Printing Arrays

Problem
You want to print the contents of an array.
Solution
Use PHP’s print_r() or var_dump() functions: 
<?php
// define array
$data = array(
"UK" =>array(
"longname" => "United Kingdom", "currency" => "GBP"),
"US" =>array(
"longname" => "United States of America", "currency" =>↵
"USD"), "IN" =>array(
"longname" => "India", "currency" => "INR"));
// print array contents
print_r($data);
var_dump($data);
?>

demonstrates them both in action. Note that var_dump() produces more verbose output (including information on data types and lengths) than print_r()
