Answer 1

foreach ($arrayName as $key) {
    $user_status = explode(",", $key);
    //print_r($user_status);
}
$i = 1;
$total_phone_num = count($user_status);
$before_last = $total_phone_num - 1;

$valid_phone_num = "'";

foreach ( $user_status as $valid_phone){
 
if ($i <= $before_last){
$valid_phone_num = $valid_phone_num."+234".$valid_phone.",";
}else{

$valid_phone_num = $valid_phone_num."+234".$valid_phone."'";
}
$i = $i + 1;
}

echo $valid_phone_num;
