php - php导出数据库数据，导出excel的文件格式应为windows 97-2003 workbook

Question

下面是我从 mysql 数据库导出数据的代码。它工作正常，但在导出 excel 文件时，文件保存为制表符格式。我只需要将它保存在 Windows 97-2003 工作簿中。我一直在更改标题，但它不起作用.. 当打开这些文件时，它会弹出一些警告，例如“您尝试打开的文件，'filename.xls'，其格式与文件扩展名指定的格式不同。 ” 我需要摆脱它。任何人都可以提出建议..提前致谢:)

HTML编码:

<input type="submit" name="frmDownload" id="frmDownload" value="CSV" title="Export" class="frmDownloadButton" />
<input type="submit" name="frmDownload" id="frmDownload" value="Excel" title="Export" class="frmDownloadButton" />
<input type="submit" name="frmDownload" id="frmDownload" value="TEXT" title="Export" class="frmDownloadButton" />
<input type="submit" name="frmDownload" id="frmDownload" value="XML" title="Export" class="frmDownloadButton" />  

PHP例程:

if ($_POST["frmDownload"]) { 
    $output = "";
    $line_terminated="\r\n";
    $strDatas = array();
    $field_terminated = doGetFieldDelimeter($_POST);
    $export_schema = "Name".$field_terminated."Code".$field_terminated."Email".$field_terminated."Designation".$field_terminated."Number".$field_terminated."Salary".$field_terminated."Age";
    $strDataQuery = doSelectRecords();
    $strDatas = $strDataQuery;
    $output.= doGetExportSchema($_POST,$export_schema);
    $delimeter = doGetDelimeterForTextFile($_POST);
    $output.= doExportData($_POST, $strDatas, $field_terminated, $line_terminated, $delimeter);
    $output.= doGetXmlTitle($_POST);
    doGetHeader($_POST,$output,$objPHPExcel);
    echo $output;
    exit;
}

    return MakeStripSlashes($record);

您可以告诉您的 MySQL 数据库将其转储为 CSV:

$file = 'D:/path/to/website/dump.sql';

// The SELECT...INTO query is unable to overwrite if the
// file already exists, so delete it beforehand:
if (is_file($file))
    unlink($file);

$query = "
    SELECT id, title, created   -- The fields to export
    INTO OUTFILE '{$file}'      -- The file
    FIELDS TERMINATED BY ','    -- Delimiter
    OPTIONALLY ENCLOSED BY '\"' -- Quote if necessary
    LINES TERMINATED BY '\n'    -- End line with LF newline
    FROM tbl_employee           -- Table name
";

$db = new MySQLi('localhost', 'root', '', 'your_database');
$db->query($query);

// Show any errors...
if ($db->error) {
    var_dump($db->error);
}
