Question

我正在尝试将关联数组/对象导出到CSV文件。下面是我正在使用的代码示例：

function array_keys_multi(array $array) {
    $uniquekeys = array();
    foreach ($array as $splitArray) {
        $keys = array_keys($splitArray);
        $uniquekeys = array_merge($keys, $uniquekeys);
    }
    return array_unique($uniquekeys);
}

function outputCsv($fileName, $Array)
{
    ob_clean();
    header('Pragma: public');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Cache-Control: private', false);
    header('Content-Type: text/csv');
    header('Content-Disposition: attachment;filename=' . $fileName);    
    if(isset($Array)){
        $fp = fopen('php://output', 'w');
        $keys = array_keys_multi($Array);
        fputcsv($fp, $keys);
        $keys = array_flip($keys);
        foreach($Array AS $values){
            fputcsv($fp, array_merge($keys,$values));
        }
        fclose($fp);
    }
    ob_flush();
}

$data = array(
    array('item' => 'Server', 'cost' => 10000, 'approved_by' => 'Joe'),
    array('item' => 'Mt Dew', 'cost' => 1.25, 'approved_by' => 'John'),
    array('item' => 'IntelliJ', 'cost' => 500, 'approved_by' => 'James', 'extra' => 'data1', 'extra1' => 'data2', 'extra3' => ''),
    array('item' => 'IDEA', 'cost' => 500, 'approved_by' => 'James', 'extra1' => 'data2', 'extra3' => 'data3')
);

outputCsv('expenses.csv', $data);

输出

item     cost   approved_by extra1  extra3  extra
Server   10000  Joe         3       4       8
Mt Dew   1.25   John        3       4       8
IntelliJ 500    James      data2            data1
IDEA     500    James      data2    data3   8

所需的输出

item     cost  approved_by extra extra1 extra3
Server   10000 Joe         null  null   null
MtDew    1.25  John        null  null   null
IntelliJ 500   James       data1 data2  null
IDEA     500   James       data2 null   data3

任何人都可以验证此代码，并让我知道错误在哪里或需要更改吗？

一种简单的方法

if pygame.mixer.Channel(0).get_busy() == True:
    print("playing a sound")
else:
    print("not playing")
