PHP实现可自定义样式的分页类

本文实例为大家分享了PHP实现可自定义样式的分页类，供大家参考，具体内容如下

ShowPage = $ShowPage;
 $this->CountPage  = ceil ( $CountNum / $PageSize );
 $this->Floorp  = floor ( $ShowPage / 2 ); // 偏移量 
 $this->PageClass  = is_null ( $PageClass ) ? '' : $PageClass;
 $this->CurClass = is_null ( $CurClass ) ? '' : $CurClass;
  
 // $ServerURL  = ( preg_match('/?/i', $_SERVER['REQUEST_URI']))?preg_replace('/&p=[0-9]+/i', "", $_SERVER['REQUEST_URI']) : $_SERVER['REQUEST_URI']."?";
 // if( substr($ButURL,0,2)=='//' ){
  // $ServerURL  = substr($ServerURL,1);
 // }
 // $url   = preg_replace('/p=[d]*/i', '', $ServerURL);
  $url   = '';
 //推荐自己传url,不传也可以打开上面的代码自动获取
 $this->PageUrl  = is_null ( $PageUrl ) ? $url : $PageUrl;
 }
 
 
 public function getPage($Page = 1, $ShowToPage = true, $Html = null) {
 $StartPage  = ($Page - $this->Floorp); // 开始页码
 $EndPage  = ($Page + $this->Floorp); // 结束页码
  
 if ($this->CountPage < $this->ShowPage) {
  $StartPage = 1;
  $EndPage = $this->CountPage;
 }
  
 if ($StartPage < 1) {
  $StartPage = 1;
  $EndPage = $this->ShowPage;
 }
  
 if ($EndPage > $this->CountPage) {
  $StartPage = $this->CountPage - $this->ShowPage + 1;
  $EndPage = $this->CountPage;
 }
  
 $PageHtml = '';
  
 if (! is_null ( $Html )) {
  if ($Html == 'li') {
  $Shtml = '
';
  $Ehtml = '
';
  } else {
  $Shtml = '
';
  $Ehtml = '
';
  }
 }
  
 if (true == $ShowToPage) {
  $PageHtml  .= "$ShtmlPageUrl}p=1'>« 首页$Ehtml";
  $PrveUrl   = $this->getPrve($Page);
  $PageHtml  .= "$Shtml« 上一页$Ehtml";
 }
  
 for($i = $StartPage; $i <= $EndPage; $i ++) {
  if ($Page == $i) {
  $PageHtml  .= "$ShtmlPageUrl}p={$i}' class='{$this->CurClass}'>{$i}$Ehtml";
  } else {
  $PageHtml  .= "$ShtmlPageUrl}p={$i}' class='{$this->PageClass}'>{$i}$Ehtml";
  }
 }
  
 if (true == $ShowToPage) {
  $NextUrl   = $this->getNext($Page);
  $PageHtml  .= "$Shtml下一页 »$Ehtml";
  $PageHtml  .= "$ShtmlPageUrl}p={$this->CountPage}' >尾页 »$Ehtml";
 }
  
 return $PageHtml;
 }
 
 public function getPrve($Page){
 if ($Page != 1) {
  $Prve  = $Page - 1;
  $PrveUrl  = "{$this->PageUrl}p={$Prve}";
 } else {
  $PrveUrl  = "{$this->PageUrl}p=1";
 }
  
 return $PrveUrl;
 }
 
 public function getNext($Page){
 if ($Page != $this->CountPage) {
  $Next  = $Page + 1;
  $NextUrl  = "{$this->PageUrl}p={$Next}";
 } else {
  $NextUrl  = "{$this->PageUrl}p={$this->CountPage}";
 }
  
 return $NextUrl;
 }
 
 
 
}

再为大家分享一个主要用于新手学习php分页，代码简单实用，主要是注释很完整。

1. Page.class.php

count=$count;
  $this->showPages=$showPages;
  $this->currPage=$currPage;
  $this->subPages=$subPages;
   
  //如果链接没有设置则获取当前连接
  if(empty($href)){
   $this->href=htmlentities($_SERVER['PHP_SELF']); 
  }else{
   $this->href=$href;
  }
  $this->construct_Pages();
 }
 
 
 public function getPages(){
  return $this->page_arr;
 }
 
 
 public function showPages($style=1){
  $func='pageStyle'.$style;
  return $this->$func();
 }
 
 
 protected function pageStyle1(){
  
  $pageStr='共'.$this->count.'条记录，每页显示'.$this->subPages.'条';
  $pageStr.='当前第'.$this->currPage.'/'.$this->countPages.'页 ';
 
  $_GET['page'] = 1;
  $pageStr.='[href.'?'.http_build_query($_GET).'">首页] ';
  //如果当前页不是第一页就显示上页
  if($this->currPage>1){
   $_GET['page'] = $this->currPage-1;
   $pageStr.='[href.'?'.http_build_query($_GET).'">上页] ';
  }
 
  foreach ($this->page_arr as $k => $v) {
   $_GET['page'] = $k;
   $pageStr.='['.$k.'] ';
  }
 
  //如果当前页小于总页数就显示下一页
  if($this->currPage<$this->countPages){
   $_GET['page'] = $this->currPage+1;
   $pageStr.='[href.'?'.http_build_query($_GET).'">下页] ';
  }
 
  $_GET['page'] = $this->countPages;
  $pageStr.='[href.'?'.http_build_query($_GET).'">尾页] ';
 
  return $pageStr;
 }
 
 
 protected function construct_Pages(){
  //计算总页数
  $this->countPages=ceil($this->count/$this->subPages);
  //根据当前页计算前后页数
  $leftPage_num=floor($this->showPages/2);
  $rightPage_num=$this->showPages-$leftPage_num;
 
  //左边显示数为当前页减左边该显示的数 例如总显示7页 当前页是5 左边最小为5-3 右边为5+3
  $left=$this->currPage-$leftPage_num;
  $left=max($left,1); //左边最小不能小于1
  $right=$left+$this->showPages-1; //左边加显示页数减1就是右边显示数
  $right=min($right,$this->countPages); //右边最大不能大于总页数
  $left=max($right-$this->showPages+1,1); //确定右边再计算左边，必须二次计算
   
  for ($i=$left; $i <= $right; $i++) {
   $_GET['page'] = $i;
   $this->page_arr[$i]=$this->href.'?'.http_build_query($_GET);
  }
 }
}

2. demo.php 

";
print_r($p->getPages()); 
 
//生成一个页码样式（可添加自定义样式）
//样式 共45条记录,每页显示10条,当前第1/4页 [首页] [上页] [1] [2] [3] .. [下页] [尾页]
echo $p->showPages(1); 

以上就是本文的全部内容，希望对大家学习PHP程序设计有所帮助。
