Excel的下載卡住188KB

嗨，我在導出Excel格式我的MySQL數據目前我有14K +的記錄，但問題是它卡住@ 188KB但是當我試圖修剪下來的結果，以100只記錄不中斷下載。Excel的下載卡住188KB

這裏是我的代碼：

function xlsBOF() { 
    echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0); 
    return; 
} 

function xlsEOF() { 
    echo pack("ss", 0x0A, 0x00); 
    return; 
} 

function xlsWriteNumber($Row, $Col, $Value) { 
    echo pack("sssss", 0x203, 14, $Row, $Col, 0x0); 
    echo pack("d", $Value); 
    return; 
} 

function xlsWriteLabel($Row, $Col, $Value) { 
    $L = strlen($Value); 
    echo pack("ssssss", 0x204, 8 + $L, $Row, $Col, 0x0, $L); 
    echo $Value; 
return; 
} 

    mysql_connect($dbhost,$dbuser,$dbpass); 
    //mysql_select_db($dbname) or die("Unable to select database"); 
    $result = mysql_db_query($dbname, "select id, or_number, name, client_code, address, vehicle_info, vehicle_color, plate_num, sticker_type, application_date, amount_paid, traffic_violations, delivery_date, edited_by, phase, version FROM owner order by application_date desc");

      xlsBOF(); 
      xlsWriteLabel(0,0,"Current SLVA Owner List:"); 
      xlsWriteLabel(2,0,"#"); 
      xlsWriteLabel(2,1,"OR #"); 
      xlsWriteLabel(2,2,"Name");

      xlsWriteLabel(2,12,"Delivery Date"); 
      xlsWriteLabel(2,13,"Edited By"); 
      xlsWriteLabel(2,14,"Phase"); 
      xlsWriteLabel(2,15,"Version"); 


      $xlsRow = 3; 
      while(list($id, $or_number, $name, $client_code, $address, $vehicle_info, $vehicle_color, $plate_num, $sticker_type, $application_date, $amount_paid, $traffic_violations, $delivery_date, $edited_by, $phase, $version) = mysql_fetch_row($result)) { 
         xlsWriteLabel($xlsRow,0, $id); 
         xlsWriteLabel($xlsRow,1,$or_number); 
         xlsWriteLabel($xlsRow,2,$name); 
         xlsWriteLabel($xlsRow,3,$client_code); 
         xlsWriteLabel($xlsRow,4,$address); 
         xlsWriteLabel($xlsRow,5,$vehicle_info); 
         xlsWriteLabel($xlsRow,6,$vehicle_color); 
         xlsWriteLabel($xlsRow,7,$plate_num); 
         xlsWriteLabel($xlsRow,8,$sticker_type); 
         xlsWriteLabel($xlsRow,9,$application_date); 
         xlsWriteLabel($xlsRow,10,$amount_paid); 
         xlsWriteLabel($xlsRow,11,$traffic_violations);  
         xlsWriteLabel($xlsRow,12,$delivery_date); 
         xlsWriteLabel($xlsRow,13,$edited_by); 
         xlsWriteLabel($xlsRow,14,$phase);  
         xlsWriteLabel($xlsRow,15,$version); 

        $xlsRow++; 
       } 
       xlsEOF(); 
      exit();

我去了幾個網站/線程，但仍然沒有找到解決方案。：'（

請把'的var_dump（$結果）''$後result'已定，地方張貼，或至少聽起來像是一個變音問題，總是會出現問題，例如[PEAR'S Spread [Writer]（http://pear.php.net/package/Spreadsheet_Excel_Writer/redirected）和其他excel庫。 – GodLesZ

這只是胡亂猜測，但你可能需要提前計算的文檔大小，並設置一個‘內容長度’標頭

header("Content-length: " . strlen($document));

您將有你的輸出存儲在字符串，就可以計算出長度（輸出緩衝可能有助於捕捉xlsWriteLabel的使用）

ob_start(); 
xlsBOF(); 
xlsWriteLabel(); 
// etc etc 
xlsEOF(); 
$document = ob_get_contents(); 
ob_end_clean(); 
header("Content-length: " . strlen($document)); 
echo $document; 
exit();
