我正在尝试从 MySQL DB 中的表生成 XLS 文件，但是当 Excel 文件生成“您尝试打开的文件与指定的格式不同”时，Excel 文件格式不正确并给出错误。打开文件时，数据格式不正确。

有什么我想念的想法吗？

<?php
$host = 'XXXXXXX';
$dbname = 'XXXXXXXX';
$username = 'XXXXXXXX';
$password = 'XXXXXXXX';

function xlsBOF() {
    echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0);
    return;
}

function xlsEOF() {
    echo pack("ss", 0x0A, 0x00);
    return;
}

function xlsWriteLabel($Row, $Col, $Value ) {
    $L = strlen($Value);
    echo pack("ssssss", 0x204, 8 + $L, $Row, $Col, 0x0, $L);
    echo $Value;
    return;
}

function xlsWriteNumber($Row, $Col, $Value) {
    echo pack("sssss", 0x203, 14, $Row, $Col, 0x0);
    echo pack("d", $Value);
    return;
}

try {
    $conn = new PDO("mysql:host=$host;dbname=$dbname", $username, $password);
    echo "Connected to $dbname at $host successfully.";
    $conn = null;
} catch (PDOException $pe) {
    die("Could not connect to the database $dbname :" . $pe->getMessage());
}

$q = "SELECT * FROM tablename";
$qr = mysql_query( $q ) or die( mysql_error() );

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");

header("Content-Disposition: attachment;filename=export_".$dbtable.".xls ");

header("Content-Transfer-Encoding: binary ");

xlsBOF();

$col = 0;
$row = 0;

$first = true;

while( $qrow = mysql_fetch_assoc( $qr ) )
{
    if( $first )
    {
      foreach( $qrow as $k => $v )
      {
        xlsWriteLabel( $row, $col, strtoupper( ereg_replace( "_" , " " , $k ) ) );
        $col++;
      }

      $col = 0;
      $row++;
      $first = false;
    }

    // go through the data
    foreach( $qrow as $k => $v )
    {
      // write it out
      xlsWriteLabel( $row, $col, $v );
      $col++;
    }
    // reset col and goto next row
    $col = 0;
    $row++;
}

xlsEOF();
exit();

我不确定 .xls 但为了将 MySQL 结果输出为 CSV 表，fputcsv 函数可以毫不费力地做到这一点：

// Clear any previous output
ob_end_clean();
// I assume you already have your $result
$num_fields = mysql_num_fields($result);

// Fetch MySQL result headers
$headers = array();
$headers[] = "[Row]";
for ($i = 0; $i < $num_fields; $i++) {
    $headers[] = strtoupper(mysql_field_name($result , $i));
}

// Filename with current date
$current_date = date("y/m/d");
$filename = "MyFileName" . $current_date . ".csv";

// Open php output stream and write headers
$fp = fopen('php://output', 'w');
if ($fp && $result) {
    header('Content-Type: text/csv');
    header('Content-Disposition: attachment; filename='.$filename);
    header('Pragma: no-cache');
    header('Expires: 0');
    echo "Title of Your CSV File\n\n";
    // Write mysql headers to csv
    fputcsv($fp, $headers);
    $row_tally = 0;
    // Write mysql rows to csv
    while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
    $row_tally = $row_tally + 1;
    echo $row_tally.",";
        fputcsv($fp, array_values($row));
    }
    die;
}

使用 http://phpexcel.codeplex.com/

C'est la meilleur solution pour générer un fichier excel Vous pouvez même créer plusieurs feuilles dans le fichier et formater les cellules（couleur、police、bordure...）

谷歌翻译：

这是生成 excel 文件的最佳解决方案您甚至可以在文件中创建多个工作表并格式化单元格（颜色、字体、边框......）

这是简单的 Excel 文件生成功能，非常快速且准确的 .xls 文件。

$filename = "sample_php_excel.xls";
$data = array(
array("User Name" => "Abid Ali", "Q1" => "$32055", "Q2" => "$31067", "Q3" => 32045, "Q4" => 39043),
array("User Name" => "Sajid Ali", "Q1" => "$25080", "Q2" => "$20677", "Q3" => 32025, "Q4" => 34010),
array("User Name" => "Wajid Ali", "Q1" => "$93067", "Q2" => "$98075", "Q3" => 95404, "Q4" => 102055),
);
to_xls($data, $filename);

function to_xls($data, $filename){
$fp = fopen($filename, "w+");
$str = pack(str_repeat("s", 6), 0x809, 0x8, 0x0, 0x10, 0x0, 0x0); // s | v
fwrite($fp, $str);
if (is_array($data) && !empty($data)){
    $row = 0;
    foreach (array_values($data) as $_data){
        if (is_array($_data) && !empty($_data)){
            if ($row == 0){
                foreach (array_keys($_data) as $col => $val){
                    _xlsWriteCell($row, $col, $val, $fp);
                }
                $row++;
            }
            foreach (array_values($_data) as $col => $val){
                _xlsWriteCell($row, $col, $val, $fp);
            }
            $row++;
        }
    }
}
$str = pack(str_repeat("s", 2), 0x0A, 0x00);
fwrite($fp, $str);
fclose($fp);
}

function _xlsWriteCell($row, $col, $val, $fp){
if (is_float($val) || is_int($val)){
    $str  = pack(str_repeat("s", 5), 0x203, 14, $row, $col, 0x0);
    $str .= pack("d", $val);
} else {
    $l    = strlen($val);
    $str  = pack(str_repeat("s", 6), 0x204, 8 + $l, $row, $col, 0x0, $l);
    $str .= $val;
}
fwrite($fp, $str);
}
