PHP paging code

Let me give you a class. it's very simple,
// Paging function
Class pg {
Function genpage (& $ SQL, $ page_size = 2)
{
Global $ prepage, $ nextpage, $ pages, $ sums; // out param
$ Page = $ _ GET ["page"];
$ Eachpage = $ page_size;
$ Pagesql = strstr ($ SQL, "from ");
$ Pagesql = "select count (*) as ids". $ pagesql;
$ Result = mysql_query ($ pagesql) or die (mysql_error ());
If ($ rs = mysql_fetch_array ($ result) $ sums = $ rs [0];
$ Pages = ceil ($ sums-0.5)/$ eachpage)-1;
$ Pages = $ pages> = 0? $ Pages: 0;
$ Prepage = ($ page> 0 )? $ Page-1: 0;
$ Nextpage = ($ page <$ pages )? $ Page + 1: $ pages;
$ Startpos = $ page * $ eachpage;
$ SQL. = "limit $ startpos, $ eachpage ";
}
Function showpage ()
{
Global $ page, $ pages, $ prepage, $ nextpage, $ queryString;
$ QueryString = $ _ SERVER ['query _ string'];
If (preg_match ("/page/", $ queryString )){
$ QueryString = strstr ($ queryString ,"&");
} Else {
$ QueryString = "&". $ queryString;
}

$ Shownum = 10/2;
$ Startpage = ($ page >=$ shownum )? $ Page-$ shownum: 0;
$ Endpage = ($ page + $ shownum <= $ pages )? $ Page + $ shownum: $ pages;
$ Xs = "";
$ Xs. = "total". ($ pages + 1). "page :";
If ($ page> 0) $ xs. = "homepage </a> ";
If ($ startpage> 0)
$ Xs. = "...? </A>... the remaining full text>

PHP paging code

Include ("connection. php ");
$ PerNumber = 10; // number of records displayed on each page
$ Page = $ _ GET ['Page']; // Obtain the current page value.
$ Count = mysql_query ("select count (*) from user"); // obtain the total number of records
$ Rs = mysql_fetch_array ($ count );
$ TotalNumber = $ rs [0];
$ TotalPage = ceil ($ totalNumber/$ perNumber); // calculate the total number of pages
If (! Isset ($ page )){
$ Page = 1;
} // If no value exists, 1 is assigned.
$ StartCount = ($ page-1) * $ perNumber; // start by page. calculate the start record based on this method.
$ Result = mysql_query ("select * from user limit $ startCount, $ perNumber"); // calculate the start record and number of records based on the previous calculation.
While ($ row = mysql_fetch_array ($ result )){
Echo "user_id:". $ row [0]."
";
Echo "username:". $ row [1]."
"; // Display the database content
}
If ($ page! = 1) {// The page number is not equal to 1
?>
"> Previous Page </a>
}
For ($ I = 1; $ I <= $ totalPage; $ I ++) {// The page is displayed cyclically.
?>
"> </A>
}
If ($ page <$ totalPage) {// if the page is smaller than the total number of pages, the next page link is displayed.
?>
"> Next page </a>
}
?>
