Need assistance for php loanpplication logic

1

Hi im fairly new in php, i have this code working well but i have been given further instructions and im struggling with logic. This is one of the files in my app. It is a loan application developed in php. When a client borrows less than $5500,the amount should be paid in 5 months at 15%, else any amount greater than $5500 should be paid in 12 months at 22%. When i enter an amount i expect the program to calculate this. check the code below

<?php extract($_POST); if(isset($save)) { if($source=="" || $amount=="" || $group=="" || $payment=="" || $due=="") { $err="fill all the fileds first"; } else { $sql=mysqli_query($conn,"select * from loan where group_id='$group'"); $r=mysqli_num_rows($sql); if($r!=true) { mysqli_query($conn,"insert into loan values('','$group','$source','$amount','$intereset','$payment_term','$total_paid','$emi_per_month','$payment','$due')"); $err="Congractulations Rising Star Member grants Loan to this Member"; } else { $err="Loan already allotted to this Member"; } } } ?>
