將mysql數據導出爲ex​​cel時的錯誤消息

<?php

     { 
      if(!isset($row[$j])) 
       $schema_insert .= "NULL".$sep; 
      elseif ($row[$j] != "") 
       $schema_insert .= "$row[$j]".$sep; 
      else 
       $schema_insert .= "".$sep; 
     } 
     $schema_insert = str_replace($sep."$", "", $schema_insert); 
     $schema_insert = preg_replace("/\r\n|\n\r|\n|\r/", " ", $schema_insert); 
     $schema_insert .= "\t"; 
     print(trim($schema_insert)); 
     print "\n"; 
    } 
?> 

我試圖使用上面的Peter代碼。 數據導出很好，但正在拋出以下錯誤消息：

'database.xls'的文件格式和擴展名不匹配。文件 可能已損壞或不安全。除非你信任它的源碼不要打開 它。你還想打開嗎？

我試過不同的文件擴展名，但無法修復它。

錯誤的原因是您正在創建一個文本文件，其中字段由製表符分隔，而不是Excel文件。

簡單地改變行：

header("Content-Type: application/xls"); 
header("Content-Disposition: attachment; filename=$filename.xls"); 

有：

header("Content-Type: text/plain"); 
header("Content-Disposition: attachment; filename=$filename.txt"); 

，或者：

header("Content-Type: text/csv"); 
header("Content-Disposition: attachment; filename=$filename.csv"); 

然後你也可以打開此文件從Excel。
