从表中只列出品牌一次

Question

I have a table of products. Each product has a field for 'brand'

I need to list all the brands on my page, but more than 1 product can have the same brand. How do i list the brand only once? Soi say that 5 products have the same brand name im not getting that brand name 5 times.

$data=mysqli_query($link, "Select brand FROM products");
while($info=mysqli_fetch_array($data)){
$output .= '<div class="brands">';
$output .=$info["brand"];
$output.='</div>';

This outputs every instance of brand

Thanks

SELECT DISTINCT brand FROM products

这应该工作。
