Regular expression to validate phone number in PHP?

Question

PHP

Hello,
can you please tell me how to fix this.

if (preg_match('/((8|\+7)-?)?\(?\d{3,5}\)?-?\d{1}-?\d{1}-?\d{1}-?\d{1}-?\d{1}((-?\d{1})?-?\d{1})?/', $login_phone)) {
...
}

so that the phone number is checked strictly according to the format [phone]

Thank you in advance

if (preg_match('/^\+7 \(\d{3}\) \d{3}-\d{2}-\d{2}$/', $login_phone)) {
    echo 'ok';
} else {
  echo 'wrong number';
}

PHP preg_match
