PHPCompatibility is a set of rules for PHP_CodeSniffer that checks for PHP version compatibility in codebases. It helps developers identify features or syntax not supported in specific versions of PHP, which is critical for maintaining backward compatibility or upgrading PHP versions safely. It supports a wide range of PHP versions and is often used in CI workflows to ensure version compliance.

Features

  • Detects deprecated or removed functions and syntax
  • Supports compatibility checks for PHP 5.3 through 8.x
  • Integrates with PHP_CodeSniffer for automated analysis
  • Configurable to target specific PHP version ranges
  • Identifies changes in function signatures and constants
  • Useful in CI pipelines for validating cross-version support
