Domain-Specific Language Class for PHP

Hi guys, I am coding a cool project so, I developed my own class in PHP to manage my DSL for the project. I want to share a short version of the class I coded and, I hope you will find it useful.

<?php

include("PHPDSL.php");

# My own code
$input  = 'search port:80 protocols:HTTP';

# Start the analyzer
$result = PHPDSL::analyze($input);

# Print results. Pss: use firefox to view results.
header("Content-type:application/json");
echo json_encode($result);

1. Imagine your own syntax: <command> <option>:<parameter>
2. Write your regex code for each element: <command> => /^(\w+)/. Tip: this website can be helpful Regex101
3. Always remember to use ^ at start and, always to include the match between ()
4. Add/substitute the regex code into the PHPDSL.php file

protected static $syntax = 
 [
    "/^(\w+)/" => "COMMAND", 
    "/(\s+)/" =>   "WHITESPACES" 
 ];

5. Be careful when you order the regex codes!!!
6. Good WorK!
