PhP导出.csv将分隔符从逗号更改为其他人

您可以使用fputcsv()以csv格式生成数据

int fputcsv ( resource $handle , array $fields [, string $delimiter = "," [, string $enclosure = '"' [, string $escape_char = "\" ]]] )

编辑:

你的代码看起来像这样:

0) {
    $row = mysqli_fetch_assoc($rs2);

    $delimiter = ';';
    $data = [];
    foreach ($row as $name => $value){
        $data[] = $name;
    }
    fputcsv($fp, $data, $delimiter);


    mysqli_data_seek($rs2,0);

    while ($row = mysqli_fetch_assoc($rs2)){
        fputcsv($fp, $row, $delimiter);
    }

    fclose($fp);

    header('Content-Type: text/csv');
    header("Content-Disposition: attachment; filename=$date.csv");
    header('Pragma: no-cache');

    echo $seperator;
}
else {
    fclose($fp);

    header('Content-Type: text/csv');
    header("Content-Disposition: attachment; filename=$date.csv");
    header('Pragma: no-cache');
    echo "No record modified today";
}
