ผลลัพธ์
พอใส่ข้อมูลทั้งหมดแร้ว ตรง "วงเงินกู้" มันจะคำนวณดอกเบี้ยและจำนวนเงินคืนอัตโนมัติและมาแสดงข้อมูล ตรงคอลัมน์ข้างล่างอะค่ะ

เอาตัวแปรที่เกี่ยวข้อง ที่ต้องการมาลิสต์เป็นรายการ เขียนใส่ กระดาษ
ต้วอย่าง
เงินต้น =$_POST['cost']
เงินต่องวด = $_POST['permonth'];
แล้วใส่สูตรเข้าไป เขียนใน กระดาษ
แล้วค่อยมาแปลงเขียนในโปรแกรม
flowchart flowcontrol เล็กๆ จะทำให้เขียนโปรแกรมง่ายขึ้น
