[PHP] file downloads using header problem
I am trying to force a file download using headers. The problem is not forcing the download. That is working fine, but if the user wants to click on another download while the first one is still downloading it won't let the user do it. Here is the code that I'm using, adapted from phpbuilder.com: ?php $pathtofile = '\abs\path\to\file\'.urldecode( $_GET['link'] ); $download = 'http://www.somewhere.com'.urldecode( $_GET['link'] ); $type = urldecode( $_GET['type'] ); $size = filesize( $pathtofile ); header(Pragma: private); header(Expires: 0); // set expiration time header(Cache-Control: must-revalidate, post-check=0, pre-check=0); // browser must download file from server instead of cache // force download dialog header(Content-Type: application/force-download); header(Content-Type: application/octet-stream); header(Content-Type: application/download); header(Content-Type: $type); // use the Content-Disposition header to supply a recommended filename and // force the browser to display the save dialog. header(Content-Disposition: attachment; filename=.basename($download).;); /* The Content-transfer-encoding header should be binary, since the file will be read directly from the disk and the raw bytes passed to the downloading computer. The Content-length header is useful to set for downloads. The browser will be able to show a progress meter as a file downloads. The content-lenght can be determines by filesize function returns the size of a file. */ header(Content-Transfer-Encoding: binary); header(Accept-Ranges: bytes); header(Content-Length: $size); $fh = fopen( $pathtofile , rb); fpassthru($fh); fclose($fh); ? [after this the html content is displayed] Does anybody have any idea to allow for multiple downloads while another one was going on. Maybe some additional headers? I have tried adding headers before and after where I open the file for HTTP/1.1 200 OK and the corresponding headers. I have also tried using a simple meta refresh, but that doesn't work because it won't refresh until the page is entirely loaded. I am at a loss, I can't seem to find answer when I google it either. Maybe I'm just missing something. I don't know. Josh -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] file download using header
I am having some trouble making it possible to download a file using the header function. The problems are: (1) I get the dialog box to download the file, but for some reason the type of file isn't getting passed to the box, and (2) when I download a 4MB file it only seems to be getting 16.6KB. I haven't used header for this purpose before this, so maybe I am missing something. I Googled around and found the content-disposition type I thought I needed, I actually tried 3 different types (the file is a compressed zip file). I Googled around for tutorials on downloading files and still haven't found the answer to correcting my problem. Here is the code I am using, maybe a couple more trained eyes looking at this could help me out. ?php $download = 'http://www.usa-financial.com'.urldecode( $_GET['link'] ); $type = urldecode( $_GET['type'] ); $size = filesize( '/home2/www/usa-financial'.urldecode( $_GET['link'] ) ); header(Content-type: $type); header(Content-Disposition: attachment; filename=$download;); header(Accept-Ranges: bytes); header(Content-Length: $size); echo !-- $type \n $size \n $download \n --\n; ?

[PHP] Re: file download using header
Okay, I found a solution to part one of my questions by changing my headers, but for some reason I am still getting a fractional download of the file. Most commonly it's about 16.6KB of a 4MB file. The kicker is it says that it completed successfully. Here is the modified code: ?php $download = 'url/path/to/file'.urldecode( $_GET['link'] ); $type = urldecode( $_GET['type'] ); $size = filesize( '/abs/path/to/file'.urldecode( $_GET['link'] ) ); header(Pragma: public); header(Expires: 0); // set expiration time header(Cache-Control: must-revalidate, post-check=0, pre-check=0); // browser must download file from server instead of cache // force download dialog header(Content-Type: application/force-download); header(Content-Type: application/octet-stream); header(Content-Type: application/download); // use the Content-Disposition header to supply a recommended filename and // force the browser to display the save dialog. header(Content-Disposition: attachment; filename=.basename($download).;); /* The Content-transfer-encoding header should be binary, since the file will be read directly from the disk and the raw bytes passed to the downloading computer.

[PHP] Re: file download using header (SOLVED)
I found the solution, I ended up instead of using readfile, use fopen and fpassthru.

Re: [PHP] cache control with javascript
The it that you were asking about was the server. The javascript file is
actually a PHP file that produces the JavaScript that I need. I only have
one access to a database and a while loop to generate the code. Here is the
code pieces:
[code]
// already connected to the db
$sql = SELECT * FROM Customers ORDER BY LastName ASC, FirstName ASC;
$result = mysql_query($sql) or die(mysql_error());
while($row = mysql_fetch_assoc($result)) {
// generate the javascript
}
[/code]
The customer database can get potentially large so that this file could take
a while to generate. Currently there are only 300 records but I anticipate
many more. Does anyone have any recommendations that might speed this up?

Here is the situation:
I am creating a dropdown menu system that contains a customer list,
loaded from a database. This list is written to the javascript file
for the menu. The menu can be quite large as the data grows. What I
would like to do, is force it to be cached (unless of course the
user agent doesn't allow it) so that it doesn't have to make the
call to generate the file each time.
What is the second it in the last sentence above? A browser wouldn't
make the call to generate the javascript file each time.
I have searched through the php.net website and even through the
HTTP/1.1 protocols. I am continuing to look, but have not found a
definite answer as to whether or not what I am trying to do is
possible.
Just make sure that the javascript is on a separate file (i.e.
whatever.js) and that it's NOT being generated by your (php) script
each time. Then, call that file from inside your html/php page.

RE: [PHP] cache control with javascript
That really helped, I didn't think about generating the file that way. I have done other things like that, but sometimes it just helps when you get another set of eyes on the project at hand.

[PHP] PHP hosting with remote MySQL access allowed
I am in the process of developing a client side application that needs to speak to our remote databases. Does anybody know of a hosting solution that would allow me to have remote access to a MySQL database? I done some googling and found a quite a few hosting companies, but none of them that I have check have the information posted on their websites, so I had to submit an email question to them.

[PHP] SSL, PHP, MySQL
Hi all, I was wondering if anyone could direct me to some good tutorials on how to utilize PHP to access a MySQL database behind SSL. I have been searching PHPBuilder.com, PHPClasses.org, and hotscripts.com, and I can't seem to find any good tutorials for a beginner when it comes to SSL. I do have a fairly good working knowledge of PHP and MySQL so I'm not necessarily looking for a guide on that, I just need to know how to pass encrypted data back and forth. Here is the scenario: My client has a website in which a customer will be purchasing gift certificates online. They don't need a comprehensive e-commerce package, just simple information passed across a secure connection, such as: user names, passwords, credit cards and mailing addresses. We already have a MySQL db set up with the gift certificate package information. I just need to be able to store the customer information for retrieval later by the owners of the site.

Re: [PHP] SSL, PHP, MySQL
I will try on the PHP-DB newsgroup as well, but I wanted to let you know about a link I found which shows the integration of SSL with MySQL and PHP.

I am assuming that your Web server running PHP is running on one machine (SERVER A)and the MYSQL server running on another (SERVER B)outside of a common firewall? Is this accurate? If this is true, then I would presume that PHP on SERVER A could encrypt a datafile with MYSQL instructions and send it securely to SERVER B, but then who would un-encrypt it and feed it to MYSQL? You might want to look into other alternative like tunneling with SSH or 'stunnel'. I remember hearing some about it, but have not real experience with it. do a search on some MYSQL mailing lists for some insight.
