[PHP] http authentication through PHP
What is the easiest way to access a page that is protected by HTTP basic authentication through PHP? In other words, I have a PHP page that will get the username and password off a database and will then login through HTTP authentication to access a second page (say an HTML page).

[PHP] alternative to protecting files through http auth.
Is there no other way to protect your (non PHP) files than through authentication? I've been trying to set up a system that will protect files. Those trying to access the files would only be able to do so after entering their email address. So I set up a form that submits the email to my database. But then the problem is: how to access the files? I could just use http://username:password/test.com/test.jpg method, but then what would be the point of trying to protect the files in the first place? It would simply be the same as with holding the link to begin with. So is there an alternative to using http basic authentication to protect files? Or is there a simple way to authenticate the pages themselves without using something like Manuel Lemos' "PHP HTTP class"?

It actually does not work.
Could you explain what, exactly, does not work?
I am trying to load a PDF file. I've tried
to load it from a protected directory loading it with headers, but this
fails if the protection is on. Does this make sense to you?
The above outlines a scheme which is workable. Could you describe the steps
you took to implement said scheme which lead you to the conclusion that "It
actually does not work" ?
Yes, sorry. Here is the code: $file =
'http://miningstocks.com/protected/archive/Dec03PostPress.pdf'; //now
view the PDF file header("Content-Type: application/pdf");
header("Accept-Ranges: bytes"); header("Content-Length:
".filesize($file)); readfile($file); I can send the rest if necessary.
You can see the results yourself of this:
http://miningstocks.com/enteremail.php (just enter [EMAIL PROTECTED] for an email
address). Yet, when I have changed the $file to hold a path that is not
protected through http auth. it works perfectly fine and loads the file.

[PHP] authentication problems!
I am about at my wits end trying to find a good solution to this problem. I've asked various portions of this question to this mail list and still have not found exactly what it is I am looking for, but here it goes. I'm looking for a way to protect my files (this would be pdf files, image files, etc...other things then text/php files) so that for someone to see a current file they will have to enter in their email address and name. Seems fairly simple, and yet I can not figure out how to do it. I've been told of the following alternatives: Protect the files with HTTP auth (basic, or use SSL if very paranoid), then, after entering the info into a database: 1. just link to http://username:[EMAIL PROTECTED]/protect/file.pdf (either directly using html, or use headers). The problem: if using HTML, the username & password is easily seen. If using headers, this does not work (it is not seen as a PDF file) - my best guess is that the auth headers get passed along and so it does not work. Of course, I can load a PDF using headers if the file is not in a protected directory without any problems at all. But then again it wouldn't be protected to begin with. 1.b. It was later suggested that I could link to http://username:[EMAIL PROTECTED]/protect/file.pdf and use an apache rewrite statement to change every protected file to exclude the username & password. But I've posted to an apache group and they have said that this CAN NOT be done. 2. link to something outside of my httpdocs directory. Unfortunately, I am on a shared server and do not have a private folder (or at least my _private directory which is contained with httpdocs will not work - I get the same problem that I do with authentication - it does not recognize the file as a PDF at all). 3. use a prebuilt class (such as snoopy or Emanuel Lemos). This looks as though it is the only option available to me at this time, but It doesn't look as though it as a good one as it will add a lot of code to something that seems as though it should be VERY simple, and it means that I will have to go through the documentation to use this.

Re: [PHP] authentication problems!
by "using HTML" I meant, typing the address in to the broswer as
http://username:[EMAIL PROTECTED]/protected/file.pdf or as using the
HTML: http://username:[EMAIL PROTECTED]/protected/file.pdf">Link...
or using the header: header("Location:
http://username:[EMAIL PROTECTED]/protected/file.pdf");
>also, there is no problem retrieving a pdf after passing http basic
authentication (I just double checked this on a client's site and was
appropriately prompted with a pdf handling dialog box after I
authenticated).
Of course there is not problem if the user is entering the information
him or her self. But just using this code:
$file = 'http://miningstocks.com/protected/Dec03PostPress.pdf';
//now view the PDF file
header("Content-Type: application/pdf");
header("Accept-Ranges: bytes");
header("Content-Length: ".filesize($file));
readfile($file);
from a PHP page where no authentication has occured does not work at all.
Let me say, if this is not clear, that I do not want unique usernames
and passwords for users. I want one username and password that WILL
NEVER BE SEEN by the user.
The way that I had planned was to keep ONE username and password which
would allow access to all the files in a MySql database. After the user
entered his name and email address, the username and password would be
fetched off the database, and then authentication would occur with this
username and password and the user would be served the file. The
authentication would be completely transparent to the user. But the
different ways to authenticate transparent to the user either do not
work or reveal the username and password (making it pointless to even
protect the files in the first place).

also, there is no problem retrieving a pdf after passing http basic

now, http basic assumes that the id/pw are in a file/database/etc. the
password is generally encrypted (des or md5) but can be in clear text.
so, for this to work, you'd probably need some type of registration
page that will store the id/pw info that the apache server will query
against. [i strongly recommend using a database, not a file, due to
file locking issues.]
other approaches to this general issue include a URL mapping scheme.
e.g., the public URL would drive the user through a one-time
email/name collection process. when the user passes that they are
served the document from the actual storage location. they can be done
in a way that the true document URL is never shown. obviously you'd
have to do this in a way that would give the fake URL as a .pdf so
that the client will handle things correctly.

Yeah, i think i mentioned the same thing(or was going to :/ )
you should be able to use the local filesystem, and reffer to it relatively!
and then you can stream it and you wont need any authentication, and noone

Did you not read my reply to your previous thread about this? Use a local
filesystem path to read the file.

[PHP] Extra byte added to PDF streaming file
I'm using this code to stream a PDF file:
$file = $_SERVER['DOCUMENT_ROOT'] . "/file.pdf";
simple_streamfile($file);
function simple_streamfile($file)
{
$fp = fopen($file, 'rb');
// send the right headers
header("Content-Type: application/pdf");
header("Content-Length: " . filesize($file));
// dump the file and stop the script
fpassthru($fp);
fclose($fp);
exit;
}
It appears as though some readers (such as adobe acrobat) can read this
file fine yet others (such as the program gv in *NIX) cannot read it.
The reason for this is that somehow a hex 0A is added before the inital
%PDF-1.2 which marks the start of the PDF file causing some readers to
not recognize it as a PDF file. Is there anything in this code which
could possibly (always) cause an extra byte (0A) to be added before the
real start of the file? And no, the file is not corrupted (I've
already tried that) - this only happens when it goes through this
script, and not loaded directly as example.com/file.pdf.

[PHP] opening Adobe pdf's
On my site I use these two blocks of code to open protected files. I
can open the files fine, and so can plenty of others. The problem is
that at least one person complained that they couldn't open the file.
This is what they had to say:
It opened Adobe, then an
Adobe Reader window opened that stated "There was an error opening this
document. This file cannot be found."
So that must mean that the streamfile($file) function (see below) did not return false,
otherwise the message would have been "file was not found. please send [EMAIL
PROTECTED]"
Does someone know what's going on here? Since I am not experincing this problem first
handed, I really have no clue. Also, shouldn't this person get prompted if he wants
to save it or open it with Adobe Acrobat?

Becareful sending this header. The client can get confused and

expecting different results than the whole file.
Which header? The "Accept-Ranges" header? Should I just not include it?

Yet in IE if I choose to 'open' the file instead of saving it, it asks me that question twice. I'm wondering if that will cause an error on an older version of i.e. or any other browser.
On php.net, it gave this code:
|// open the file in a binary mode
$name = ".\public\dev\img\ok.png";
$fp = fopen($name, 'rb');
// send the right headers
header("Content-Type: image/png");
header("Content-Length: " . filesize($name));

basically the same code, but without an fclose(); could this be doing it?

Subject: [PHP] path problems
I have the following file:
http://domain.com/archive/newsletters/Dec03.pdf
For some reason this works: filesize('archive/newsletters/Dec03.pdf');
but this does not: filesize('/archive/newsletters/Dec03.pdf');
nor does this
filesize('http://domain.com/archive/newsletters/Dec03.pdf');
For some reason this works:
readfile('http://domain.com/archive/newsletters/Dec03.pdf');
but this does not: readfile('/archive/newsletters/Dec03.pdf');
nor does this: readfile('archive/newsletters/Dec03.pdf');
Can someone explain this to me?
Thanks for all the help,
Scott Taylor

Re: [PHP] path problems
Yes, the error I get is a pop-up box saying "This is not a valid %PDF file"
Here is my code:
$file_two = 'archive/newsletters/Dec03PostPress.pdf';
//now view the PDF file
header("Content-Type: application/pdf");
header("Accept-Ranges: bytes");
header("Content-Length: ".filesize($file_two));
readfile($file_two);
Now I would think that I wasn't using the correct headers or that the
file didn't exist or something of that nature, but since I get no error
with the full url, I have more or less figured it was problem with
loading a file from the local file system instead of the file itself
being corrupt, etc.
Thanks for the help,
Scott Taylor

I understand all of the file size ones. What I really don't
understand is why neither of the following examples work:

How does it not work?
Errors, anything?

And no, that doesn't work either. And on another note: the exact error is "File does not begin with '%PDF-' " I believe this would be the same error you would obtain if your tried opening a non-pdf file in adobe acrobat.

[PHP] extra breaks in sent out emails
I am entering some text into a webpage, then using $_POST on the next page to recieve it. It then should email the $_POST to an email address. The problem that I am encountering is that I am getting an extra line break on every line. If I enter a b into the textarea (which is the variable through POST) and do a character count it only shows 3 - the a, the \n, the b. Yet in the email address it comes out as: a b Why is this? BTW: I am on a windows computer but the server is a unix server. Best Regards, Scott -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: extra breaks in sent out emails
on Page One a b On Page Two: $to = $row['email_address']; $body = stripslashes(trim($_POST['email_body'])); mail($to, $subject, $body, $headers); What I really don't understand is why there are any line breaks at all, because the trim is supposed to take out all \r & \n 's. Is there another type of line break? Best Regards, Scott Taylor -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: extra breaks in sent out emails
Thank you Ben. Using either str_replace("\n", "", $string); or
str_replace("\r", "", $string); solves the problem. My guess is that
when I submit the data there is both the \r and the \n in there (for
there showed 2 white space characters in between the broken text
lines). My guess is that the server converts all \r's into \n's, and
for this reason when a piece of mail goes out it has two breaks instead
of one.
Best Regards, and thank you for the help,

trim() actually only strips whitespace (including \r and \n) from the
beginning and ending of strings. See http://www.php.net/trim for more
information.
If you want to completely remove line breaks from your string, use
str_replace() to do something like: str_replace("\n", "", $string);
and str_replace("\r", "", $string); See http://www.php.net/str-replace
Finally, have you tried echoing $body just before the message is sent
so that you can see exactly what is being sent to the mail() function?

[PHP] time delay function?
I am wondering if there is a time delay function, one that will cause the program to be inactive for a number of seconds (something like delay(10) ). I am doing this because I am setting up a mass mailing program (this is not spam), and I don't want to be targeted as spam.

[PHP] odd acrobat reaction to streaming files
I have been using a php file to stream pdf (and various other sorts of
files)... Here's my code.
if ($extension == ".doc"){$type = "application/msword";}
else if ($extension == ".pdf"){$type = "application/pdf";}
else if ($extension == ".exe"){$type =
"application/octet-stream";}
else if ($extension == ".ppt"){$type =
"application/vnd.ms-powerpoint";}
else if ($extension == ".xls"){$type =
"application/vnd.ms-excel";}
else if ($extension == ".xml"){$type = "text/xml";}
else if ($extension == ".zip"){$type = "application/zip";}
else if ($extension == ".txt"){$type = "text/plain";}
else {
$type="application/octet-stream";
}
header("Content-type: " . $type);
header("Accept-Ranges: bytes");
header("Content-Length: ".filesize($file));
readfile($file);
?>
And so this worked perfectly well when I did something like this:
loadfile.php?file=name.pdf (where name.pdf is the file I am loading and
loadfile.php is the name of the script). But
loadfile.php?file=directory/name.pdf (when launching Adobe acrobat)
would give me the error 'File Does not begin with '%PDF' ".
I was able to add this header line:
header("Content-Disposition: attachment;
filename=".basename($file).";");
which forced the user to be prompted if he wanted acrobat to be loaded
or to save the file. Both options worked flawlessly.
So why did it not work before I added this header line? Is it a flaw in
Adobe Acrobat?

Scott Taylor

[PHP] virtual() include path problems
I've been trying to use virtual to include a .shtml file that is outside
of my current directory (one level up). I've tried the following:
a) virtual("../header.shtml");
b) virtual($_SERVER['DOCUMENT_ROOT'] . "/header.shtml");
c)
virtual("/usr/local/psa/home/vhosts/miningstocks.com/httpdocs/header.shtml/");
b & c should be equivalent, because $_SERVER['DOCUMENT_ROOT'] should be
the same as /usr/local/psa/home/vhosts/miningstocks.com/httpdocs. With
that in mind, both b&c do not work at all. But a does work. Is virtual
not supposed to use absolute paths? The documentation on php.net
doesn't say either way, but for the include() fuction it says that it
should work...

[PHP] 404 Header Problems
I'm trying to issue a 404 header on one of my pages. But it does not redirect. I figured, with many function calls before it, that it might be outputting something to the screen before the header() command was issued. So, I tried issuing a 404 header from a new page, consisting of this code: or But neither of these work. Notice how there should also be no ouput to the screen before the header is closed. I've also tried: which gives the same results. The results are this: an output of . I'm on a large shared server, and my guess is that when there is a bug with some code in php, the server chooses to ouput this instead of the actual error code(s). I've experienced this many times when I upload a page and there is a simple syntax error such as one semi-colon missing from a statment. This is probably so that the server doesn't get hacked. If I try to issue both commands, in either order, I get this: Not Found The requested URL /cgi-sys/php.cgi/testing_server/404_error.php was not found on this server. Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request. Sowhat's going on here? Am I to conclude that the 404 header does not work, and that I should just use a Redirect: header() to my 404 page?
