又一款php分頁類代碼

代碼如下

複製代碼

class multipage {  var $total;  var $perpage;  var $pages;  var $maxpage;  var $offset = 9;  var $curr_page;    function init($total, $perpage, $maxpage) { //初始化頁數   $this->total;   $this->perpage;   $this->maxpage;   $this->offset = 9;  }    function getpagelist() {//擷取分頁列表   $result_pages = "";   $this->pages = ceil($this->total / $this->perpage);      if ($this->pages > $this->maxpage) {    $from = $this->curr_page - $this->offset;    if ($from < 1) {     $from = 1;    }    $to = $from + $this->maxpage - 1;    if ($to > $this->pages) {     $to = $this->pages;     if (($to - $from) < $this->maxpage) {      $from = $from - 1;     }    }   } else {    $from = 1;    $to = $this->pages;   }      $p = 0;   for($i = $from; $i <= $to; $i++) {    $result_pages[$p] = $i;    $p++;   }      return $result_pages;  }    function getfirst() { //擷取第一頁   if ($this->curr_page > 1 && $this->pages > 1) {    return 1;   } else {    return "";   }  }    function getlast() { //取末頁   if ($this->pages > 1 && $this->curr_page < $this->pages) {    return $this->pages;   } else {    return "";   }  }    function getprev() {//上一頁   $prevpage = $this->curr_page - 1;   if ($prevpage > 0) {    return $prevpage;   } else {    $prevpage = "";    return $prevpage;   }  }    function getnext() {//下一頁   $nextpage = $this->curr_page + 1;   if ($nextpage <= $this->pages) {    return $nextpage;   } else {    $nextpage = "";    return $nextpage;   }  }    function gettotal() {//共多少頁   if ($this->pages > 0) {    return $this->pages;   } else {    return 1;   }  }   } //分頁類的使用方法 $page = new multipage(); $page->gettotal(); //總頁婁 $page->getnext();//下一頁
