本文实例讲述了php自定义分页类。分享给大家供大家参考，具体如下：

<?phpheader("Content-type:text/html;Charset=utf-8");class SubPages{ private $each_disNums;//每页显示的条目数 private $nums;//总条目数 private $current_page;//当前被选中的页 private $sub_pages;//每次显示的页数 private $pageNums;//总页数 private $page_array = array();//用来构造分页的数组 private $subPage_link;//每个分页的链接 //private $subPage_type;//显示分页的类型 function __construct($each_disNums,$nums,$current_page,$sub_pages,$subPage_link){ $this->each_disNums=intval($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; // $this->show_SubPages($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 //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 $this->page_array; } function construct_num_Page(){ if($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;$i<count($current_array);$i++){ $current_array[$i]=$i+1; } }else if ($this->current_page <= $this->pageNums && $this->current_page > $this->pageNums - $this->sub_pages + 1 ){ for($i=0;$i<count($current_array);$i++){ $current_array[$i]=($this->pageNums)-($this->sub_pages)+1+$i; } }else{ for($i=0;$i<count($current_array);$i++){ $current_array[$i]=$this->current_page-2+$i; } } } return $current_array; } function subPageCss1(){ $subPageCss1Str=""; $subPageCss1Str.="共".$this->nums."条记录，"; $subPageCss1Str.="每页显示".$this->each_disNums."条，"; $subPageCss1Str.="当前第".$this->current_page."/".$this->pageNums."页 "; if($this->current_page > 1){ $firstPageUrl=$this->subPage_link."1"; $prewPageUrl=$this->subPage_link.($this->current_page-1); $subPageCss1Str.="[<a href='$firstPageUrl'>首页</a>] "; $subPageCss1Str.="[<a href='$prewPageUrl'>上一页</a>] "; }else { $subPageCss1Str.="[首页] "; $subPageCss1Str.="[上一页] "; } if($this->current_page < $this->pageNums){ $lastPageUrl=$this->subPage_link.$this->pageNums; $nextPageUrl=$this->subPage_link.($this->current_page+1); $subPageCss1Str.=" [<a href='$nextPageUrl'>下一页</a>] "; $subPageCss1Str.="[<a href='$lastPageUrl'>尾页</a>] "; }else { $subPageCss1Str.="[下一页] "; $subPageCss1Str.="[尾页]"; } return $subPageCss1Str; //在此可以设置显示的CSS样式 } function subPageCss2(){ $subPageCss2Str=""; $subPageCss2Str.="当前第".$this->current_page."/".$this->pageNums."页 "; if($this->current_page > 1){ $firstPageUrl=$this->subPage_link."1"; $prewPageUrl=$this->subPage_link.($this->current_page-1); $subPageCss2Str.="[<a href='$firstPageUrl'>首页</a>] "; $subPageCss2Str.="[<a href='$prewPageUrl'>上一页</a>] "; }else { $subPageCss2Str.="[首页] "; $subPageCss2Str.="[上一页] "; } $a=$this->construct_num_Page(); for($i=0;$i<count($a);$i++){ $s=$a[$i]; if($s == $this->current_page ){ $subPageCss2Str.="[<span style='color:red;font-weight:bold;'>".$s."</span>]"; }else{ $url=$this->subPage_link.$s; $subPageCss2Str.="[<a href='$url'>".$s."</a>]"; } } if($this->current_page < $this->pageNums){ $lastPageUrl=$this->subPage_link.$this->pageNums; $nextPageUrl=$this->subPage_link.($this->current_page+1); $subPageCss2Str.=" [<a href='$nextPageUrl'>下一页</a>] "; $subPageCss2Str.="[<a href='$lastPageUrl'>尾页</a>] "; }else { $subPageCss2Str.="[下一页] "; $subPageCss2Str.="[尾页] "; } return $subPageCss2Str; }}//使用如下/*include('../mysql.php');//每页显示的条数 $page_size=3;//总条目数$sql=mysql_query("select * from `stu_info`");$nums=mysql_num_rows($sql);//每次显示的页数 $sub_pages=10;//得到当前是第几页 if(!isset($_GET["p"])){ $pageCurrent=1; }else{ $pageCurrent=$_GET["p"]; } $subPages=new SubPages($page_size,$nums,$pageCurrent,$sub_pages,"page.php?p="); $page=$subPages->subPageCss2(); echo $page;//在此可以设置CSS样式 $ss=mysql_query("select * from `stu_info` limit ".$page_size*($pageCurrent-1).",".$page_size); while($row=mysql_fetch_array($ss)){ echo $row['stunum'].''.$row['stuname'].''.$row['clanum'].'<br>'; }*/?>
