virtualsue I don't use PHP, and I'm probably not the only one. Could you please add a brief description of what 'print_r' does?

It prints out data items and references, it traces complex data structures down to the last item (arrays, hashes), example (PHP, so be warned!):

<?php
$record = array(
            'convict' => array( 'name'  => 'virtualsue',
                                'link'  => 'www.perlmonks.org/?node_id
+=70099'),
            'penalty' => array( 'type'  => '48h TV w/out breaks',
                                'warden'=> 'Mike Judge')
          );
 print_r($record);
?>

The last line produces exactly the following output:

Array
(
    [convict] => Array
        (
            [name] => virtualsue
            [link] => www.perlmonks.org/?node_id=70099
        )

    [penalty] => Array
        (
            [type] => 48h TV w/out breaks
            [warden] => Mike Judge
        )
)
