Is this correct and what would the recommended procedure then be since I do need 5.6 for this. Use Remi's collection or something else?

Everyone using PHP is happy to get a current release. If your application insists on using 5.6 then move on and look for a different application. >> >> Alexander >> > > That was not helpful.

Just in case anybody comes across this thread, please read what is written on the page referred to by Alexander Dalloz: >> PHP 5.6 is EOL. https://www.php.net/supported-versions.php This in plain English language says that php 5 is not supported by vendor since Jan 1 2019, i.e. almost a year a a half now. This means that PHP development team does not release security patches, and even though RedHat "backports" patches to older versions, difference in internals between PHP version 5 and version 7 is quite significant, so you should not assume that even if RedHat team still backports security patches for issues discovered in version 7, you are safe: there may be still be issues in version 5 which by no means are discovered by anyone. This boils down to one thing. If you still have anything using PHP version 5.[any] you should migrate this to PHP version at least 7.2. You ideally should have done that before Jan. 1, 2019. I hope, this helps somebody. By no means I meant to question the brilliant job RedHat does backporting (taking my hat off and bowing to RedHat here). However, as I said, there may be bugs in PHP 5 that will not be relevant to PHP 7, hence there is nothing to backport to fix them.
