How Can I Convert a PHP Array to a JavaScript Array Using JSON?

Convert PHP Array to Javascript

Problem:

How can PHP arrays be converted into Javascript arrays that follow a specific format, such as the one provided for city names?

Solution:

While the provided PHP and Javascript arrays are not directly related, PHP offers the json_encode() function to convert arrays into Javascript code in JSON (JavaScript Object Notation) format.

<?php
$php_array = array('001-1234567', '1234567', '12345678', '12345678', '12345678', 'AP1W3242', 'AP7X1234', 'AS1234', 'MH9Z2324', 'MX1234', 'TN1A3242', 'ZZ1234');
$js_array = json_encode($php_array);
echo "var javascript_array = " . $js_array . ";\n";
?>

The output will be the following Javascript code:

var javascript_array = ["001-1234567","1234567","12345678","12345678","12345678","AP1W3242","AP7X1234","AS1234","MH9Z2324","MX1234","TN1A3242","ZZ1234"];

Note that json_encode() is available in PHP versions 5.2 and later. For older PHP versions, alternative functions may be available in the PHP manual.
