Validators

Regex Validator

This validator allows you to validate if a given string conforms a defined regular expression.

It will not automatically cast integers or floats to string prior to evaluation - when provided a non string value, validation will fail.

Supported Options

The following options are supported for Laminas\Validator\Regex:

  • pattern: Sets the regular expression pattern for this validator.

Basic Usage

Validation with regular expressions allows complex validations without writing a custom validator.

$validator = new Laminas\Validator\Regex(['pattern' => '/^Test/']);

$validator->isValid("Test"); // returns true
$validator->isValid("Testing"); // returns true
$validator->isValid("Pest"); // returns false

The pattern uses the same syntax as preg_match(). For details about regular expressions take a look into PHP's manual about PCRE pattern syntax.
