PHP自练项目之数字与文字的分页效果在函数中实现

时间:2015-07-25 编辑:Doctor.chen 来源:CnBlogs

/** * * @param $_sql * @param $_size */ function _page($_sql,$_size) { //将里面的所有变量取出来,外部可以访问 global $_page,$_pagesize,$_pagenum,$_pageabsolute,$_num; if (isset($_GET['page'])) { $_page = $_GET['page']; if (empty($_page) || $_page < 0 || !($_page)) { $_page = 1; } else { $_page = ($_page); } } else { $_page = 1; } $_pagesize = $_size; $_num = _num_rows(_query($_sql)); if ($_num == 0) { $_pageabsolute = 1; } else { $_pageabsolute = ($_num / $_pagesize); } if ($_page > $_pageabsolute) { $_page = $_pageabsolute; } $_pagenum = ($_page - 1) * $_pagesize; } /** * _paging分页函数 * @param $_type * @return 返回分页 */ function _paging($_type) { global $_page,$_pageabsolute,$_num; if ($_type == 1) { echo '<div id="page_num">'; echo '<ul>'; for ($i=0;$i<$_pageabsolute;$i++) { if ($_page == ($i+1)) { echo '<li><a href="blog.PHP?page='.($i+1).'" class="selected">'.($i+1).'</a></li>'; } else { echo '<li><a href="blog.php?page='.($i+1).'">'.($i+1).'</a></li>'; } } echo '</ul>'; echo '</div>'; } elseif ($_type == 2) { echo '<div id="page_text">'; echo '<ul>'; echo '<li>'.$_page.'/'.$_pageabsolute.'页 | </li>'; echo '<li>共有<strong>'.$_num.'</strong>个会员 | </li>'; if ($_page == 1) { echo '<li>首页 | </li>'; echo '<li>上一页 | </li>'; } else { echo '<li><a href="'.SCRIPT.'.php">首页</a> | </li>'; echo '<li><a href="'.SCRIPT.'.php?page='.($_page-1).'">上一页</a> | </li>'; } if ($_page == $_pageabsolute) { echo '<li>下一页 | </li>'; echo '<li>尾页</li>'; } else { echo '<li><a href="'.SCRIPT.'.php?page='.($_page+1).'">下一页</a> | </li>'; echo '<li><a href="'.SCRIPT.'.php?page='.$_pageabsolute.'">尾页</a></li>'; } echo '</ul>'; echo '</div>'; } }

在核心函数库包装以上代码glob.funic.php

然后只要在文件中调用以下函数就行:

<?php }
//_pageing函数调用分页,1|2,1表示数字分页,2表示文本分页
_paging(2);
?>
