分享一個自己常用的php分頁函數，大家可以收藏以后方便使用，代碼如下：

/**

* @author maijiawei <632157268@qq.com>

* @param int $total 總數

* @param int $num 顯示數量

* @param int $page 當前頁碼

* @param string $url URL demo:index.php?page=

* @param string $anchor 描 demo:#comment

* @return string 頁碼html

*/

function pagination($total, $num, $page, $url, $anchor = '') {

$page_show_num = 5; //顯示數量

$page_total = @ceil($total / $num); //總頁數

if($page_total<=1){

return '';

}

$page_arr = array(); //頁碼以數組保存

$html = '';

//上頁

if($page<=1){

$html .= "<span class=/"page_pre/">上頁</span>";

}else{

$page_pre = $page-1;

$html .= "<a class=/"page_pre/" href=/"$url$page_pre$anchor/">上頁</a>";

}

$left_num = @ceil($page_show_num / 2); //左邊顯示數量
$check_num = 0;

for($i=1;$i<=$left_num;$i++){ //獲取左邊頁碼

$p = $page-$i;

if($p>0){

$page_arr[]=$p;

$check_num++;

}

}

$left_not_num = $left_num-$check_num; //如果當前頁碼是1,左邊頁碼是3,那么還有2個頁碼未獲得,右邊的頁碼就加上2

$right_num = $page_show_num-$left_num+$left_not_num; //右邊顯示數量
