PHP breaks things all the time (just check the migration guides for any release), but the difference is that they break only what they must, and deprecate things in a timely way so you can evolve your codebase instead of having to rewrite it. Other platforms tend to see a broken piece that needs replacement as a good opportunity to redesign everything else as well, even the stuff that worked fine, and don&#x27;t put as high a value on easy migration paths.<p>Ofcourse, that&#x27;s also one of the reasons PHP has so much ugliness still.
