summary
Graphs show PHP and JavaScript trends mirroring each other while PHP powers 82% of the web. Composer ecosystem counts over 100,000 packages and almost 7 million installs per month, signaling stability. PHP 7 delivers major speedups — PHP 7 is 2.4x faster and uses much less memory — and PHP 7.1 adds concrete features: missing-argument exceptions (ArgumentCountError), negative string offsets, Closure::fromCallable, class constant visibility, multi-catch, improved list/iterable support, void and nullable types, and ongoing RFCs toward PHP 7.2 and beyond.
