[英]PHP output empty ZIP
This script successfully generated the pdfs to a folder tmp/.... 此脚本成功生成pdf到文件夹tmp / ....
However the ZIP output to the browser is empty and I don't know what I have done wrong. 然而,浏览器的ZIP输出是空的,我不知道我做错了什么。
$file = tempnam("tmp", "zip");
$zip = new ZipArchive();
// Zip will open and overwrite the file, rather than try to read it.
$zip->open($file, ZipArchive::OVERWRITE);
foreach( explode( ',', $_POST["ids"]) as $Client_ID)
{
$sql_qry="select *
from ca_client_statement
where client_id='".$Client_ID."' and trading_period_month like '".$TP_Month."'";
$sql_err_no=sql_select($sql_qry,$sql_res,$sql_row_count,$sql_err,$sql_uerr);
//echo $sql_qry;
//echo '<br/>';
$row = mysql_fetch_assoc($sql_res);
$file_content = $row['pdf_statement'];
$file_name = 'tmp/'.$Client_ID.'statement.pdf';
$pdf=file_put_contents($file_name, $file_content);
$zip->addFile($pdf);
}
$zip->close();
// Stream the file to the client
header("Content-Type: application/zip");
header("Content-Length: " . filesize($file));
header("Content-Disposition: attachment; filename=\"a_zip_file.zip\"");
readfile($file);
unlink($file);
file_put_contents()
returns the number of bytes written, not the file name. file_put_contents()
返回写入的字节数,而不是文件名。 Try changing the line right after it to this: 尝试将其后面的行更改为:
$zip->addFile($file_name);
