过去三天，我正在努力使用这个excel文件报告生成。我可以下载该文件。但我想在今天的日期下载该文件。像abcd_14 / 4 / 2014.xls。下面给出了我的代码。请帮我解决这个问题。
excel_report.php
<?php
include("connection.php");
require_once("excel.class.php");
if(isset($_POST['submit']) && $_POST['submit']=="Download")
{
$payor_code = $_POST['payor_code'];
$corp_code= $_POST['corp_code'];
$pro_type = isset($_POST['product_type']);
$submit_date = $_POST['sub_date'];
$dat = date("d/m/Y");
$filename = "Report_$dat";
$excel=new ExcelWriter("reports\STMB_report.xls");
$header = array(
"ReceivedDate",
"SubmissionDate",
"PatientName",
"PatientIC",
"PrincipalName",
"PrincipalIC",
"ClaimNo"
);
//$excel->writeLine($header);
$excel->writeLine($header);
$sql= oci_parse($conn, " select * from members ");
oci_execute($sql);
$dat = date("d/m/Y");
if($sql!=false)
{
while($row=oci_fetch_array($sql))
{
$rec_date = $row['RECEIVED_DATE'];
$sub_date = $row['SUBMISSION_DATE'];
$pat_name = $row['PATIENT_NAME'];
$nric_id = $row['NRIC_ID'];
$pric_name = $row['PRINCIPAL_NAME'];
$pric_nric = $row['PRINCIPAL_NRIC'];
$claim_id = $row['CLAIMS_ID'];
$header=array($rec_date,$sub_date,$pat_name, $nric_id, $pric_name, $pric_nric,$claim_id);
$excel->writeLine($header);
}
}echo "File Download succesfully";
}
?>
Excel类文件是，
excel.class.php
<?php
$dat = date("d/m/Y");
//echo $dat;
$filename = "Report_$dat";
/*

function open($file)

答案 0 :(得分：0)
我认为这应该有用
$ dat = date（＆＃34; d / m / Y＆＃34;）;
$文件名=＆＃34;报告_（＆＃34; $ DAT＆＃34;）。XLS＆＃34 ;;
$ excel = new ExcelWriter（$ filename）;
答案 1 :(得分：0)
你的第一个问题是：
您没有将$ filename传递给Excel类Open方法，以便使用自定义字符串保存文件，即：Report_14 / 4 / 2014.xls
这样做：
$ filename =“Report_ $ dat.xls”;
$ excel = new ExcelWriter（$ filename）;
其次：您无法使用包含无效字符的名称（例如“/”）保存文件，因此更改您调用php date（）函数的拆分字符。
$ dat = date（'d-m-y'）;
此外，关于将内容写入文件：
在尝试使用$ conn连接到数据库之前，您永远不会设置$ conn。如果在connection.php文件中完成此操作，则需要确保可以在调用它的代码范围内访问该变量。
然后我会更改行读数
如果（$ SQL！=假）
到
oci_execute（$ SQL）;
并删除之前对oci_execute（$ sql）;
的调用确保您有数据循环
最后，如果您没有关闭文件阅读器，则不会在文件中看到任何内容。
这是因为许多文件处理程序创建了文件，但是从不在每次“writeLine”调用中写入文件，因为这将需要许多昂贵的硬件IO调用。
因此它将所有这些行写入缓存，并且一旦关闭文件处理程序，它就会将内容写入文件＆gt;
因此，您需要致电
$ excel-＆GT;关闭（）;
你回音的地方
echo“文件下载成功”;
确保将数据保存到文件中。
答案 2 :(得分：0)
你可以试试这个
$ filename =“Report _”。$ dat。“。xls”;
$ excel = new ExcelWriter（$ filename）;
