This article describes the php simple paging class implementation method. Share it with you for your reference. The details are as follows:

The Code is as follows:

Class PageModel {
/**
* Retrieve the paging Array
* @ Param unknown $ current page count
* @ Param unknown $ goodsCount Total number of items
* @ Param unknown $ pageLength: Number of displayed pages per page
*/
Public static function getPageArr ($ page, $ goodsCount, $ pageCountLength, $ pageLength ){
// Total number of pages
$ AllPageCount = ceil ($ goodsCount/$ pageLength );
// If the page is always shorter than the length, set the page length to the total number of pages
If ($ allPageCount <= $ pageCountLength ){
$ AllPageCount = ceil ($ goodsCount/$ pageLength );
}
// The total number of pages displayed on one page
If ($ allPageCount <= $ pageCountLength ){
For ($ I = 0; $ I <$ allPageCount; $ I ++ ){
$ Arr [] = array ('page' => $ I + 1 );
}
Return $ arr;
}
// Length before and after
$ HalfLength = floor ($ pageCountLength/2 );
// Because it is too small, put it in the original position, left
If ($ page <= $ halfLength ){
$ Arr = array ();
For ($ I = 0; $ I <$ pageCountLength; $ I ++ ){
$ Arr [] = array ('page' => $ I + 1 );
}
Return $ arr;
}
// It is too large. Only the edge is obtained. If it is exceeded, only the edge is obtained.
If ($ page> $ allPageCount-floor ($ pageCountLength/2 )){
For ($ I =-$ pageCountLength; $ I <0; $ I ++ ){
$ Arr [] = array ('page' => $ allPageCount + $ I + 1 );
}
Return $ arr;
}
// The number in the middle.
For ($ I =-$ halfLength; $ I <$ pageCountLength-$ halfLength; $ I ++ ){
$ Arr [] = array ('page' => $ page + $ I );
}
Return $ arr;
}
}
