My (crazy) attempt to create an installer for CodeIgniter - andersonsalas - 06-04-2015

Hi  Big Grin

I made a kind of installer to the framework. Basically it is a .zip file that downloads the latest version of CodeIgniter and makes a few adjustments automatically. The process takes 1 to 2 minutes.

(Yes, laziness taken to another level)


PS: A quick script and I have not verified that works on all OS / platforms Honestly, it's just for fun.


The code:

Code:
<?php

set_time_limit(0);

$file_target = 'ci_dist.zip';
$ci_dist_folder_name = 'CodeIgniter-3.0.0';


function post_install(){
   /*

   echo '<script>window.location = "index.php"</script>';

}
