PHP簡易分頁類

這是一個簡單易用的分頁類。只需在你原有的程式中加兩句、改一句就可以了
先貼代碼
paging.php

PHP code

<?phpclass Paging {  public static $count = 0;  public static $size = 0;  public static $page = 0;  static function prepare($sql, $pagesize=10) {    $page = isset($_GET['page']) ? $_GET['page'] : 1;    $pageon = ($page - 1) * $pagesize;    $sql = preg_replace('/select\s/i', '$0SQL_CALC_FOUND_ROWS ', $sql) . " limit $pageon, $pagesize";    $rs = mysql_query($sql);    $p = mysql_query('SELECT FOUND_ROWS()');    list(self::$count) = mysql_fetch_row($p);    self::$size = $pagesize;    self::$page = $page;    return $rs;  }  static function bar($tpl='') {    if(!$tpl) $tpl = '<a href=?reset>首頁</a> <a href=?prve>上一頁</a> <a href=?next>下一頁</a> <a href=?end>尾頁</a>';    $count = ceil(self::$count / self::$size);    $page = self::$page;    unset($_GET['page']);    $d = array(      'reset' => 1,      'prve' => $page > 1 ? $page - 1 : 1,      'next' => $page < $count ? $page + 1 : $count,      'end' => $count,    );    foreach($d as $k=>$v) {      $_GET['page'] = $v;      $tpl = str_replace($k, http_build_query($_GET), $tpl);    }    echo $tpl;  }}

通常你都有類似這樣的語句 $sql ="....."; $rs = mysql_query($sql); 或 $rs = mysql_query("select ...."); 你只需改作 include 'paging.php'; $rs = paging::prepare($sql, 每頁行數); 在需要出現分頁條的地方寫入 paging::bar(); 就可以了，非常簡單！
