CSV至Json，标题行为键

只需分别阅读第一行并将其合并到每一行：

if (($handle = fopen('upload/BEN-new.csv', 'r')) === false) {    die('Error opening file');}$headers = fgetcsv($handle, 1024, ',');$complete = array();while ($row = fgetcsv($handle, 1024, ',')) {    $complete[] = array_combine($headers, $row);}fclose($handle);echo json_enpre($complete);
