PHP Variables to JavaScript Variables in CodeIgniter

Often, you’ll find yourself in situations, where you want to pass some server-side string/array/whatever to your JavaScript. Traditionally, this can be a bit of a pain – especially as your app grows.

“Transform PHP Vars to JavaScript” is a codeIgniter library and it simplifies the process drastically. And it is developed based on “PHP-Vars-To-Js-Transformer” it is developed by JeffreyWay.

How to install

Download the files add put PHPtoJS.php class in your library folder application\libraries\PHPtoJs.php.Now load the library locally or globally.

Locally

1	$this->load->library('PHPtoJS');

Globally
Open you autoload.php file which located at application\config\autoload.php

1	$autoload['libraries'] = array('PHPtoJS');

After loading library, you may use in your controllers as shown below.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

<?php defined('BASEPATH') OR exit('No direct script access allowed'); class Welcome extends CI_Controller {     public function index()     {             $this->load->library('PHPtoJS',['namespace' => 'arjun']);             $this->phptojs->put([                 'foo' => 'bar',                 'age' => 29             ]);         $this->load->view('welcome_message');     } }

Final step – in your layout page or view page add this line, which will print the JavaScript variables.

1	echo $this->phptojs->getJsVars();

That is it.
