Does PHP keep backward compatibility?

I ever used some open source PHP soft (forums and wikis) several years ago. The development of these soft has been discontinued for a long time now.

Recently, I decided to re-install the php4 age but failed. There are too many APIs and syntax are broken now.

Anyone else have the same experiences?

They try somewhat to warn what will break in future releases. So you get a few releases of warnings and then a release of THIS WILL BREAK NEXT RELEASE and then it breaks. One thing for PHP is a huge 'customer' is the Wordpress universe and they have been good about not breaking Wordpress. But with PHP 8 that will change.

If you are on PHP4 and are moving to the 7.x series plan for some pain.

My problem is I try to find things that will work with flat files. I just spent some time moving from Mediawiki to PMwiki, because of the database nonsense in keeping that in sync with PHP and Mediawiki.

I'd love to find a CRM tool that had the flexibility shown here but would live in flat files that I may have a chance to import into something else.
