I've been reading up on the new features in PHP 7. Being a PHP developer, it's important to keep up on stuff like this.
Reading through the list of changes to PHP, I've become aware of some features that I don't normally use in the course of web development. PHP has so many features that it's possible to write applications in a wide variety of styles with this language.
Namespaces come to mind, for example. Using my own code libraries, I typically don't need to use namespaces but it's certainly a nice feature to have. A lot of how it works reminds me of Flash Actionscript 3.0 (which is a flavor of ECMAscript if I recall correctly). Also, it's derived from Hypercard - which is a VERY old school system that I learned all the way back in High School! We actually had a Hypercard class; it was fun. Of course, that was less programming and more multimedia... kind of a precursor to web development, in a way.
Hmm. That was quite a tangent. Anyway, PHP7 has a lot of changes in regard to objects. I'm not sure it's as much of a leap as PHP4 was to PHP5 in that department but it's still significant.
