Usage

Basic Phone Number Processing

use carono\yii2\helpers\PhoneHelper;

// Clear phone number from non-digit characters
$cleanNumber = PhoneHelper::clear('+7 (123) 456-78-90'); // returns '71234567890'

// Normalize phone number (returns null if number doesn't match any known country code)
$normalized = PhoneHelper::normalNumber('+7 (123) 456-78-90'); // returns '71234567890'

// Format phone number according to its country code mask
$formatted = PhoneHelper::asString('71234567890'); // returns '+7 (123) 456-78-90' for Russian numbers

Using in Yii2 Models

use carono\yii2\helpers\PhoneFilter;

public function rules()
{
    return [
        [['phone'], PhoneFilter::class],
        // or with custom validation
        [['phone'], 'filter', 'filter' => [PhoneHelper::class, 'normalNumber']],
    ];
}
