PHP的Excel导出没有被Office 2007识别
我已经使用堆栈溢出好几年了，但现在只有一个帐户，因为我从来没有变得如此卡住，我需要问一个问题（不是因为我很聪明，因为我的代码很简单！），无论如何对我的问题
我正在通过PHP以.xls格式导出表格，并使用我的MYSQL表格中的一些表格提供的信息。 所有的信息和造型完美的作品。 唯一的问题是，当它在办公室2007年打开我得到这个错误消息：
“您试图打开的文件'export.xls'是与文件扩展名指定的格式不同的格式。在打开文件之前，确认文件没有被破坏，并且来自可靠来源。查看这个文件？“
所以总结一下，所有的信息都从数据库中取得成功，所有的样式工作 – 我知道这是真实的，因为当我点击popup的对话框中的“是”，我看到一切都完美布局。
以下是Excel导出器类：

这是我的实施与敏感信息审查;
$excel = new excel_xml(); $header_style = array( 'bold' => 1, 'size' => '14', 'color' => '#FFFFFF', 'bgcolor' => '#4F81BD' ); $excel->add_style('header', $header_style); $header_style2 = array( 'bold' => 1, 'color' => '#FFFFFF', 'bgcolor' => '#92d050' ); $excel->add_style('green', $header_style2); $header_style3 = array( 'bold' => 1, 'color' => '#FFFFFF', 'bgcolor' => '#c00000' ); $excel->add_style('error', $header_style3); $header_style4 = array( 'bold' => 1, 'color' => '#FFFFFF', 'bgcolor' => '#e46d0a' ); $excel->add_style('orange', $header_style4); $header_style5 = array( 'bold' => 1, 'color' => '#FFFFFF', 'bgcolor' => '#c00000' ); $excel->add_style('red', $header_style5); /** * Add row and attach the style "header" to it */ $excel->add_row(array( 'col1', 'col2', 'col3', 'col4', 'col5' ), 'header'); /** * Add some rows, if you encapsulate the string inside asterisks, * they will get bold using the predefined style "bold" * If you append "|x" where x is a number, that cell will be * merged with the x following cells */ $excel->add_row(array( $Queried_Info_From_DB1, $Queried_Info_From_DB2, $Queried_Info_From_DB3, $Queried_Info_From_DB4, $Queried_Info_From_DB5 ), 'red'); if(mysql_num_rows($result) == 0){ $excel->add_row(array( 'You have no info to display!|4' ), 'error'); } /** * Tell the object to create the worksheet. * The passed string is the name of the worksheet */ $excel->create_worksheet('Your info'); /** * If you invoke the generate method, you will get the * XML returned or... */ $xml = $excel->generate(); /** * ... you can pass the whole thing for download with * the passed string as the filename */ $excel->download('Export');
您正在编写一个电子表格XML格式的文件，而不是BIFF（.xls）格式，所以MS Excel会在这种差异上抱怨。 尝试使用.xml的文件扩展名保存它（因为这就是您实际创build的）
