Is there a way to limit items on a page using PHP, based on the page resolution?

[helloworld001]

i am creating a responsive website. 

 

I'll give you an example.

 

I am retriving 100 items from mysql database using php.  I am only showing 20 items per page using simple pagination with arrows.  I keep this format on desktop and tablets.  However, I would like to show less items when I am viewing the page on a smartphone.  So instead of 20 items per page, it'll show 5 items per page along with the pagination arrows. 

 

I was wondering if this is possible with PHP or would I have to use javascript?

the number of items per page in your pagination code needs to be a php variable, that gets set to the appropriate value based on detecting the type of client that made the request to your page.

I would start looking in $_SERVER to see if there is anything which indicates the browser so that you could determine the appopriate number or rows to display.

 

If not, then use JavaScript to send a request to provide this information, store it in a session, and use this value to determine the course of action.
