PHP Validator
Validate PHP source against configurable version, typing, naming, structure, and project-style rules. Unlike the quick checker, this tool focuses on rule compliance.

What this developer tool does
It applies a selected validation profile, counts passed and failed rules, and reports required fixes separately from optional improvements.
Structural checks → profile requirements → version compatibility → naming rules → compliance score.
Passing this validator does not guarantee runtime success. Use php -l, static analyzers, tests, and your project coding standard for final verification.
Example
Input: an untyped snake_case class.
Strict output: missing strict_types, namespace, parameter types, return types, and PascalCase naming.
Tips for better output
- Use Modern PHP for new projects.
- Use Custom when migrating legacy code gradually.
- Do not enable rules your runtime version cannot support.
FAQ
How do I validate PHP code against PHP 8.2 rules?
Select a profile, enter 8.2, and run validation to check selected modern syntax and project rules.
How can I check whether PHP code uses strict types?
Enable Require strict_types. The validator checks for declare(strict_types=1).
How do I validate PHP class and method naming conventions?
Enable naming checks to flag class names that are not PascalCase and methods that are not camelCase.
How can I detect PHP version compatibility issues?
Set the target version. The validator compares known feature patterns such as enums and readonly properties with that target.
What is the difference between a PHP checker and a PHP validator?
The checker finds likely mistakes quickly; the validator measures compliance against an explicit ruleset.
