如何從數組中創建可下載的csv文件？

Question

我有一個這樣的數組：

 $data = [ 
    ["firstname" => "Mary", "lastname" => "Johnson", "age" => 25], 
    ["firstname" => "Amanda", "lastname" => "Miller", "age" => 18], 
    ["firstname" => "James", "lastname" => "Brown", "age" => 31], 
    ["firstname" => "Patricia", "lastname" => "Williams", "age" => 7], 
    ["firstname" => "Michael", "lastname" => "Davis", "age" => 43], 
    ["firstname" => "Sarah", "lastname" => "Miller", "age" => 24], 
    ["firstname" => "Patrick", "lastname" => "Miller", "age" => 27] 
]; 

我想創建此數組在PHP中下載的CSV文件。 這樣的：

Unicode的UTF-8也很重要。

我已經找到了解決辦法：

<?PHP 

function cleanData(&$str) 
{ 
if($str == 't') $str = 'TRUE'; 
if($str == 'f') $str = 'FALSE'; 
if(preg_match("/^0/", $str) || preg_match("/^\+?\d{8,}$/", $str) ||   preg_match("/^\d{4}.\d{1,2}.\d{1,2}/", $str)) { 
    $str = "'$str"; 
    } 
    if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"'; 
    $str = mb_convert_encoding($str, 'UTF-16LE', 'UTF-8'); 

}

// filename for download 
$filename = "website_data_" . date('Ymd') . ".csv"; 

header("Content-Disposition: attachment; filename=\"$filename\""); 
header("Content-Type: text/csv; charset=UTF-16LE"); 

$out = fopen("php://output", 'w'); 

$flag = false; 
foreach ($data as $row) { 
    if(!$flag) { 
    // display field/column names as first row 
    fputcsv($out, array_keys($row), ',', '"'); 
    $flag = true; 
    } 
    array_walk($row, __NAMESPACE__ . '\cleanData'); 
    fputcsv($out, array_values($row), ',', '"'); 
} 

fclose($out); 
exit; 
?> 

它的工作原理，並創建.csv文件，但它顯示出波斯個字符不可讀。

使用http://php.net/manual/en/function.fputcsv.php

$fp = fopen('php://output', 'w'); 
fputcsv($fp, array_keys($data[0])); 

foreach ($data as $row) { 
    fputcsv($fp, array_values($row)); 
} 

fclose($fp); 

轉換陣列UTF8可以使用類似

$dataUTF8 = array_map("utf8_encode", $data);
