php - 创建一个数组数组以提供 CSV 函数

Question

我正在尝试根据查询创建 CSV，我需要符合以下格式的数据:

header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");

$array = array(
    array("data11", "data12", "data13"),
    array("data21", "data22", "data23"),
    array("data31", "data32", "data23"));
outputCSV($array);

我习惯于像这样聚合数据:

while ($row = mysql_fetch_array($result)){
    $values[]   = $row['value'];
}

如何传递 outputCSV 适当的数组？

Answer 1

function outputCSV($rows, $fieldNames = array())
{
    if ($fp = fopen('php://output', 'w')) {
        if ($fieldNames) {
            fputcsv($fp, $fieldNames);
        }
        foreach ($rows as $row) {
            fputcsv($fp, $row);
        }
        fclose($fp);
    }
}
