It is not the hosting providers that does not support PHP 5.2 it is the PHP community... http://php.net/eol.php
DW server behaviors have been producing old code for the past 10 years, and people started to understand this just now, when finally even their hosting providers dropped support for it... you people as web developers must always be up to date if you wanna stay in the business. The statement that PHP 8 will go out next week and you will have to redo your sites again is just a really really not proper example and next major PHP version is most probably going to be released in like 10 years.
I will once again recommend staying up to date and use the free dmxzone app connect and their commercial db connection extension. My life is so much easier now after purchasing their suite, which is PHP 7 compatible.
