Alternative for too many switch case for cyclomatic complexity reduction?

Question

I have a function for checking the type of a $value is valid or not. My current code is a simple switch case with too many cases exceeding the cyclomatic complexity to 17. I need to add more cases as well as reduce the complexity.

 /**
 * Check type of attribute value
 * @param $type
 * @param $value
 * @return bool
 */
public function typeCheck($type, $value)
{
    $this->value = $value;
    switch ($type) {
        case 'string':
            return is_string($value) || is_integer($value) || is_bool($value);
        case 'StringNotNull':
            return is_string($value);
        case 'LongStringNotNull':
            return is_string($value);
        case 'SuperLongStringNotNull':
            return is_string($value);
        case 'FortyStringNotNull':
            return is_string($value) && (strlen($value) < 41);
        case 'integer':
            return is_numeric($value);
        case 'positiveInteger':
            return is_numeric($value) && ($value > 0);
        case 'boolean':
            return is_bool($value) || ($value == 'true' || $value = 'false');
        case 'float':
            return is_numeric($value);
        case 'decimal':
            return is_numeric($value);
        case 'PositiveDimension':
            return is_numeric($value) && ($value > 0);
        case 'Dimension':
            return is_numeric($value) && (strlen($value) < 13);
        case 'Barcode':
            $validator = $this->getBarcodeValidator();
            $validator->setBarcode($value);
            return is_string($value) && (strlen($value) < 17 && $validator->isValid());
        case 'dateTime':
            return true;
        case 'normalizedString':
            $this->value = strip_tags($value);
            return is_string($value);
        default:
            return is_string($value);
    }
}

Any better way around?

You could replace the switch with a data structure:

public function typeCheck($type, $value) {

    $typeTestMap = [
        'string' => function($value) { return is_string($value) || is_integer($value) || is_bool($value); },
        'FortyStringNotNull' => function($value) { return is_string($value) && (strlen($value) < 41); },
        ...
    ];

    if (isset($typeTestMap[$type])) {
        return $typeTestMap[$type]($value);
    } else {
        return is_string($value);
    }
}
