php自定义分页类完整实例

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 $subPage_type;//显示分页的类型/*  当@subPage_type=1的时候为普通分页模式     example：  共4523条记录,每页显示10条,当前第1/453页 [首页] [上页] [下页] [尾页]     当@subPage_type=2的时候为经典分页样式     example：  当前第1/453页 [首页] [上页] 1 2 3 4 5 6 7 8 9 10 [下页] [尾页] */ function __construct($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 /* 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;$i<count($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;  } /*  构造普通模式的分页  共4523条记录,每页显示10条,当前第1/453页 [首页] [上页] [下页] [尾页]  */ 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  } /*  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="";  $subPageCss2Str.="当前第".$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>'; }*/?>
