Problem with get_resource_type()

[pablogosse]

Hi all. I've got the following small snippet of code:

<?php
$fp = fopen("phone_list.inc.php","r");
echo get_resource_type($fp)."\n";
?>

which should theoretically print "file" to the screen.

However, all it gives me is:

Fatal error: Call to undefined function: get_resource_type() in /home/gossep/public_html/unbcvirtroot/csam/test.php on line 3

Anyone know why this is happening?

Thanks in advance,
Pablo

It was added in version 4.02. You must be using an older version.
