Examining an Array with print_r()

   <source lang="html4strict">

<html> <head> <title>Testing the print_r() Function</title> </head> <body>

<?php $characters = array ( 

     array (
       "name"=> "bob",
       "occupation" => "A",
     ),
     array (
       "name" => "sally",
       "occupation" => "B",
     )
  );

print_r( $characters); ?>

</body> </html> 

 </source>


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

   <source lang="html4strict">

<? 

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

?> 

 </source>
