    @rapzo - may 18th - 2016 language features from php

    5.3 onwards… the others are rubbish anyways... 5.3 the biggest leap 5.4 array shorthands, traits and a webserver! 5.5 generators (i yield!) and expressions in primitives 5.6 constant expressions, …$params notation 5.7 when everybody went bananas! long wait.... 7.0 major shift
  8. 13.

    @rapzo - may 18th - 2016 php 5.3 namespaces for

    logically code separation late static binding for static inheritance closures don’t we just love to provide functions as arguments! nowdoc & heredoc output buffered content constants immutable data FTW! shorthand ternary ?: ‘hello’; dynamic access to static $a::$b \m/
