1、关于Illuminate/Validation验证器

composer require illuminate/validation

2、composer.json 文件

{
  "name": "song/test",
  "description": "validator.",
  "keywords": ["validator"],
  "license": "MIT",
  "type": "project",
  "autoload": {
    "psr-4": {
      "App\\": "app/"
    }
  },
  "require": {
    "php": "^7.2",
    "illuminate/validation": "^7.16"
  },
  "minimum-stability": "dev",
  "prefer-stable": true
}

3、项目中使用，源码如下

require_once './vendor/autoload.php';

class Validator extends \Illuminate\Validation\Factory
{
    /***
     * 创建实例
     *
     * @return \Illuminate\Validation\Factory
     */

    public static function getInstance()
    {
        static $validator = null;
        if ($validator === null) {
            $test_translation_path = __DIR__ . '/lang';
            $test_translation_locale = 'zh_cn';
            $translation_file_loader = new \Illuminate\Translation\FileLoader(new \Illuminate\Filesystem\Filesystem,
                $test_translation_path);
            $translator = new \Illuminate\Translation\Translator($translation_file_loader, $test_translation_locale);
            $validator = new \Illuminate\Validation\Factory($translator);
        }
        return $validator;
    }

}


//验证数据

$data = [
    'title' => '123457',
    'status' => 1
];
//验证规则
$rules = [
    'title' => 'required|string|min:2|max:5',
    'status' => 'required|integer'
];

//错误消息
$messages = [
    'title.max' => '标题不能大于5位'
];

//属性名称
$attributes = [
    'title' => '名称',
    'status' => '状态',
];

$validator = Validator::getInstance()->make($data, $rules, $messages, $attributes);
if ($validator->fails()) {
    echo 'fail';
}else{
    echo 'ok';
}
echo "\n";
//输出错误消息

print_r($validator->errors()->first());
