Examining an Array with print_r()

<div>
<?php
$characters = array (
      array (
        "name"=> "bob",
        "occupation" => "A",
      ),
      array (
        "name" => "sally",
        "occupation" => "B",
      )
   );
print_r( $characters);
?>
</div>
</body>
</html>



print_r(,true ) passes its output back as its return value, and not print anything out.

 
<?
    $myarray = array("Apples", "Oranges", "Pears");
    $size = count($myarray);
    $output = print_r($myarray, true);
    print $output;
?>
