 and $id2 have the same hexidecimal value
var_dump($id1 == $id2);
?>
The above example will output something similar to:
bool(true)
