简易分页类
这是一个简单易用的分页类。只需在你原有的程序中加两句、改一句就可以了
先贴代码
paging.php

<?php<br />
class Paging {<br />
  public static $count = 0;<br />
  public static $size = 0;<br />
  public static $page = 0;<br />
  static function prepare($sql, $pagesize=10) {<br />
    $page = isset($_GET['page']) ? $_GET['page'] : 1;<br />
    $pageon = ($page - 1) * $pagesize;<br />
    $sql = preg_replace('/select\s/i', '$0SQL_CALC_FOUND_ROWS ', $sql) . " limit $pageon, $pagesize";<br />
    $rs = mysql_query($sql);<br />
    $p = mysql_query('SELECT FOUND_ROWS()');<br />
    list(self::$count) = mysql_fetch_row($p);<br />
    self::$size = $pagesize;<br />
    self::$page = $page;<br />
    return $rs;<br />
  }<br />
  static function bar($tpl='') {<br />
    if(!$tpl) $tpl = '<a href=?reset>首页</a> <a href=?prve>上一页</a> <a href=?next>下一页</a> <a href=?end>尾页</a>';<br />
    $count = ceil(self::$count / self::$size);<br />
    $page = self::$page;<br />
    unset($_GET['page']);<br />
    $d = array(<br />
      'reset' => 1,<br />
      'prve' => $page > 1 ? $page - 1 : 1,<br />
      'next' => $page < $count ? $page + 1 : $count,<br />
      'end' => $count,<br />
    );<br />
    foreach($d as $k=>$v) {<br />
      $_GET['page'] = $v;<br />
      $tpl = str_replace($k, http_build_query($_GET), $tpl);<br />
    }<br />
    echo $tpl;<br />
  }<br />
}<br />
Copy after login

通常你都有类似这样的语句
$sql =".....";
$rs = mysql_query($sql);

$rs = mysql_query("select ....");


你只需改作
include 'paging.php';
$rs = paging::prepare($sql, 每页行数);
在需要出现分页条的地方写入
paging::bar();

就可以了,非常简单!


------解决方案--------------------
前排拜模。
这样的写法还是第一次见到。
 $sql = preg_replace('/select\s/i', '$0SQL_CALC_FOUND_ROWS ', $sql) . " limit $pageon, $pagesize";

sql还用preg_replace……

谢谢分享,确实很方便  ,简单易用 。学习了。
