Detect screen size in php

Detecting the screen size in php, is not something that can be done with php alone but the following is what I use to kind of get around it.

Get next AUTO INCREMENT value from a mysql table

SELECT AUTO_INCREMENT as 'next_id' FROM information_schema.TABLES
WHERE TABLE_SCHEMA = 'db_name' AND TABLE_NAME = 'table_name';

 Restoring a fsarchiver file to a temporary block device.
