What is Pagination - PHP

Pagination :

If Database Tables contains more rows like hundreds

Than your output of that table would be heavy in webpages,

Than pagination works : Pagination gives you a power to breakup the database tables to php pages break into parts with limit query.

And You would divide that hundreds of table into like limit of 10 or 20 per page.

Than Limit works like 0 to 9, 10 to 19, etc...

and your pagination works like

<<prev 1 2 3 4 5 .... 1001 1002 next>>
