为什么TCPDF结果不显示我是否有数据?

我开发了一个带PHP的软件并使用TCPDF进行报告。它运行良好,但在MySQL中导入大量数据后,PHP无法在浏览器超时之前生成报告。我尝试过最新的firefox和Chrome版本。

这是我的剧本:

     <?php

    require_once('tcpdf/config/lang/eng.php');
    require_once('tcpdf/tcpdf.php');

    // create new PDF documentation
     include "koneksi.php"; //file conection

     $bln=$_POST[BLN];  //for catch month
     $thn=$_POST[THN];  //for catch year
     $exp=$_POST[EXP];  //for catch expedition name


     if(empty($exp))
     {    
       $sql = "SELECT * FROM tb_exp_local where  bulan = '$bln'  AND tahun = '$thn'";
     }
     elseif($exp != "")
     {
       $sql = "SELECT * FROM tb_exp_local where  bulan = '$bln'  AND tahun = '$thn' AND nama_exp = '$exp'";
     }  
       $hasil = mysql_query($sql);


       $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

       // set font
       $pdf->SetFont('times', '', 11);



    // landscape
       $pdf->addPage( 'L', 'LETTER' );

  //this for convert html to pdf with html function    

       $html = '
    <table border="1" cellspacing="3" cellpadding="4">
        <tr><td colspan="9" align="center"><h2>Form Pantauan Expedisi Export</h2></td></tr>
        <tr>
            <th align="center"><b>Tanggal</b></th>
            <th align="center"><b>Nama Expedisi</b></th>
            <th align="center"><b>Nama Distributor</b></th>
            <th align="center"><b>Kota Tujuan</b></th>
            <th align="center"><b>No Faktur</b></th>
            <th align="center"><b>Kondisi Armada Pengiriman</b></th>
            <th align="center"><b>Ketepatan Jumlah</b></th>
            <th align="center"><b>Ketepatan Waktu Kirim</b></th>
            <th align="center"><b>Keterangan</b></th>
        </tr></table>';

       while ($data = mysql_fetch_array($hasil))
       {

         $html .= '<table border="1"><tr><td align="center">'.$data['tgl'].'</td>
                       <td align="center">'.$data['nama_exp'].'</td>
                       <td align="center">'.$data['nama_dist'].'</td>
                       <td align="center">'.$data['kota_tujuan'].'</td>
                       <td align="center">'.$data['faktur'].'</td>
                       <td align="center">'.$data['konarmada'].'</td>
                       <td align="center">'.$data['tepatjml'].'</td>
                       <td align="center">'.$data['tepatwaktu'].'</td> 
                       <td align="center">'.$data['ket'].'</td>  
                       </tr></table> ';

       }

       $pdf->writeHTML($html, true, false, true, false, ''); //for generate




       $pdf->Output('FormPantauExpLocalAll', 'I'); // for generate pdf file

    ?>

服务器超时不依赖于浏览器。尝试在循环中使用set_time_limit(60)

   while ($data = mysql_fetch_array($hasil))
   {
       set_time_limit(60);
       $html .= '(...)';
   }

另外,尝试将INDEX添加到(bulan,tahun,nama_exp)列上的数据库中,它应该加快检索过程。另外,请注意在此过程中可能会耗尽内存(检查服务器上的PHP日志)
