PHP – 另存为文件（excel）
我有一个Excel的工作下载文件，但首先我想把一个下载窗口popup。现在，它会自动生成而不保存文件窗口。 我怎样才能做到这一点。 请帮帮我。
<html> <head> <script language="javascript"> function download() { window.location='report.xls'; } </script> </head> <body alink="#00FF66" link="#00CC00"> <h1 align="center"><a href="javascript:void(0);" onClick="download();">Download Excel Report</a></h1> <?php require_once("db.php"); require_once("excelwriter.class.php"); $excel=new ExcelWriter("report.xls"); if($excel==false) echo $excel->error; $myArr=array("Model","Code","Desc","Stock Requested","Stock Received", "Diff", "On hand"); $excel->writeLine($myArr); $sql="SELECT allinvty3.*, barcode.* , sample.*, count(barcode.itemcode) as icount from barcode INNER JOIN sample on barcode.itemcode = sample.in_code INNER JOIN allinvty3 on barcode.itemcode = allinvty3.in_code group by barcode.itemcode"; $result = $conn->query($sql); if($sql!=false) { $i=1; while($row = $result->fetch_assoc()) { $myArr=array($row['ecr_desc'],$row['itemcode'], $row['ite_desc'],$row['tqty'],$row['icount'], $row['icount'], $row['icount']); $excel->writeLine($myArr); $i++; } } ?> </body> </html> excelwriter.class.php
