$sqlArray = array();
$nameArray = array();
$valueArray = array();

  $nameArray[] = $name;
  $valueArray[] = $value;
 }

$names = implode(', ', $nameArray);
$values = implode(', ', ':'.$nameArray);
$sql = "INSERT INTO customers ( ".$names." ) VALUES ( ".$values." )";

print_r($sql);
$addRandom = $pdo->prepare( $sql );

 foreach($_POST as $name => $value) {
  $addRandom->bindValue($name, $value);

$fields = array_keys($_POST);
if (!empty($fields)) {
    $names = implode('`, `', $fields);
    $values = implode(', :', $fields);

    $sql = "INSERT INTO customers ( `".$names."` ) VALUES ( :".$values." )";
    print_r($sql);

    $addRandom = $pdo->prepare($sql);
    foreach ($fields as $field) {
        $addRandom->bindValue(":{$field}", $_POST[$field]);
    }

    $boolean = $addRandom->execute();
    if ($boolean){
        echo 'INSERTED';
    } else {
        echo 'FAILED';
    }   
}
