PHP Command to Check the Syntax of a Chess PGN File

#### Repository
https://github.com/programarivm/pgn-chess

![white-chess-pieces.jpg](https://cdn.steemitimages.com/DQmTM9BF4xn2N3LQRPbH7941eTiA6fUHiJtRsiEEP3x66GV/white-chess-pieces.jpg)

PGN Chess for PHP is a simple, friendly, and powerful PGN (Portable Game Notation) library for running chess games from within PHP applications. It is a chess board representation that can be used in chess engines, chess applications and chess algorithms.

### New Features
[Feature/pgnsyntax](https://github.com/programarivm/pgn-chess/pull/3) is a new command to check the syntax of a PGN file:

- `pgnsyntax.php`

The PR is the continuation of [PHP Command That Converts a PGN File into a MySQL Script](https://steemit.com/utopian-io/@programarivm/php-command-that-converts-a-pgn-file-into-a-mysql-script). It is also an improvement of `pgntomysql.php` -- now PGN files are converted to MySQL `INSERT` statements as long as they are syntactically correct.

Example: 

    php pgnsyntax.php games.pgn
    Whoops! Sorry but this is not a valid PGN file.

Hi @codingdefined, thanks for the review. 

Yep, it is better to divide the work across multiple commits. Let me just note that I am squash merging my new features as it is shown in this example: [Feature/pgnsyntax (#3)](https://github.com/programarivm/pgn-chess/commit/3e2390e1f315918f915d5b674f7606cb6aa3feae)

Is that okay? :) I'd like to squash merge the branches to keep the history of the project a bit more concise. 

On the other hand, here is the reason behind so many additions. I just added  a few sample PGN files for testing purposes, and those ones contain thousands of lines -- [games-02.pgn](https://github.com/programarivm/pgn-chess/blob/3e2390e1f315918f915d5b674f7606cb6aa3feae/tests/unit/PGN/File/data/games-02.pgn) is an example having 10004 lines.

Minor Correction

You have a minor misspelling in the following sentence: <blockquote>At this moment the project is in a position to start loading thousands and thousands of chess games into a database for futher processing.</blockquote> It should be <i>further</i> instead of <i>futher</i>.
