HELP WITH PRODUCTS OF PAGES, PRODUCTS PER PAGE ETC

[Orionsbelter]

Hi there, i am currently wanting to make a shop for myself and need to know how i can make the code, so that my page shows 20 products per page, or a choosen amount such as 20, 40, 60 etc, then have pages 1,2,3 etc depending on the amount of products.

 

so for example i am viewing 20 products, so the page shows the first 20 products i click page 2 i shows the next 20, how can i do this

 

thank you

$numofproductsperpage = 20;

$i = 1;
while ( $i < $numproductsperpage)
{

show product

$i++;
}

$numofproductsperpage = 20;

$i = 1;
while ( $i < $numproductsperpage)
{

show product

$i++;
}

 

Just out of curiousity is there any reason why you use a while loop instead of a for loop?

As far as I know there is no real difference between for or while except for claims of speed
