Given the first example on the print_r() manual page, do you think 
anyone who understands this:

<?php
$a = array ('a' => 'apple', 'b' => 'banana',
             'c' => array ('x', 'y', 'z'));
print_r ($a);
?>

Array
(
     [a] => apple
     [b] => banana
     [c] => Array
         (
             [0] => x
             [1] => y
             [2] => z
         )

)

would have trouble understanding this?

<?php
$a = array ('a' => 'apple', 'b' => 'banana',
             'c' => array ('x', 'y', 'z'));
echo json_encode($a,JSON_PRETTY_PRINT);
?>

{
     "a": "apple",
     "b": "banana",
     "c": [
         "x",
         "y",
         "z"
     ]
}
