print_r() not printing array

for some reason when i use print_r() on this array it only prints array().
can someone explain to me why?

here is the code

PHP Code:


		
			
if($_REQUEST['do']=="index")

{

    $vbjclass= new vbjournal();

    

    $cache= $vbjclass->cache_journals();

    print_r ($cache);

    $journals= $vbjclass->grabjournals($cache);

}

}

It'd only print array() if the array is empty.

Just as an FYI, heres the function I always use when I mack for dumping vars. pretty handy if you ask me :)

PHP Code:


		
			
function debug_array($array,$echo_on_empty=1;$title='Values'){
    if (is_array($array)){
     echo("<br /> Array: $title<hr><pre>");
     print_r(array_values($array));
     echo("</pre><br />End Array $title<hr>");
    }elseif($echo_on_empty){
echo("<br />Array $title is empty!<br />");
 
}
}
