一個簡單的php分頁小模塊

<?php
$str=pagestr("http:www.abc.com?",195,11,10,8);
print($str);
//url連接全度，countdatas表數(shù)據(jù)總行數(shù)妖泄，currentpage第幾頁（0是第一頁）坐漏，everpage每頁多少行,beforlaterln前后長度
function pagestr($url,$countdatas,$currentpage=0,$everpage=10,$beforlaterln=5){
    $page="";
    $intpart=$countdatas/$everpage;
    $remainderpart=$countdatas%$everpage;//余數(shù)
    $countpage=floor($intpart);//取整數(shù)
    $currentpage = $currentpage<0 ? 0:$currentpage;
    if($remainderpart==0){//余數(shù)判斷
        $currentpage=$currentpage>$countpage-1?$countpage-1:$currentpage;
        $countpage;//總頁數(shù)
        $pp=$currentpage+1;
        $strbe="";
        $pagebefore=$pp-$beforlaterln-1;
        for($i=$pp; $i > $pagebefore; $i--){ 
            if($i>0 && $i<$pp){
                $strbe="<a class='num' href='".$url."&p=".($i-1)."'>".$i."</a>".$strbe;
            }
        }
        if($pp<=1){$strbe="";}else{$strbe="<a class='num' href='".$url."&p=0'>首頁</a>"."<a class='num' href='".$url."&p=".($pp-2)."'>上一頁</a>".$strbe;}
        $strmid="<span class='current'>".$pp."</span>";
        $strlater="";
        $pagelater=$pp+$beforlaterln;
        for($i=$pp; $i < $pagelater; $i++){ 
            if($i<$countpage){
                $strlater.="<a class='num' href='".$url."&p=".($i)."'>".($i+1)."</a>";
            }
        }
        if($pp>=$countpage){}else{$strlater.="<a class='num' href='".$url."&p=".$pp."'>下一頁</a>"."<a class='num' href='".$url."&p=".($countpage-1)."'>尾頁</a>";}
        $page=$strbe.$strmid.$strlater;
    }else{
        $countpage+=1;//總頁數(shù)
        $currentpage=$currentpage>$countpage-1?$countpage-1:$currentpage;
        $pp=$currentpage+1;
        $strbe="";
        $pagebefore=$pp-$beforlaterln-1;
        for($i=$pp; $i > $pagebefore; $i--){ 
            if($i>0 && $i<$pp){
                $strbe="<a class='num' href='".$url."&p=".($i-1)."'>".$i."</a>".$strbe;
            }
        }
        if($pp<=1){$strbe="";}else{$strbe="<a class='num' href='".$url."&p=0'>首頁</a>"."<a class='num' href='".$url."&p=".($pp-2)."'>上一頁</a>".$strbe;}
        $strmid="<span class='current'>".$pp."</span>";
        $strlater="";
        $pagelater=$pp+$beforlaterln;
        for($i=$pp; $i < $pagelater; $i++){
            if($i<$countpage){
                $strlater.="<a class='num' href='".$url."&p=".($i)."'>".($i+1)."</a>";
            }
        }
        if($pp>=$countpage){}else{$strlater.="<a class='num' href='".$url."&p=".$pp."'>下一頁</a>"."<a class='num' href='".$url."&p=".($countpage-1)."'>尾頁</a>";}
        $page=$strbe.$strmid.$strlater;
    }
    return "共".$countpage."頁".$page;
}
?>

運行后得到一下字符串

共20頁<a class='num' >首頁</a>
<a class='num' >上一頁</a>
<a class='num' >4</a>
<a class='num' >5</a>
<a class='num' >6</a>
<a class='num' >7</a>
<a class='num' >8</a>
<a class='num' >9</a>
<a class='num' >10</a>
<a class='num' >11</a>
<span class='current'>12</span>
<a class='num' >13</a>
<a class='num' >14</a>
<a class='num' >15</a>
<a class='num' >16</a>
<a class='num' >17</a>
<a class='num' >18</a>
<a class='num' >19</a>
<a class='num' >20</a>
<a class='num' >下一頁</a>
<a class='num' >尾頁</a>

希望對大家有幫助，謝謝！
