php利用模板分页程序
这是一款比较经典的php分页代码,利用了程序模板,页面分离的方式来做这个文件分页功能,实在是太牛了,实例代码如下.
page.class.php:
- class page{
- var $currentpage;
- var $leftoffset;
- var $rightoffset;
- var $totalpage;//总页数
- var $recordcount;//总记录数
- var $pagesize;//每页显示条数
- var $pageurl;
- var $hypelink;
- var $template;
- var $tpl;
- var $tagitems=array();
- var $tagvalues=array();
- var $sqlquery;
- //构造函数
- function page($currentpage=1,$pagesize=5,$leftoffset=2,$rightoffset=7,$pageurl="?page="){
- echo "分页类开始";
- $this->currentpage=ceil(abs(@$currentpage+0));
- (emptyempty($this->currentpage))?$this->currentpage=1:$this->currentpage=$this->currentpage;
- $this->pagesize=ceil(abs(@$pagesize+0));
- (emptyempty($this->pagesize))?$this->pagesize=5:$this->pagesize=$this->pagesize;
- $this->leftoffset=ceil(abs(@$leftoffset+0));
- (emptyempty($this->leftoffset))?$this->leftoffset=2:$this->leftoffset=$this->leftoffset;
- $this->rightoffset=ceil(abs(@$rightoffset+0));
- (emptyempty($this->rightoffset))?$this->rightoffset=7:$this->rightoffset=$this->rightoffset;
- $this->pageurl=$pageurl;
- $this->setdefaulttagvalue();
- }
- //取得记录总数
- //$sql="select count(id) as n from table";
- function getrecordcount($sql,$conn){
- $query=@mysql教程_query($sql,$conn);
- if(!$query){echo "执行sql语句失败";exit();}
- while($rs=mysql_fetch_row($query)){
- $this->recordcount=$rs[0];//取得记录总数
- }
- $this->totalpage=ceil($this->recordcount / $this->pagesize);//计算总页数
- if($this->currentpage > $this->totalpage){$this->currentpage=$this->totalpage;}//判断当前页是否大于总页数
- mysql_free_result($query);
- }
- //select * from tb p->setlimit();
- function setlimit(){
- $limit="limit ".($this->currentpage-1)*$this->pagesize;
- $limit.=",$this->pagesize";
- return $limit;
- }
- function executesql($sql,$conn){

- $this->tpl=substr($this->template,$start+strlen("<!--templatebegin-->"),$end-$start-strlen("<!--templateend-->")-2);
- if($this->tpl==""){echo "模板内容为空,请检查标签设置是否正确。";exit();}
- //echo $this->tpl;
- }
