我有下面的代码，它现在已经运行了一年多了，但今天它给出了最大执行时间错误。我尝试增加php.ini上的数字，但它没有解决。还尝试将max_execution_time直接添加到php代码中，它也没有帮助。任何人都可以帮我弄清楚为什么它现在会破裂？当我尝试从网页上访问它以下载pdf文件时，它会显示＆＃34; https://webpage.address.com/quicklistpdf.php?user= $用户的网页可能暂时关闭，或者它可能已永久移动到新的网址。 ERR_INVALID_RESPONSE
感谢。

答案 0 :(得分：0)
我在您的代码中注意到的一些事情可能会增加加载时间或为您搞砸。对于初学者来说，您可以通过快速循环来减少代码。
此
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(8);
$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(9);
$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(8);
$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(7);
...
$objPHPExcel->getActiveSheet()->getColumnDimension('R')->setWidth(7);
可以更改为
$col = 'A';
$col_width = 7;
for($i=0;$i<=17;$i++) {
if($col === ('A'||'C')) {
$col_width = 8;
} else if($col === 'B') {
$col_width = 9;
}
$objPHPExcel->getActiveSheet()->getColumnDimension($col)->setWidth($col_width);
$col++;
}
其次，如果您要设置$objWorksheet = $objPHPExcel->getActiveSheet();，那么您可以将其放在首位，并将所有$objPHPExcel->getActiveSheet()替换为$objWorksheet。例如，此代码将如下所示：
$col = 'A';
$col_width = 7;
for($i=0;$i<=17;$i++) {
if($col === ('A'||'C')) {
$col_width = 8;
} else if($col === 'B') {
$col_width = 9;
}
$objWorksheet->getColumnDimension($col)->setWidth($col_width);
$col++;
}
最后，为了回答你的问题，你需要清理，然后设置标题，然后使用编写器，最后从工作簿中分离（退出）。好吧，无论如何，这对我来说都是如此。
像这样更新此代码。
//set after doc creation but before setting headers
ob_end_clean();
$filedate=date('dmY');
$filename='QuickList_'.$filedate.'.pdf';
//Redirect output to a client’s web browser (PDF)
header('Content-Type: application/pdf');
//Redirect output to a client’s web browser (Excel2007)
//header('Content-Type: application/xlsx');
header('Content-Disposition: attachment;filename='.$filename);
//header('Cache-Control: max-age=0');
//If you're serving to IE 9, then the following may be needed
header('Cache-Control: max-age=1');
//If you're serving to IE over SSL, then the following may be needed
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header ('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT'); // always modified
header ('Cache-Control: cache, must-revalidate'); // HTTP/1.1
header ('Pragma: public'); // HTTP/1.0
//Save Excel 2007 file
//$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'PDF')->save('php://output');
//dont forget to exit
exit;//to detach from objWriter properly
如果这不能解决问题，那么我会查看你的quicklistQueries.php，看看你的查询是否是导致过度使用执行时间的原因。它可能需要在结果迭代之前或之间进行flush（）或垃圾回收。
$result=pg_query($sql_data);
//flush database and clear memory then go through results
