Helper class to launch Sublime

Sublime.php

<?php

class Sublime
{

    /**
     * Sublime shell command
     */
    const COMMAND = 'subl';

    /**
     * Launch sublime and open file
     *
     * @param  string $file
     * @return void
     */
    public static function openFile($file)
    {
        exec(self::COMMAND .' '. $file);
    }

    /**
     * Get Sublime file url (clickable URL from the browser)
     *
     * @param  string $file
     * @return string
     */
    public static function fileUrl($file)
    {
        return self::COMMAND . '://open?url=file://' . $file;
    }

}

Just make sure subl is in your $PATH. Although if you follow this tutorial, the command sould be sublime
