class SubPages{
private $each_disNums; //The number of entries displayed on each page
private $nums; //Total number of entries
private $current_page; //The currently selected page
private $sub_pages;//Number of pages displayed each time
private $pageNums;//Total number of pages
private $point;//Total number of pages
private $page_array = array();//Array used to construct paging
private $subPage_link;//The link of each page
private $subPage_type;//Display the type of page

__construct is the constructor of SubPages, which is used to run automatically when creating the class.
@$each_disNums Displayed on each page Number of entries
@nums Total number of entries
@current_num Currently selected page
@sub_pages Number of pages displayed each time
@subPage_link Link to each page
@subPage_type Display type of paging
When @subPage_type=1 Normal paging mode
example: 4523 records in total, 10 records displayed on each page, current page 1/453 [Home] [Previous page] [Next page] [Last page]
When @subPage_type=2, it is the classic paging style
example: Current page 1/453 [Home page] [Previous page] 1 2 3 4 5 6 7 8 9 10 [Next page] [Last page]
* /
function __construct($each_disNums,$nums,$current_page, $sub_pages,$subPage_link,$subPage_type,$point){
$this->each_disNums=intval($each_disNums);
$this->nums=intval($nums);
if(!$current_page){
$this->current_page=1;
}else{
$this->current_page=intval($current_page);
}
$this->sub_pages=intval($sub_pages);
$this->pageNums =ceil($nums/$each_disNums);
$this->subPage_link=$subPage_link;
$this->point=$point;
$this->show_SubPages($subPage_type);
//echo $this ->pageNums."--".$this->sub_pages;
}
/ *
__destruct destructor, called when the class is no longer in use, this function is used to release resources.
* /
function __destruct(){
unset($each_disNums);
unset($nums);
unset($current_page);
unset($sub_pages);
unset($pageNums);
unset($page_array) ;
unset($subPage_link);
unset($subPage_type);
}
/ *
show_SubPages function is used in the constructor. And used to determine what kind of paging to display
* /
function show_SubPages($subPage_type){
if($subPage_type == 1){
$this->subPageCss1();
}elseif ($subPage_type == 2) {
$this->subPageCss2();
}
}
/ *
Function used to initialize the array for creating paging.
* /
function initArray(){
for($i=0;$i<$this->sub_pages;$i++){
$this->page_array[$i]=$i;
}
return $this->page_array;
}
/ *
construct_num_Page该函数使用来构造显示的条目
即使：[1][2][3][4][5][6][7][8][9][10]
* /
function construct_num_Page(){
if($this->pageNums < $this->sub_pages){
$current_array=array();
for($i=0;$i<$this->pageNums;$i++){
$current_array[$i]=$i+1;
}
}else{
$current_array=$this->initArray();
if($this->current_page <= 3){
for($i=0;$i $current_array[$i]=$i+1;
}
}elseif ($this->current_page <= $this->pageNums && $this->current_page > $this->pageNums - $this->sub_pages + 1 ){
for($i=0;$i $current_array[$i]=($this->pageNums)-($this->sub_pages)+1+$i;
}
}else{
for($i=0;$i $current_array[$i]=$this->current_page-2+$i;
}
}
}
return $current_array;
}
/ *
构造经典模式的分页
当前第1/453页 [首页] [上页] 1 2 3 4 5 6 7 8 9 10 [下页] [尾页]
* /
function subPageCss2(){
$subPageCss2Str="";
//共246页2347条商家信息
$subPageCss2Str.= "当前第".$this->current_page." /".$this->pageNums." 页共".$this->nums."条商家信息";
//$subPageCss2Str.="当前第".$this->current_page."/".$this->pageNums."页 ";
if($this->current_page > 1){
$firstPageUrl=$this->subPage_link."1"."#zkfb_shop";
$prewPageUrl=$this->subPage_link.($this->current_page-1).$this->point;
//首页上一页
$subPageCss2Str.="首页";
