Lots of warning due to PHP7.3 PCRE2

[shahariaazam]

The original DOM parser library used https://github.com/sunra/php-simple-html-dom-parser. It seems that sunra/php-simple-html-dom-parser library has been abandoned.

Due the recent changes in PHP7.3 (PCRE engine). It's showing lots of warnings. That repo already has a PR sunra/php-simple-html-dom-parser#63 . But kept un-marged. So planning to change this library in future.

PHP Warning:  preg_match(): Compilation failed: invalid range in character class at offset 4 in /var/www/DSE-Share-Market-Update/vendor/sunra/php-simple-html-dom-parser/Src/Sunra/PhpSimple/simplehtmldom_1_5/simple_html_dom.php on line 1378
