NoVerify is a PHP linter: it finds possible bugs and style violations in your code.

  • NoVerify has no config: any reported issue in your PHPDoc or PHP code must be fixed.
  • NoVerify aims to understand PHP code at least as well as PHPStorm does. If it behaves incorrectly or suboptimally, please report issue.
  • This tool is written in Go and uses z7zmey/php-parser.


  1. Fast: analyze ~100k LOC/s (lines of code per second) on Core i7.
  2. Incremental: can analyze changes in git and show only new reports. Indexing speed is ~1M LOC/s.
  3. Experimental language server for VS Code and other editors that support language server protocol (version 0.3.0
    and below).
  4. Auto fixes for some warnings (when -fix flag is provided).

Default lints

NoVerify by default has the following checks:

  • Unreachable code
  • Array access to non-array type
  • Too few arguments when calling a function/method
  • Call to undefined function/method
  • Fetching of undefined constant/class property
  • Class not found
  • PHPDoc is incorrect
  • Undefined variable
  • Variable not always defined
  • Case without "break;"
  • Syntax error
  • Unused variable
  • Incorrect access to private/protected elements
  • Incorrect implementation of IteratorAggregate interface
  • Incorrect array definition, e.g. duplicate keys
