Array output and adding a character

本文关键字：字符添加输出数组 | 更新日期: 2023-09-27

当用户点击提交时，我希望将帖子数据保存到 cvs 文件中。我想在每个变量后用"，"将 $valid[$var] 输出到$cvsData中......我在哪里做这样的事情？我也在看fputcsv通过输入"，"

    $valid = true; 
    foreach($_POST as $var => $value) { 
        if(empty($value)) { 
            $valid[$var] = false;
        } else {
            $valid[$var] = true;
        }
    }

$cvsData = $phone .'",'" .$fn .'",'" .$ln .'",'" .$sos .'",'" .$e 1 。"'";

header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");
$line = "";
foreach($_POST as $value)
{
    if(!empty($value))
    {
        echo '"" . str_replace('"', ''"', $value) . '", ';
    }
}
$line = trim($line, '", ');
echo $line;

您是否正在寻找这样的东西：

$valid = true;
$csvHeaders=""; 
$csvData="";
foreach($_POST as $var => $value) 
{ 
    if(!empty($value)) 
    {
        $csvHeaders.=$var.",";
        $csvData.=$value.",";
    }
}
echo $csvHeaders;
echo $csvData;
