本篇文章主要介绍php自定义分页类的原理，感兴趣的朋友参考下，希望对大家有所帮助。
代码如下：
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;
// $this->show_SubPages($subPage_type);
}
// show_SubPages函数用在构造函数里面。而且用来判断显示什么样子的分页
/* function show_SubPages($subPage_type){
if($subPage_type == 1){
$this->subPageCss1();
}else if ($subPage_type == 2){
$this->subPageCss2();
}
}
*/
//用来给建立分页的数组初始化的函数。
function initArray(){
for($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;$icurrent_page <= $this->pageNums && $this->current_page > $this->pageNums - $this->sub_pages + 1 ){
for($i=0;$ipageNums)-($this->sub_pages)+1+$i;
}
}else{
for($i=0;$icurrent_page-2+$i;
}
}
}
return $current_array;
}
/*
