附加括號文件

Question

在開始和我有追加括號我的CSV文件看起來像內容的結局這

 date1,success,failure,count 
     1427653800,95,65,160 
     1427653800,30,10,40 
     1427740200,10,8,18 
     1427740200,30,38,68 
     1427826600,38,20,58 
     1427826600,60,10,70 
     1427653800,15,15,30 
     1427653800,10,10,20 

加括號的內容應該是這樣的後： [1427653800,95,65,160] 我的PHP代碼如下：

<?php 
     $list = array ('date1', 'success', 'failure','count'); 

     $sql = "SELECT (SUBSTRING(UNIX_TIMESTAMP(date1),1,10)),success,failure,count from h_statistics;"; 
       $users_profile_user_id = mysqli_query($conn, $sql); 

      $fp = fopen("data.csv", "w"); 

      fputcsv($fp, $list); 
     while($row = mysqli_fetch_array($users_profile_user_id, MYSQLI_ASSOC)) 
     { 

      fputcsv($fp, $row); 

     } 

     fclose($fp); 
    ?> 

this is my conn.php file ,please suggest me on this 

Answer 1

最好是使用此查詢

$sql = "SELECT CONCAT('[','',(SUBSTRING(UNIX_TIMESTAMP(date1),1,10))),success,failure,CONCAT(count,'',']') from h_statistics"; 

它給你造成像[1427653800,95,65,160]所以沒有必要做任何的代碼在你while循環

Answer 2

嘗試追加和前面加上括號：

$row[0] = '['.$row[0]; 
$row[3] .= ']'; 
fputcsv($fp, $row); 

Answer 3

嘗試用我的功能被添加文本到關聯數組的第一個和最後一個元素：

<?php 

function array_brackets($array,$prefix,$suffix){ 

//add prefix to the first element 
end($array); 
$key = key($array); 
$array[$key] = $prefix . $array[$key]; 

//add sufix to the last element 
reset($array); 
$key = key($array); 
$array[$key] = $array[$key] . $suffix; 

return $array; 
} 


$list = array ('date1', 'success', 'failure','count'); 

$sql = "SELECT (SUBSTRING(UNIX_TIMESTAMP(date1),1,10)),success,failure,count from h_statistics;"; 
     $users_profile_user_id = mysqli_query($conn, $sql); 

    $fp = fopen("data.csv", "w"); 

    fputcsv($fp, $list); 
while($row = mysqli_fetch_array($users_profile_user_id, MYSQLI_ASSOC)) 
{ 

    fputcsv($fp, array_brackets($row,"[","]")); 

} 

fclose($fp); 

?> 

Answer 4

請運行該代碼，並給我的輸出：

<?php 

$list = array ('date1', 'success', 'failure','count'); 

$sql = "SELECT (SUBSTRING(UNIX_TIMESTAMP(date1),1,10)),success,failure,count from h_statistics;"; 
     $users_profile_user_id = mysqli_query($conn, $sql); 

    //$fp = fopen("data.csv", "w"); 

    //fputcsv($fp, $list); 
while($row = mysqli_fetch_array($users_profile_user_id, MYSQLI_ASSOC)) 
{ 

    //fputcsv($fp, array_brackets($row,"[","]")); 
    print_r($row); 
    exit; 
} 

//fclose($fp); 

?>
