Question

我使用下面非常简单的代码导出我所有MySQL表格数据的CSV，＆＃34;成员＆＃34;。但是，MySQL表中总共有560行，但CSV只显示了MySQL表的559行（它没有显示第一个数据库的表行）。有谁知道为什么会这样，或者为了解决这个问题，我可以在代码中修改一下？

// BEGIN EXPORT ALL FROM EDITOR
if(isset($_POST['export_csv'])) {
    $today_date = date('Y-m-d_h-i-s-a', time());
    $FileName = "download/report_mailing_list_export_".$today_date.".csv";
    $file = fopen($FileName,"w");

        $sql = mysqli_query($dbc, "SELECT * FROM member WHERE memberid != 1 AND deleted=0 AND website = 0 ORDER BY last_name, first_name DESC");

        $row = mysqli_fetch_assoc($sql);
    // Save headings alon
        $HeadingsArray=array();
        foreach($row as $name => $value){
            $HeadingsArray[]=$name;
        }

        fputcsv($file,$HeadingsArray);

    // Save all records without headings
        while($row = mysqli_fetch_assoc($sql)){
        $valuesArray=array();
            foreach($row as $name => $value){
            $valuesArray[]=$value;
            }
        fputcsv($file,$valuesArray);
        }
        fclose($file);

    header("Location: $FileName");
}
// END EXPORT

你调用mysqli_fetch_assoc（$ sql）;在while循环之前，迭代第一行。您可以将其更改为以下内容：

// BEGIN EXPORT ALL FROM EDITOR
if(isset($_POST['export_csv'])) {
    $today_date = date('Y-m-d_h-i-s-a', time());
    $FileName = "download/report_mailing_list_export_".$today_date.".csv";
    $file = fopen($FileName,"w");

        $sql = mysqli_query($dbc, "SELECT * FROM member WHERE memberid != 1 AND deleted=0 AND website = 0 ORDER BY last_name, first_name DESC");

        $row = mysqli_fetch_assoc($sql);
    // Save headings alon
        $HeadingsArray=array();
        foreach($row as $name => $value){
            $HeadingsArray[]=$name;
        }

        fputcsv($file,$HeadingsArray);

    // Save all records without headings
        do {
            $valuesArray=array();
            foreach($row as $name => $value){
                $valuesArray[]=$value;
            }
            fputcsv($file,$valuesArray);
        } while($row = mysqli_fetch_assoc($sql));
        fclose($file);

    header("Location: $FileName");
}
// END EXPORT

在这种情况下，您将从第一次迭代中重用$row。

PHP fputcsv没有从SQL查询输出第一行（在第一行之后输出所有其他行）
