phpstan-rules
=============

[](#phpstan-rules)

Opinionated rules for [PHPStan](https://github.com/phpstan/phpstan).

Installation
------------

[](#installation)

Run:

```
composer require --dev pereorga/phpstan-rules
```

Usage
-----

[](#usage)

To enable all [rules](https://github.com/pereorga/phpstan-rules#rules), reference [`rules.neon`](rules.neon) in your `phpstan.neon` file:

```
includes:
    - vendor/pereorga/phpstan-rules/rules.neon
```

To enable only specific rules, include their individual configuration files from the [`rules/`](rules/) directory:

```
includes:
    - vendor/pereorga/phpstan-rules/rules/no-redundant-boolean-comparison.neon
    - vendor/pereorga/phpstan-rules/rules/snake-case-variable.neon
```

Rules
-----

[](#rules)

### `NoRedundantBooleanComparisonRule`

[](#noredundantbooleancomparisonrule)

[`rules/no-redundant-boolean-comparison.neon`](rules/no-redundant-boolean-comparison.neon)

Disallows comparing boolean expressions with `=== true`, `=== false`, `!== true`, or `!== false`. Use the boolean value directly instead.

### `NoNonReferenceParameterAssignmentRule`

[](#nononreferenceparameterassignmentrule)

[`rules/no-non-reference-parameter-assignment.neon`](rules/no-non-reference-parameter-assignment.neon)

Disallows assigning values to parameters that are not passed by reference. Encourages the use of separate working variables.

### `NoSuperfluousPhpDocTypesRule`

[](#nosuperfluousphpdoctypesrule)

[`rules/no-superfluous-phpdoc-types.neon`](rules/no-superfluous-phpdoc-types.neon)

Detects `@param` and `@return` tags that redundantly duplicate type information already present in native type declarations. Encourages using prose descriptions (e.g., "The name parameter specifies...") for simple types, and `@param`/`@return` tags only for complex types (array shapes, generics).

### `SnakeCaseFunctionRule`

[](#snakecasefunctionrule)

[`rules/snake-case-function.neon`](rules/snake-case-function.neon)

Requires all function names to be written in `snake_case`.

### `SnakeCaseParameterRule`

[](#snakecaseparameterrule)

[`rules/snake-case-parameter.neon`](rules/snake-case-parameter.neon)

Requires all parameter names to be written in `snake_case`.

### `SnakeCaseVariableRule`

[](#snakecasevariablerule)

[`rules/snake-case-variable.neon`](rules/snake-case-variable.neon)

Requires all variable names to be written in `snake_case`.

### `PDOFetchModeRule`

[](#pdofetchmoderule)

[`rules/pdo-fetch-mode.neon`](rules/pdo-fetch-mode.neon)

Ensures that `PDOStatement::fetch()` and `PDOStatement::fetchAll()` are always called with an explicit fetch mode.
