安装
此库不需要其他库。

用法
验证器
要创建验证器的实现,您需要实现接口 \District5\Validator\ValidatorInterface
或扩展提供的抽象类 \District5\Validator\AbstractValidator
。
一个StringLength验证器的示例验证器可能如下所示
use \District5\Validator\AbstractValidator; class StringLengthValidator extends AbstractValidator { protected $errorMessages = [ 'notString' => 'Value is not a string', 'tooShort' => 'Value is below the minimum string length', 'tooLong' => 'Value exceeds the maximum string length' ]; private $min; private $max; public function __construct(int $min, int $max) { parent::__construct(); $this->min = $min; $this->max = $max; } public function isValid($value): bool { if (!is_string($value)) { $this->setLastErrorMessage('notString'); return false; } $len = strlen($value); if ($len > $this->max) { $this->setLastErrorMessage('tooLong'); return false; } if ($len < $this->min) { $this->setLastErrorMessage('tooShort'); return false; } return true; } }
