Hi i need stepwise explanation of following code used here

 

<?php
require_once "../database/dbConnect.php";
$search = $_GET['search_keyword'];
$return_arr = array();
        $query = "SELECT * FROM electronics_1 where (id like '%$search%') OR (Product_name like '%$search%') OR ( price like '%$search%')";
        $result = mysqli_query($conn, $query);
        while ($row = mysqli_fetch_array($result)) {
            $id = $row['id'];
            $Product_name = $row['Product_name'];
            $Price = $row['Price'];
            $Wireless_carrier = $row['Wireless_carrier'];
            $Brand = $row['Brand'];
            $Colour = $row['Colour'];
            $Memory_storage_capacity = $row['Memory_storage_capacity'];
            $Screen_size = $row['Screen_size'];
            $return_arr[] = array(
                "id" => $id,
                "Product_name" => $Product_name,
