PHP a complete paging class (attached source) _php Tutorial

In PHP to achieve paging is much simpler than ASP, our core is to directly get the current page and then determine how much per page to use limit in the database to achieve paged query, the following I would like to detail the implementation of paging class.

If it is an Ajax call:

$total, Total (int), $size, number of displays per page (int), $page, current page (int), $url, Link (string), Ajax,js function name;

$page = new page (' total ' = $total, ' perpage ' + $size, ' nowindex ' = = $page, ' url ' + = $url, ' ajax ' = ' Videogotopage '));

The variable $page_html is paged html, parameter 4 is the pagination display style is the fourth type
$page _html = $page->show (4);
Then add the jquery package and JS code to the page:

function Videogotopage (U)
{
if (!u)
{
return false;
}
$.ajax ({
Type: "POST",
URL: "" + U,
Data: "",
Success:function (msg) {
Alert ("Data Saved:" + msg);
$ ("#tonglei"). HTML (msg);
}
});
}

If it is not an Ajax call:

Just get rid of the ' Ajax ' in the array.

$page = new page (' total ' = $total, ' perpage ' + $size, ' nowindex ' = = $page, ' url ' = + $url));

$page _html = $page->show (4);

Description: For the URL, because I use pseudo-static, such as my page link is search-1.html represents the first page, search-2.html for the second page, then my

should be written as $url = ' search-';

The paging class automatically complements the following "page. html", where you can modify the paging class to suit your needs.

Let's share the page.class.php with you.

The code is as follows
