About

With Tokenizer you can easily convert a string to a stream or array of tokens. You can use it for syntax highlighting or a syntax parser. If you wish more features feel free to contribute.

Installation

If Composer is installed globally, run

composer require robinthehood/tokenizer

How to use

Code

require 'vendor/autoload.php'; // if you are using Composer

$tokenizer = new RobinTheHood\Tokenizer\Tokenizer(__FILE__, 'token_php.php');
$tokens = $tokenizer->getAllTokens();
print_r($tokens);

Result

You get an array of token objects:

Array
(
    [0] => Tokenizer\Token Object
        (
            [type] => T_UNKNOWN
            [value] => <?
            [position] => 2
        )

    [1] => Tokenizer\Token Object
        (
            [type] => T_IDENT
            [value] => php
            [position] => 5
        )

    [2] => Tokenizer\Token Object
        (
            [type] => T_UNKNOWN
            [value] =>

            [position] => 6
        )

    [3] => Tokenizer\Token Object
        (
            [type] => T_COMMENT
            [value] => /*
            [position] => 8
        )

    [...]

Parameters

new Tokenizer(FILE_PATH, DESCRIPTION_FILE_PATH)

FILE_PATH:
Is the File you want to spilt into tokens

DESCRIPTION_FILE_PATH:
