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$data->sheets[0][行][列]的值,插入操作就好办了。
导出可以利用MIME协议轻松导出表格文件,不用依赖任何组件。按如下格式设置header即可导出Excel,同时浏览器进行下载
<span>header</span>('Content-type: text/html; charset=utf-8'<span>); </span><span>header</span>("Content-type:application/vnd.ms-excel;charset=UTF-8"); <span>//</span><span>application/vnd.ms-excel指定输出Excel格式</span> <span>header</span>("Content-Disposition:filename=表格文件名.xls"); <span>//</span><span>输出的表格名称</span>
完整代码如下:
<?<span>php </span><span>header</span>('Content-type: text/html; charset=utf-8'<span>); </span><span>header</span>("Content-type:application/vnd.ms-excel;charset=UTF-8"<span>); </span><span>header</span>("Content-Disposition:filename=表格文件名.xls"<span>); </span><span>$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。
