    function webform_email_menu() {
        $items = array();
         $items['webform_email'] = array(
            'title'             =>  'Webform Email',  //page title
            'description'       =>  'Webform Information',  //description show when mouse hover on link
            'page callback'     =>  'webform_list',  //callback function which is invoked when menu item is called.
            'access callback'   =>  true,  //any user can access this page
           );
         return $items;
    }



function webform_list() {
    module_load_include('inc', 'webform', 'includes/webform.export');
    module_load_include('inc', 'webform', 'includes/webform.components');
    module_load_include('inc', 'webform', 'includes/webform.submissions');  
    $submissions = webform_get_submissions(125);

   $surveycomponents = db_select('webform_component')
     ->fields('webform_component')
     ->condition('nid', 125)
     ->orderBy('weight')
     ->orderBy('name')
     ->execute()
     ->fetchAllAssoc('cid', PDO::FETCH_ASSOC);
$count =0;
$i=2;
   foreach ($submissions as &$submission) {
       $submission_value=$submission->data;
       $i=0;
       foreach($submission_value as $submissionvalue){
            $numItems = count($submission_value);
            if(++$i === $numItems) {
                echo $csv_export="\n";
            }else{
                echo $csv_export=$submissionvalue[0].',';
            }
       }
    }

        $file_open = fopen('sites/default/files/csv/csvfile.csv', "a");
        file_put_contents("sites/default/files/csv/csvfile.csv", $csv_export);
    $csv_handler = fopen ('sites/default/files/csv/csvfile.csv','w');
    fwrite ($csv_handler,$csv_export);
    fclose ($csv_handler);

}

我做错的地方

【解决方案1】：

您可以使用这样的数组将数据存储在 CSV 文件中

$data = [[1,2,3][11,22,33]];
$fp = fopen('test.csv', 'w');

foreach ($data as $fields) {
    fputcsv($fp, $fields);
}
fclose($fp);

【解决方案2】：

检查您的文件夹权限。即站点/默认/文件/csv。它应该是可写的，以便将某些内容写入文件。

【解决方案3】：

我不确定你是否期望，但你需要使用 drupal 函数来获得正确的使用路径并准备对其进行修改：

$path = drupal_realpath('public://').DIRECTORY_SEPARATOR.'csv';
file_prepare_directory($path);
$file_open = fopen($path.'/csvfile.csv', "a");
file_put_contents($path.'/csvfile.csv', $csv_export);
