将数据导出到Excel，显示下载PHP的数据

Question

我有代码

<?php
    $developersData= array( 
        array("NAME" => "John Doe", "EMAIL" => "[email protected]", "GENDER" => "Male", "COUNTRY" => "United States"), 
        array("NAME" => "Gary Riley", "EMAIL" => "[email protected]", "GENDER" => "Male", "COUNTRY" => "United Kingdom"), 
        array("NAME" => "Edward Siu", "EMAIL" => "[email protected]", "GENDER" => "Male", "COUNTRY" => "Switzerland"), 
        array("NAME" => "Betty Simons", "EMAIL" => "[email protected]", "GENDER" => "Female", "COUNTRY" => "Australia"), 
        array("NAME" => "Frances Lieberman", "EMAIL" => "[email protected]", "GENDER" => "Female", "COUNTRY" => "United Kingdom") 
    );
    $fileName = "export_".date('Ymd') . ".xls";
    header("Content-Type: application/vnd.ms-excel");
    header("Content-Disposition: attachment; filename=\"$fileName\"");  
    $showColoumn = false;
    if(!empty($developersData)) {
      foreach($developersData as $developerInfo) {
        if(!$showColoumn) {      
          echo implode("\t", array_keys($developerInfo)) . "\n";
          $showColoumn = true;
        }
        echo implode("\t", array_values($developerInfo)) . "\n";
      }
    }
    ?>

工作正常之前的代码，但是现在它不使用浏览器

，仅显示数据未下载的数据，
