Inserting array into table - php

Question

I am trying to insert data from array to mysql table. If I have for example in array three items, the result of echo is Item1Item2Item3 but in the mysql table is inserted only Item3. Why it dont repeat inserting into table?
<?php
session_start();
foreach($_SESSION['cart'] as $item){
$sql="INSERT INTO eshopadmin (Item)
VALUES
('$item[item]')";
echo $item[item];
}
?>

Answer 1

Try something like this:
<?php
session_start();
$data; //array that will store all the data
foreach($_SESSION['cart'] as $item){
// push data to the array
array_push($data,$item[item]);
$data= implode(",", $data);
}
$sql="INSERT INTO eshopadmin (Item)
VALUES
('$data')";
?>

Answer 2

Very common practise to use implode and explode for retrieving arrays to and from a database table field.
$array = array('a','b','c');
$sql = 'INSERT INTO eshopadmin (Item) VALUES ("'.implode(',', $array).'")';
the array is stored as a,b,c
and when retrieving it :
$row = mysql_fetch_assoc($result);
$array = explode(',', $row['Item']);

You could use prepared statements as well. I'm used to MySQLi.
<?php
// loop only if cart is array and has items
if( is_array( $_SESSION['cart'] ) && count( $_SESSION['cart'] ) ){
// autocommit off
$mysqli_instance->autocommit( false );
// prepare insert sql
$insert_statement = $mysqli_instance->prepare( '
INSERT INTO eshopadmin
( Item )
VALUES
( ? )
' );
// bind variables to the statement
$insert_statement->bind_param( 'i', $item_array_item_value );
// loop throught array
foreach( $_SESSION['cart'] as $item ){
$item_array_item_value = $item['item'];
$insert_statement->execute();
}
// manually commit
$mysqli_instance->commit();
// restore autocommit
$mysqli_instance->autocommit( true );
}
