The biggest problem in the PHP world is there's a wealth of functions and software that people don't use. Sometimes it's for lack of knowledge (PEAR? Composer? What's that?) but all too frequently it's outright hostility to the very idea, like if it isn't PHP core it's not even worth considering. `password_hash` and `password_verify` have been around for ages now and if your PHP is old enough that it doesn't support it, that PHP version is no longer actively supported and is probably riddled with unpatched security holes, so good luck with that!
