Displaying 5 rows of data from query - php

Question

I have a simple table (mgap_orders) with customer orders in it. Multiple have the the same id (mgap_ska_id) and I simply want to pull 5 records from the table and display all five.
I can easily get one record with the following query and PDO, but how can I display 5 rows instead of only one row?
$result_cat_item = "SELECT * FROM mgap_orders WHERE mgap_ska_id = '$id' GROUP BY mgap_ska_id";
while($row_cat_sub = $stmt_cat_item->fetch(PDO::FETCH_ASSOC))
{
$item=$row_cat_sub['mgap_item_description'];
$item_num=$row_cat_sub['mgap_item_number'];
$item_type=$row_cat_sub['mgap_item_type'];
$item_cat=$row_cat_sub['mgap_item_catalog_number'];
$item_ven=$row_cat_sub['mgap_item_vendor'];
$item_pur=$row_cat_sub['mgap_item_percent_purchased'];
$item_sales=$row_cat_sub['mgap_item_sales'];
}

Answer 1

Use limit 5 then put the results in an array, like this:
$result_cat_item = "SELECT * FROM mgap_orders WHERE mgap_ska_id = '$id' GROUP BY mgap_ska_id LIMIT 5";
$items = array();
while($row_cat_sub = $stmt_cat_item->fetch(PDO::FETCH_ASSOC))
{
$items['item'] = $row_cat_sub['mgap_item_description'];
$items['item_num'] = $row_cat_sub['mgap_item_number'];
$items['item_type'] = $row_cat_sub['mgap_item_type'];
$items['item_cat'] = $row_cat_sub['mgap_item_catalog_number'];
$items['item_ven'] = $row_cat_sub['mgap_item_vendor'];
$items['item_pur'] = $row_cat_sub['mgap_item_percent_purchased'];
$items['item_sales'] = $row_cat_sub['mgap_item_sales'];
}
Then you can do:
foreach($items as $item) {
// echo $item['item'] or whatever
}
EDIT: Or you can skip putting them in the array and just use the while() to do what you need to do with the data.
