Question

我试图将我的数组导出为CSV文件。我已经阅读了this个问题，现在我可以下载CSV了。问题是，CSV文件中还包含整个html文档，我不知道它来自哪里。

数组如下所示：

Array
(
    [0] => Array
        (
            [id] => 1
            [tphInventoryNumber] => D17001
            [title] => Assets in Leasing
            [price] => 1299.95
            [recievedDate] => 2017-11-02
            [departement] => 1
            [unit] => 1
        )

    [1] => Array
        (
            [id] => 2
            [tphInventoryNumber] => D17002
            [title] => Assets in Leasing
            [price] => 12.05
            [recievedDate] => 2017-10-31
            [departement] => 7
            [unit] => 3
        )

)

我导出CSV的功能如下所示：

function exportToCSV($array, $filename = "export.csv", $delimiter = ";"){
  header('Content-Type: application/csv; charset=UTF-8');
  header('Content-Disposition: attachment;filename="'.$filename.'";');
  $f = fopen('php://output', 'w');
  foreach ($array as $line) {
      fputcsv($f, $line, $delimiter);
  }
}

知道我在这里做错了什么吗？我无法找到解决此问题的任何方法......

更新

我通过发送帖子变量的按钮调用该函数。

形式：

<form action="start.php?load=export" method="post">
  <input type="hidden" name="exportCSV" value="exportCSV">
  <button class="btn btn-info" type="submit">CSV Export</button>
</form>

检查后置变量：

if (isset($_POST['exportCSV'])) {
  exportToCSV($arrayCSV);
}

这是CSV的实际内容：

    <head>
      <meta charset="utf-8">

Answer 1

我只能假设您的框架导致控制器操作输出视图或类似内容。您需要在函数末尾添加exit;或die;。例如：

function exportToCSV($array, $filename = "export.csv", $delimiter = ";") {
    header('Content-Type: application/csv; charset=UTF-8');
    header('Content-Disposition: attachment;filename="'.$filename.'";');
    $f = fopen('php://output', 'w');
    foreach ($array as $line) {
        fputcsv($f, $line, $delimiter);
    }

    // halt execution of the script after output stream finalised
    exit;
}

更新：您似乎已将某些html输出写入输出缓冲区，因此您需要先使用ob_end_clean();清除它。见下面的例子：

function exportToCSV($array, $filename = "export.csv", $delimiter = ";") {
    header('Content-Type: application/csv; charset=UTF-8');
    header('Content-Disposition: attachment;filename="'.$filename.'";');

    // clean output buffer
    ob_end_clean();

    $f = fopen('php://output', 'w');
    foreach ($array as $line) {
        fputcsv($f, $line, $delimiter);
    }

    // halt execution of the script after output stream finalised
    exit;
}

Answer 2

将您的函数调用更改为此。

if (isset($_POST['exportCSV'])) {
  exportToCSV($arrayCSV);
  die;
}

将数组导出到csv将整个html文档导出到csv中
