The security support for all PHP versions below 7.3 has been officially over for quite some time, we believe the risk of using them is growing higher for your web site security. Also the performance of websites using old PHP versions is considerably lower.
We are discontinuation of PHP 7.2, 7.1, 7.0, 5.6 and all clients need to update their web site to latest PHP version for better web site security. Please contact your web designer / web developer if your web site using php scripts.
Your php files will not work properly if not update with correct php version.
