The why and the how of moving to 7.x
summary
Argument: upgrade because PHP 7 delivers dramatic wins — 200–300% speed and up to 50% memory reduction — while adoption sits low (only 12% on PHP 7 vs 87% still on PHP 5, with large slices on 5.3/5.4). Practical migration uses static tools (PHPCompatibility as a PHP_CodeSniffer standard, php7cc, Phan, Docker images) inside CI to catch deprecated constructors, removed extensions (mysql, mcrypt), changed error handling and type/nullable differences; PHPCompatibility runs and flags real errors and warnings.
