將數組轉換爲csv

Question

如何將數組轉換爲CSV文件？

這是我的數組：

stdClass Object 
(

    [OrderList_RetrieveByContactResult] => stdClass Object 
     (
      [OrderDetails] => stdClass Object 
       (
        [entityId] => 1025298 
        [orderId] => 10952 
        [orderName] => testing 
        [statusTypeId] => 4652 
        [countryCode] => AU 
        [orderType] => 1 
        [invoiceNumber] => 0 
        [invoiceDate] => 0001-01-01T00:00:00 
        [userID_AssignedTo] => 11711 
        [shippingAmount] => 8.95 
        [shippingTaxRate] => 0 
        [shippingAttention] => 
        [shippingInstructions] => 
        [shippingOptionId] => 50161 
        [discountCodeId] => 0 
        [discountRate] => 0 
        [totalOrderAmount] => 408.45 
        [directDebitTypeId] => 0 
        [directDebitDays] => 0 
        [isRecur] => 
        [nextInvoiceDate] => 0001-01-01T00:00:00 
        [endRecurDate] => 0001-01-01T00:00:00 
        [cycleTypeID] => 1 
        [createDate] => 2010-10-08T18:40:00 
        [lastUpdateDate] => 2010-10-08T18:40:00 
        [deleted] => 
        [products] => stdClass Object 
         (
          [Product] => stdClass Object 
           (
            [productId] => 674975 
            [productCode] => 
            [productDescription] => 
            [units] => 10 
            [unitPrice] => 39.95 
            [unitTaxRate] => 0 
            [totalProductPrice] => 399.5 
            [productName] => Acne Clearing Gel 
           ) 

         ) 

        [addresses] => stdClass Object 
         (
          [Address] => stdClass Object 
           (
            [addressTypeID] => 8 
            [addressLine1] => Cebu City 
            [city] => Cebu 
            [zipcode] => 6000 
            [state] => 
            [countryCode] => PH 
           ) 

         ) 

       ) 

     ) 

)

我用下面的函數，該函數;這是對fputscsv評論中男性作品之一的改編。而且你可能想要將這個數組展平。不知道如果你通過多維度會發生什麼。

/** 
    * Formats a line (passed as a fields array) as CSV and returns the CSV as a string. 
    * Adapted from http://us3.php.net/manual/en/function.fputcsv.php#87120 
    */ 
function arrayToCsv(array &$fields, $delimiter = ';', $enclosure = '"', $encloseAll = false, $nullToMysqlNull = false) { 
    $delimiter_esc = preg_quote($delimiter, '/'); 
    $enclosure_esc = preg_quote($enclosure, '/'); 

    $output = array(); 
    foreach ($fields as $field) { 
     if ($field === null && $nullToMysqlNull) { 
      $output[] = 'NULL'; 
      continue; 
     } 

     // Enclose fields containing $delimiter, $enclosure or whitespace 
     if ($encloseAll || preg_match("/(?:${delimiter_esc}|${enclosure_esc}|\s)/", $field)) { 
      $output[] = $enclosure . str_replace($enclosure, $enclosure . $enclosure, $field) . $enclosure; 
     } 
     else { 
      $output[] = $field; 
     } 
    } 

    return implode($delimiter, $output); 
}

function array_2_csv($array) { 
    $csv = array(); 
    foreach ($array as $item) { 
     if (is_array($item)) { 
      $csv[] = array_2_csv($item); 
     } else { 
      $csv[] = $item; 
     } 
    } 
    return implode(',', $csv); 
} 

$csv_data = array_2_csv($array); 

echo "<pre>"; 
print_r($csv_data); 
echo '</pre>' ;

我的解決方案需要陣列以不同的格式比問題提供：

<? 
    $data = array(
     array('row_1_col_1', 'row_1_col_2', 'row_1_col_3'), 
     array('row_2_col_1', 'row_2_col_2', 'row_2_col_3'), 
     array('row_3_col_1', 'row_3_col_2', 'row_3_col_3'), 
    ); 
?> 

我們定義功能：

<? 
    function outputCSV($data) { 
     $outputBuffer = fopen("php://output", 'w'); 
     foreach($data as $val) { 
      fputcsv($outputBuffer, $val); 
     } 
     fclose($outputBuffer); 
    } 
?> 

然後我們輸出我們作爲一個CSV數據：

<? 
    $filename = "example"; 

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

    outputCSV($data); 
?> 

我已經在幾個項目中使用了它，它運行良好。我應該注意到outputCSV的代碼比我更聰明，所以我相信我不是原作者。不幸的是，我已經失去了我所掌握的地方，所以我不能把它歸功於誰。

輕微適應上述的解決由kingjeffrey當你想創建和模板內回聲CSV（即 - 大多數框架將啓用輸出緩衝，你需要設置頁眉等在控制器）

// Create Some data 
<?php 
    $data = array(
     array('row_1_col_1', 'row_1_col_2', 'row_1_col_3'), 
     array('row_2_col_1', 'row_2_col_2', 'row_2_col_3'), 
     array('row_3_col_1', 'row_3_col_2', 'row_3_col_3'), 
    ); 


// Create a stream opening it with read/write mode 
$stream = fopen('data://text/plain,' . "", 'w+'); 

// Iterate over the data, writting each line to the text stream 
foreach ($data as $val) { 
    fputcsv($stream, $val); 
} 

// Rewind the stream 
rewind($stream); 

// You can now echo it's content 
echo stream_get_contents($stream); 

// Close the stream 
fclose($stream); 

感謝上面的Kingjeffrey以及這個blog post，我發現了關於創建文本流的信息。

嗯，也許有點晚了4年後哈哈......但我一直在尋找的解決方案做對象CSV，但是這裏大多數解決方案實際上是一個數組CSV ...

一些修修補補後，在這裏是我的解決方案，將對象轉換爲CSV，我覺得很整齊。希望這會幫助別人。

$resp = array(); 
foreach ($entries as $entry) { 
    $row = array(); 
    foreach ($entry as $key => $value) { 
     array_push($row, $value); 
    } 
    array_push($resp, implode(',', $row)); 
} 
echo implode(PHP_EOL, $resp); 

注意，對於$key => $value工作，你object的屬性必須是公共的，私人的人不會得到牽強。

最終的結果是，你得到的東西是這樣的：

blah,blah,blah 
blah,blah,blah
