Example 1: print array php

<?php
$a = array ('a' => 'apple', 'b' => 'banana', 'c' => array ('x', 'y', 'z'));
echo "<pre>";
print_r ($a);
echo "</pre>";
?>
  
Output:

Array
(
    [a] => apple
    [b] => banana
    [c] => Array
        (
            [0] => x

// raw array output
print_r($arr);

// the above well-formatted
echo '<pre>'; print_r($array); echo '</pre>';

// more details like datatype and length
var_dump($arr);

// output that PHP understands
var_export($arr);

// by foreach loop
foreach($arr as $key=>$value)
  echo $key, '=>', $value;	// $value must be convertible to string
