Automatic PHP 7 Compatibility Checking Using php7cc
summary
Two static checkers run and disagree: php7cc and PHPCompatibility (PHP_CodeSniffer) run via composer against real repos, show different unique errors and warnings, and do not auto-fix. On a 2,364‑file codebase php7cc takes ~276s and PHPCompatibility ~271s; Zend Framework snapshot reports ~330 compatibility items while Slim shows zero and Symfony only a few. The tools point to concrete failures (reserved class names, PHP4 constructors, removed extensions, bitwise shifts) with filenames and line numbers so fixes are actionable.
