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";
$id1 = new MongoId();
echo "$id2\n";
?>`

El resultado del ejemplo seria algo similar a:

    49a7011a05c677b9a916612a
    49a702d5450046d3d515d10d

Note that the second hexidecimal number is greater than the first.

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);
?>`

El resultado del ejemplo seria algo similar a:

    bool(true)
