In this tutorial you will come to know about resource in PHP, it is a new kind of variable introduced in PHP. It is used to make and keep a reference of another file or connection with the database etc.

PHP Resource Type:

In PHP, resource is a special type of variable. Main task of this variable is to hold a reference to an external resource like   connection to database, a file etc.

In PHP 4's Zend Engine a reference counting system is introduced, if no resource is automatically detected then it is freed by garbage collector. That's why we do not need to free the memory manually.

PHP Resource Example:

<?php

$a=mysql_connect("localhost","root","");

echo get_resource_type($a);

?>

Output:

mysql link
