Saving multiple entries in mysql on pressing save, confusing me

Unity Engine
1

// I am using this to save 1 entry in 1 row of the table ie company name, company address

public void button1_Click(iGUIButton caller){
               
                string output = "'" + textfield2.value + "','" + textarea2.value + "'";
                StartCoroutine(PutData("parsecustomerstext.php", output));
       
        }
       
               
       
        IEnumerator PutData(string phpDoc, string data){
                var form = new WWWForm();
                form.AddField( "direction", "put" );
                form.AddField("data", data);
                WWW www = new WWW("http://funiks.com/invoice/" + phpDoc, form);
                yield return www;
                Debug.Log(www.text);
        }

my php code for this-

if($_POST["direction"] == "put"){
	// make sql here
	$data = $_POST["data"];
	print($data);
	$sql = "insert into customers (name,billingaddress1) values ($data)";
	print GetData($sql);
}

// Now i want to save multiple entries like

//company name company address
//company name company address
//company name company address
//company name company address
//company name company address

for this i need to do 2 things

  1. scrollview which creates input fields on pressing a “add” button, i fill company name, address,and again press the add button if required and so on.

  2. save all on pressing the “save” button

Please help me on how to do it for n rows, i am too new to php, please try to keep it simple

i dont know if i got this but, one thing is for sure.
in mysql if you want to insert multiple lines at the same time, you cant pass at the same values position, the correct way is this:

INSERT INTO customers (name,billingaddress1)

VALUES (‘costumer_string’, ‘addresss_string’),
(‘costumer_string2’, ‘addresss_string2’),
(‘costumer_string3’, ‘addresss_string3’)

there you go. (btw i work with php and mysql for more than 10 years if you have more questions just ask.)
