Examples
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:
49a7011a05c677b9a916612a 49a702d5450046d3d515d10d
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)
