NoVerify

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 sub optimally, please report issue.
• This tool is written in Go and uses fork of z7zmey/php-parser.

Features

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. Auto fixes for some warnings;
4. PHP 7 and PHP 8 support;
5. Diff and baseline modes support.

Default lints

NoVerify by default has the following checks:

• Unreachable code
• 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

• Incorrect access to private/protected elements
