question about PHP ordering latest products

I don't understand how concatenating $list_view_html at the end instead of before get_list_view_html($product_id, $product) reverses the order of the products? Can you help me understand why this works?

If i understand correctly, you can change the order of the results by doing for example "ORDER BY date DESC"

Hi Eric,

I believe it works like this. First, to simplify things we are going to call $list_view_html $lvh and get_list_view_html($product_id,$product) glvh(). If I'm wrong I hope someone corrects me.

Jeff

<?php

$lvh = "";

$lvh = $lvh . glvh(101);
// $lvh now eguals 101

$lvh = $lvh . glvh(102);
// $lvh now equals 101, 102

$lvh = $lvh . glvh(103);
// $lvh now equals 101, 102, 103

$lvh = $lvh . glvh(104);
// $lvh now equals 101, 102, 103, 104

// Now let's switch things around

$lvh = glvh(101) . $lvh;
// $lvh now eguals 101

$lvh = glvh(102) . $lvh;
// $lvh now eguals 102, 101

$lvh = glvh(103) . $lvh;
// $lvh now eguals 103, 102, 101

$lvh = glvh(104) . $lvh;
// $lvh now eguals 104, 103, 102, 101
