php自练项目之数字与文字的分页效果在函数中实现
/** *  * @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) || $_page < 0 || !is_numeric($_page)) {            $_page = 1;        } else {            $_page = intval($_page);        }    } else {        $_page = 1;    }    $_pagesize = $_size;    $_num = _num_rows(_query($_sql));    if ($_num == 0) {        $_pageabsolute = 1;    } else {        $_pageabsolute = ceil($_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);?>
