Consider the following code:
<?php
$conn = mysql_connect('localhost', 'username', 'password');
mysql_select_db('database', $conn);
?>
This works as expected, but how does PHP know what database connection to use when calling mysql_select_db() in the following example?
<?php
mysql_connect('localhost', 'username', 'password');
mysql_select_db('database');
?>
