Mysql data will show "Array" in table column - php

Question

I want to ask about my php coding..
I'am doing some array coding but when I submit my data, in my database is will display an array at the 'description' and 'qty' column..
I use mysql..
Below is my array coding..
$item = array(
'item_description' => '',
'price' => '',
'qty' => '',
'amount' => '',
);
foreach ($item as $key => $value){
$item_description = $_POST['item_description'][$key];
$price = $_POST['price'][$key];
$qty = $_POST['qty'][$key];
$amount = $_POST['amount'][$key];}
}
This is my insert query.
$sql1="INSERT INTO payment_item (payment_id, payment_item_id, item_description, price, qty, amount)
VALUES
('$last_insert_payment_id','NULL','$_POST[item_description]','$_POST[price]','$_POST[qty]','$_POST[amount]')";
This is my form:
<form>
<h1>Payment Item</h1>
Payment ID :<input id="payment_id" name="payment_id" type="text"><br>
<input type="button" value="Add Row" onClick="addRow('tableID')"/>
<input type="button" value="Delete Row" onClick="deleteRow('tableID')"/>
<table class="table" bgcolor="#CCCCCC">
<thead>
<tr>
<td></td>
<td><center>Item Description</center></td>
<td><center>Price (RM)</center></td>
<td><center>Month</center></td>
<td><center>Amount (RM)</center></td>
</tr>
</thead>
<tbody id="tableID">
<tr>
<td><input type="checkbox" name="chk"></td>
<td>
<select name="item_description">
<option value="deposit">Deposit</option>
<option value="rental">Rental</option>
<option value="stamp">Stamp Duty</option>
<option value="process">Process Fee</option>
<option value="ap">AP</option>
</select>
</td>
<td><input id="price" name="price" type="text"></td>
<td><input id="month" name="qty" type="text"></td>
<td><input id="amount" name="amount" type="text"></td>
</tr>
</tbody>
</table>
<input name="submit" type="submit" value="Submit">
<input name="reset" type="reset" value="Reset">
</form>
I'am sorry for my poor english language..
But I really need any help from someone for this..
Thank you..

Answer 1

A word 'Array' appears when PHP is trying to cast an array as a string.
So for the field appeared as Array you have to process it somehow, depends on your application logic, converting whatever array you have to a proper string.
The question has nothing to do with mysql though.
Also remember that you have to format your SQL strings. At the very least do
$var = mysql_real_escape_string($var);
for the every variable you're putting into query, and wrap it single quotes in the query.

Answer 2

I don't know what your $_POST contains. But i assume you need this
<?php
$item = array(
'item_description' => '',
'price' => '',
'qty' => '',
'amount' => '',
);
foreach ($item as $key => &$value)
{
$value = $_POST[$key];
}
?>
EDIT:
You have to specify a form method
<form method="post">
and finally the INSERT query as
$sql1="INSERT INTO payment_item (payment_id, payment_item_id, item_description, price,qty, amount) VALUES ('$last_insert_payment_id','NULL','$item[item_description]','$item[price]','$item[qty]','$item[amount]')";
