sanitize_phone_number_malaysia.php

<?php 
$prepare_phone_num = $phone_num;

$phone = $prepare_phone_num;
$phone = str_replace(["-", "–", " ", "+"], '', $phone);

if ("0" == substr($phone, 0, 1))
{
    $phone = "6" . $phone;
}
if ("60" != substr($phone, 0, 2))
{
    $phone = "60" . $phone;
}

return $phone;

kalau macam ini ?

function phone_number_formatter($phone) {

    $phone = str_replace(["-", "–", " ", "+"], '', $phone);
    if(substr($phone,0,1) == '0') {

        return "6".$phone;
    }

    return "60".$phone;
}


echo phone_number_formatter('+143334567');

function phone_number_formatter($phone) {

    $phone = str_replace(["-", "–", " ", "+"], '', $phone);
    return substr($phone,0,1) == '0' ?  "6".$phone : "60".$phone;
}


echo phone_number_formatter('+143334567');
