A PHP library providing efficient assertions for validating method input and output, throwing InvalidArgumentException with clear, consistently formatted error messages on failure. It is a popular Composer package inspired by beberlei/assert with improved error message usability.

Use cases

  • validate method arguments in php
  • assert value is a string or integer
  • throw exceptions with nice error messages
  • defensive programming input checks
  • validate constructor parameters
  • replace manual type checks with assertions

When to choose

  • you need lightweight input validation in PHP with readable error messages
  • you want consistent sprintf placeholder ordering in assertion messages
  • you prefer a small dependency over a full validation framework

When to avoid

  • you need complex rule-based or schema validation
  • you want assertions that fail softly instead of throwing exceptions
  • you are not working in PHP
