PHP将Excel导入数据库以及数据库数据导出至Excel，excel数据导出

一.导入

　　导入需要使用能读取Excel的组件，网上也有比较好的组件，这里分享我使用的：下载  提取码：vxyn。(注意两个文件有引用关系)

<?<span>php
</span><span>//</span><span>传入要导入的Excel的文件名</span>
<span>function</span> import_to_DB(<span>$filename</span><span>) {
    </span><span>require_once</span>'reader.php'<span>;
    </span><span>$data</span> = <span>new</span> Spreadsheet_Excel_Reader();     <span>//</span><span>创建读取Excel的对象</span>
    <span>$data</span>->setOutputEncoding('utf-8');    <span>//</span><span>设置读取Excel内容后输出的字符编码</span>
    <span>$data</span>->read("data/Excel/{<span>$filename</span>}.xls"<span>);
    </span><span>$db</span> = <span>mysql_connect</span>('localhost', '用户名', '密码') or <span>die</span>("Could not connect to database."); <span>//</span><span>连接数据库   </span>
    <span>mysql_query</span>("set names 'uft8'"); <span>//</span><span>输出中文   </span>
    <span>mysql_select_db</span>('数据库名'); <span>//</span><span>选择数据库   </span>
    <span>error_reporting</span>(<span>E_ALL</span> ^ <span>E_NOTICE</span><span>);
    </span><span>for</span> (<span>$i</span> = 1; <span>$i</span> <= <span>$data</span>->sheets[0]['numRows']; <span>$i</span>++<span>) {
        </span><span>echo</span> <span>$data</span>->sheets[0]['cells'][<span>$i</span><span>][列数];
        </span><span>//</span><span>这里可以把每一行相应列的值插到数据库中，如：</span>
        <span>/*</span><span>
        $sql="insert "表名" values(对应项...)";
        mysql_query($sql);
        可加上错误判断
        </span><span>*/</span><span> 
    }  
</span>?>        

总之，能够读出表格中每一行中的相应列$data->sheets[0][行][列]的值，插入操作就好办了。

二.导出

　　导出可以利用MIME协议轻松导出表格文件，不用依赖任何组件。按如下格式设置header即可导出Excel，同时浏览器进行下载

<span>header</span>('Content-type: text/html; charset=utf-8'<span>);
</span><span>header</span>("Content-type:application/vnd.ms-excel;charset=UTF-8"); <span>//</span><span>application/vnd.ms-excel指定输出Excel格式</span>
<span>header</span>("Content-Disposition:filename=表格文件名.xls"); <span>//</span><span>输出的表格名称</span>

完整代码如下：

<?<span>php 
</span><span>header</span>('Content-type: text/html; charset=utf-8'<span>);
</span><span>header</span>("Content-type:application/vnd.ms-excel;charset=UTF-8"<span>); 
</span><span>header</span>("Content-Disposition:filename=表格文件名.xls"<span>);
</span><span>$conn</span> = <span>mysql_connect</span>("localhost","root","数据库密码") or <span>die</span>("不能连接数据库"<span>);
</span><span>mysql_select_db</span>("数据库名", <span>$conn</span><span>);
</span><span>mysql_query</span>("set names 'UTF-8'"<span>);
</span><span>$sql</span>="select * from 表名 where 条件"<span>;

</span><span>$result</span>=<span>mysql_query</span>(<span>$sql</span><span>);
</span><span>echo</span> "表头1\t表头2\t表头3\n"<span>;
</span><span>while</span>(<span>$row</span>=<span>mysql_fetch_array</span>(<span>$result</span><span>)){
    </span><span>echo</span> <span>$row</span>[0]."\t".<span>$row</span>[1]."\t".<span>$row</span>[2]."\n"<span>;
}
</span>?>

这里其实\t就是换格，\n就是换行。在一个网页中设置这个php文件的链接，当点击时浏览器会自动把传过来的流保存为Excel文件。
