Have you ever tried to validate an object in PHP. Maybe you use Models, ViewModels or RequestModels.Maybe you hate writing if-else, loops and swiches to check your values.Maybe you do not like to use different validators for every framework.

At least I do.

So I present you my general solution using the strengths of PHP 8.Clean, concise and easy.

Lots of validations
Supprots also nested object validation
Repeatable validation attributes
Works with private properties and methods
Works with constructor promotion
Memory and time profiling
Custom error messages
Custom property and method names for the exceptions

Example

<?php

use RMValidator\Attributes\PropertyAttributes\Collection\UniqueAttribute;
use RMValidator\Attributes\PropertyAttributes\File\FileExtensionAttribute;
use RMValidator\Attributes\PropertyAttributes\File\FileSizeAttribute;
use RMValidator\Attributes\PropertyAttributes\Numbers\RangeAttribute;
use RMValidator\Attributes\PropertyAttributes\Object\NestedAttribute;
use RMValidator\Attributes\PropertyAttributes\Strings\StringContainsAttribute;
use RMValidator\Enums\ValidationOrderEnum;
use RMValidator\Options\OptionsModel;
use RMValidator\Validators\MasterValidator;

require __DIR__ . '/vendor/autoload.php';


class Test 
{
    public function __construct(
        #[RangeAttribute(from:10, to:50)]
        #[RangeAttribute(from:10, to:30)]
        public int $param)
    {

    }

    #[RangeAttribute(from:10, to:30)]
    const propTest = 40;

    #[UniqueAttribute()]
    public function custom() {
        return ['asd', 'asdk'];
    }

    #[FileSizeAttribute(fileSizeBiggest: 20, fileSizeLowest: 10)]
    #[FileExtensionAttribute(expected:['php'])]
    private function getFile() {
        return __FILE__;
    }

    #[FileSizeAttribute(fileSizeBiggest: 20, fileSizeLowest: 10)]
    #[FileExtensionAttribute(expected:['php'])]
    public string $file = __FILE__;

    #[StringContainsAttribute(needle:"asd")]
    public string $string = "23asd";

    #[RangeAttribute(from:10, to:30)]
    public int $prop = 40;
}

class UpperTest
{
    #[NestedAttribute(excludedProperties:['param'])]
    private Test $test;

    public function __construct(Test $test) {
        $this->test = $test;
    }
}

$test = new Test(40);

try {
    MasterValidator::validate(new UpperTest($test), 
    new OptionsModel(orderOfValidation: [ValidationOrderEnum::PROPERTIES, 
                                         ValidationOrderEnum::METHODS,
                                         ValidationOrderEnum::CONSTANTS], 
                     excludedMethods: ['getFile'], 
                     excludedProperties: ['file']));
} catch(Exception $e) {
    var_dump($e);
}

Enjoy. Any feedback, recommendations and support are welcome :)
