如何使用php生成.xlsx

Question

我需要生成一个扩展名.xlsx的Excel文件。

以下是我的简单代码：

 $file = "test.xlsx";
 header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
 header('Content-Disposition: attachment; filename='.$file);
 $content = "Col1\tCol2\tCol3\t\n";
 $content .= "test1\ttest1\ttest3\t\n";
 $content .= "testtest1\ttesttest2\ttesttest3\t\n";
 echo $content;

但是当我打开生成的文件时，我会得到这个错误：

Excel cannot open the file 'test.xlsx' because the file format or file extension is not valid.

有什么想法吗？

SimpleXLSXGen

$books = [
    ['ISBN', 'title', 'author', 'publisher', 'ctry' ],
    [618260307, 'The Hobbit', 'J. R. R. Tolkien', 'Houghton Mifflin', 'USA'],
    [908606664, 'Slinky Malinki', 'Lynley Dodd', 'Mallinson Rendel', 'NZ']
];
$xlsx = Shuchkin\SimpleXLSXGen::fromArray( $books );
$xlsx->saveAs('books.xlsx');
//  $xlsx->downloadAs('books.xlsx');

正如其他人所提到的，PhpSpreadsheet为此提供了一个很好的库。假设您拥有通过作曲家安装，并且项目中包含了通过作曲家安装，您可以使用下面的函数从数组中生成xlsx。我在这里包含了大量的评论，以帮助初学者了解PhpSpreadsheet是如何工作的，以及代码正在做什么：

function writeXLSX($filename, $rows, $keys = [], $formats = []) {
    // instantiate the class
    $doc = new \PhpOffice\PhpSpreadsheet\Spreadsheet();
    $sheet = $doc->getActiveSheet();

    // $keys are for the header row.  If they are supplied we start writing at row 2
    if ($keys) {
        $offset = 2;
    } else {
        $offset = 1;
    }

    // write the rows
    $i = 0;
    foreach($rows as $row) {
        $doc->getActiveSheet()->fromArray($row, null, 'A' . ($i++ + $offset));
    }

    // write the header row from the $keys
    if ($keys) {
        $doc->setActiveSheetIndex(0);
        $doc->getActiveSheet()->fromArray($keys, null, 'A1');
    }

    // get last row and column for formatting
    $last_column = $doc->getActiveSheet()->getHighestColumn();
    $last_row = $doc->getActiveSheet()->getHighestRow();

    // autosize all columns to content width
    for ($i = 'A'; $i <= $last_column; $i++) {
        $doc->getActiveSheet()->getColumnDimension($i)->setAutoSize(TRUE);
    }

    // if $keys, freeze the header row and make it bold
    if ($keys) {
        $doc->getActiveSheet()->freezePane('A2');
        $doc->getActiveSheet()->getStyle('A1:' . $last_column . '1')->getFont()->setBold(true);
    }
    
    // format all columns as text
    $doc->getActiveSheet()->getStyle('A2:' . $last_column . $last_row)->getNumberFormat()->setFormatCode(\PhpOffice\PhpSpreadsheet\Style\NumberFormat::FORMAT_TEXT);
    if ($formats) {
        // if there are user supplied formats, set each column format accordingly
        // $formats should be an array with column letter as key and one of the PhpOffice constants as value
        // https://phpoffice.github.io/PhpSpreadsheet/1.2.1/PhpOffice/PhpSpreadsheet/Style/NumberFormat.html
        // EXAMPLE:
        // ['C' => \PhpOffice\PhpSpreadsheet\Style\NumberFormat::FORMAT_NUMBER_00, 'D' => \PhpOffice\PhpSpreadsheet\Style\NumberFormat::FORMAT_NUMBER_00]
        foreach ($formats as $col => $format) {
            $doc->getActiveSheet()->getStyle($col . $offset . ':' . $col . $last_row)->getNumberFormat()->setFormatCode($format);
        }
    }

    // write and save the file
    $writer = new PhpOffice\PhpSpreadsheet\Writer\Xlsx($doc);
    $writer->save($filename);
}

示例用法：

$rows = [
    ['sku' => 'A123', 'price' => '99'],
    ['sku' => 'B456', 'price' => '5.35'],
    ['sku' => 'C789', 'price' => '17.7']
];
$keys = array_keys(current($rows));
$formats = ['B' => \PhpOffice\PhpSpreadsheet\Style\NumberFormat::FORMAT_NUMBER_00];

writeXLSX('pricelist.xlsx', $rows, $keys, $formats);

如果使用的是旧版本的PHPSpreadsheet，仍然可以使用以前的版本。

在项目目录中安装PHPSpreadsheet时，必须包括它的版本号。

这对我起了作用：
