get an specific values for a specific key in custom fields WordPress

• SOLVED

I have some custom fields on my wp.

If I use this function:


<?php

$custom_field_keys = get_post_custom_keys();
foreach ( $custom_field_keys as $key => $value ) {
$valuet = trim($value);
if ( '_' == $valuet{0} )
continue;
echo $key . " => " . $value . "<br />";
}
?>


I get this results:

2 => podcast_content
3 => seo_settings


And if I use this function:


<?php $item = get_post_meta($post->ID, 'podcast_content', $single = true) ?><br />
<?php echo print_r( $item ); ?>


I get this result:

Array ( [file] => Dave_McQueen_Mexico_Manufacturing_ Consultant.mp3 [length] => ) 1

So... I think I have two arrays ( file and length) inside the custom field podcast_content.

My question is... how can I get to display only one of the arrays... so it only display the file:

Dave_McQueen_Mexico_Manufacturing_ Consultant.mp3

in place of

<?php $item = get_post_meta($post->ID, 'podcast_content', $single = true) ?><br />
<?php echo print_r( $item ); ?>

use this

<?php $item = get_post_meta($post->ID, 'podcast_content', $single = true) ?><br />
<?php echo $item ; ?>
