Argus is a PHP package designed to simplify and streamline data validation tasks in your applications. It offers a comprehensive set of validation rules to ensure the integrity and accuracy of your data.

Features

• Common Validations: Perform checks for required fields, email format, string values, numeric values, and length restrictions.
• Range Validation: Ensure numeric data falls within a specific range.
• Customization: Easily define custom validation rules to meet your specific needs.
• Error Reporting: Get clear and informative error messages to identify invalid data points.

Installation

You can install the package using Composer:

composer require yiiy/argus

Usage

The package provides a simple and intuitive API for data validation. Here's a basic example:

<?php

require 'vendor/autoload.php';

use Yi\Argus\Validator;

$data = [
    'name'  => 'John Doe',
    'email' => 'invalid_email',
    'age'   => 30,
];

$rules = [
    'name'  => ['required', 'string', 'length:2:255'],
    'email' => ['required', 'email'],
    'age'   => ['required', 'numeric', 'between:18:120'],
];

$validator = new Validator();
$errors = $validator->validate($data, $rules);

if (empty($errors)) {
    echo 'Data is valid!';
} else {
    echo 'Validation errors:' . PHP_EOL;
    foreach ($errors as $field => $errorMessages) {
        echo "  * $field: " . implode(', ', $errorMessages) . PHP_EOL;
    }
}
