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)); ( empty empty ( $this ->currentpage))? $this ->currentpage=1: $this ->currentpage= $this ->currentpage; $this ->pagesize= ceil ( abs (@ $pagesize +0)); ( empty empty ( $this ->pagesize))? $this ->pagesize=5: $this ->pagesize= $this ->pagesize; $this ->leftoffset= ceil ( abs (@ $leftoffset +0)); ( empty empty ( $this ->leftoffset))? $this ->leftoffset=2: $this ->leftoffset= $this ->leftoffset; $this ->rightoffset= ceil ( abs (@ $rightoffset +0)); ( empty empty ( $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 ){ if (! $sql ||! $conn ){ echo "参数传递错误" ; return false;} $this ->sqlquery=mysql_query( $sql , $conn ); if (! $this ->sqlquery){ echo "执行sql语句失败" ; return false;} } function recordset(){ return mysql_fetch_array( $this ->sqlquery); } //取得模板内容 function gettemplate( $filedir ){ if ( file_exists ( $filedir )){ $f = fopen ( $filedir , "r" ); $this ->template= fread ( $f , filesize ( $filedir )); } else { echo "获取模板文件失败...文件不存在" ; exit (); } //取得区块内容 $start = strpos ( $this ->template, "<!--templatebegin-->" ); $end = strpos ( $this ->template, "<!--templateend-->" ); $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; } //设定默认标签对应值 function setdefaulttagvalue(){ $this ->tagitems[ "previouspage" ]= "上一页" ; $this ->tagitems[ "previouspagelink" ]= "<a href='{link}'>上一页</a>" ; $this ->tagitems[ "previoustenpage" ]= "上十页" ; $this ->tagitems[ "previoustenpagelink" ]= "<a href='{link}'>上十页</a>" ; $this ->tagitems[ "nextpage" ]= "下一页" ; $this ->tagitems[ "nextpagelink" ]= "<a href='{link}'>下一页</a>" ; $this ->tagitems[ "nexttenpage" ]= "下十页" ; $this ->tagitems[ "nexttenpagelink" ]= "<a href='{link}'>下十页</a>" ; $this ->tagitems[ "firstpage" ]= "首页" ; $this ->tagitems[ "firstpagelink" ]= "<a href='{link}'>首页</a>" ; $this ->tagitems[ "lastpage" ]= "尾页" ; $this ->tagitems[ "lastpagelink" ]= "<a href='{link}'>尾页</a>" ; $this ->tagitems[ "listpage" ]= "[{list}]" ; $this ->tagitems[ "listpagelink" ]= "<a href='{link}'>[{list}]</a>" ; //定义模板标签 $this ->tagvalues[ "previouspage" ]= "{previouspage}" ; $this ->tagvalues[ "previouspagelink" ]= "{previouspage}" ; $this ->tagvalues[ "previoustenpage" ]= "{previoustenpage}" ; $this ->tagvalues[ "previoustenpagelink" ]= "{previoustenpage}" ; $this ->tagvalues[ "nextpage" ]= "{nextpage}" ; $this ->tagvalues[ "nextpagelink" ]= "{nextpage}" ; $this ->tagvalues[ "nexttenpage" ]= "{nexttenpage}" ; $this ->tagvalues[ "nexttenpagelink" ]= "{nexttenpage}" ; $this ->tagvalues[ "firstpage" ]= "{firstpage}" ; $this ->tagvalues[ "firstpagelink" ]= "{firstpage}" ; $this ->tagvalues[ "lastpage" ]= "{lastpage}" ; $this ->tagvalues[ "lastpagelink" ]= "{lastpage}" ; $this ->tagvalues[ "listpage" ]= "{list}" ; $this ->tagvalues[ "listpagelink" ]= "{list}" ; /*其他标签直接替换 {$datacount}:共{$datacount}条记录 {$currentpage}:当前为第{$currentpage}页 {$totalpage}:共{$totalpage}页 {$numperpage}:每页{$numperpage}条 */ } // 重新设定标签对应值 function settagvalue( $item , $itemvalue = "" , $value = "" ){ if (!isset( $item )||!isset( $itemvalue )||!isset( $value )){ return ;} foreach ( $this ->tagitems as $key => $v ){ if ( $key == $item ){ ( empty empty ( $itemvalue ))?
