compwright/philter
==================

[](#compwrightphilter)

[![PHP Composer](https://github.com/compwright/philter/actions/workflows/php.yml/badge.svg)](https://github.com/compwright/philter/actions/workflows/php.yml)

A user-friendly interface for the PHP filter module

- Easy to use type-hinted API with IDE support
- Sticks to a reasonable subset of functionality (FILTER\_VALIDATOR\_\*) and eschews deprecated and removed `filter` features
- Values fall back to null by default
- Supports named parameters
- All objects are readonly, inspectable, and idempotent
- High code quality that passes PHPStan level 9 and a full suite of unit tests

Supported Validators:

- Boolean
- Integer
- Float
- Regexp
- Email
- Url
- Domain
- Ip
- Mac
- Callback

Each one utilizes the corresponding `FILTER_VALIDATE_*` constant, with its supported options and flags.

Prerequisites
-------------

[](#prerequisites)

- PHP 8.5+
- PHP ext-filter module

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

[](#installation)

```
composer require --save compwright/philter

```

Example Usage
-------------

[](#example-usage)

```
use Compwright\Philter\Input;
use Compwright\Philter\Phactory;

// Args shown with defaults for demo purposes; omit if defaults are desired.
$ph = new Phactory(throwOnFailure: false, default: 'foo');

// Factory settings can be changed idempotently later
$ph2 = $ph->throwOnFailure(false)->setDefault(null);
assert($ph2 !== $ph1);

// Validators can be executed directly or on standard inputs
$boolean = $ph->boolean();
$featureFlag = $boolean('true');
$featureFlag = Input::get('feature-flag', $boolean);
$featureFlag = Input::post('feature-flag', $boolean);
$featureFlag = Input::cookie('feature-flag', $boolean);
$featureFlag = Input::server('feature-flag', $boolean);
$featureFlag = Input::env('feature-flag', $boolean);

// Validator-specific configuration
$integer = $ph->integer(min: -100, max: 100, allowOctal: true, allowHex: true);
assert($integer('42') === 42);
assert($integer('-27') === -27);
assert($integer('0b1') === 1); // binary
assert($integer('0o1') === 1); // octal
assert($integer('0x1') === 1); // hexadecimal
assert($integer(27.5) === null); // wrong type
assert($integer('142') === null); // out of range
```
