当用户登陆页面时如何设置URL变量？

Question

On my home site it has pagination but this pagination only works when there is a page variable set in the URL, e.g. http://www.example.com/index?page=1

However if the user just lands on my index page it won't have the page variable set and the results on my page wont display as no page number has been set, so I wanted to know if there is a way of setting the URL variable when the user just lands on the page and the variable isn't set?

Answer 1

define a variable for

$page for default value and use isset

that u may use for getting $_GET[] values if exist or not

if(isset($_GET['page'])){
   $page = $_GET['page']
}
else{
   $_GET['page'] = //set default value for page..
}
