Sure you can't just pick any random framework and assume that it will fit all of your needs, but as a team (assuming you are talking about more general software development practices, and not just solo "I'm Winner" type crap), you should be finding a framework that fits your common use requirements as much as possible so that you have to do much less work building things from the ground up, and "many eyes" will be on the project for defects and security issues, instead of just yours which most likely are not on it much at all. See Andrei Alexandrescu's post on optimization [] where he mentions: On x86 pointers can access byte-aligned data whereas other platforms pointers MUST be 4-byte, etc., aligned else you get a hardware trap. There's a caveat though: before PHP 8 the signature of these method implementations weren't validated. With non-capturing catches, you can omit the variable, so instead of this: Note that it's required to always specify the type, you're not allowed to have an empty catch.
