You need to send headers to tell the browser how to handle it see:
header(); or.. if it is a php file and you want the visitor to
see/download the source you would be better off giving it another
extension eg .phps or .txt etc or have a handler file that did a
readfile after sending headers.

Subject: [PHP] Make fil downloadable
I need to somehow make it so when a user clicks a link, then get
displayed the download dialogue for the file. The file is a .php file so
I'm not sure how this is done but I've seen it been done before. How can
you do this?
Thanks,

It's a dynamically created file the user downloads and uses later as a PHP
script. If I put header() in it, that would make it downloadable again when
the user uses it on his/her server, wouldn't it?

eg:
<a href="file.php">Download File Click Here</a>
Now in the file.php you have:
<?php
header("Content-type: text/plain");
header("Content-Disposition: attachment; filename=xxx.php");;
// now we read the real file
readfile('xxx.php');
exit();
?>
This won't put the headers into the downloaded file and remember to
change the xxx.php into the file
to be delivered and the xxx.php in the header to the name you would like
them to save as.
* the file.php in the top is not the real file but a script that reads
into the buffer the real file!!

I wanted it so the user downloaded the file to their PC like when you're
downloading a zip file or exe file from someplace like www.download.com...

I'm trying to get php compiled with mime magic, and it doesn't
appear to be working.
Here's my phpinfo page, showing the parameters I've used to
compile; it does show that I used '--enable-mime-magic' as
instructed in the docs at php.net:
http://horde.csd-bes.net/horde/test.php?mode=phpinfo (I need
mime-magic for the latest Horde).
My understanding is that there will be a section in phpinfo()
displaying mime magic settings when everything is good. It is not
there at this time.
When I do the configure/make/make install, there are no complaints.
Is this an extention that requires a seperate module file like
mysql's mysql.so file? If so, it's no where on my system. I've
googled to find something of the sort with no luck.
I know also that I have to have a reference in php.ini pointing to
the magic.mime file; my entry says:
mime_magic.magicfile = "/usr/share/misc/magic.mime"
and I have verified that the magic.mime file is actually in the
location.
How do I figure out what's wrong?
Thanks

I really doubt that browsers doesn't run the code that is in unload event of
the page because the window is closed. That would be a very bad thing. Isn't
it what the unload event is for? I mean to run code when the page is
unloaded, it doesn't matter if the window is being closed or the user is
going to another page. I think the browser should finish all the opened
window's unload code and only after that close the application really.
I made a quick test for it:
<html>
<head>
<script language=javascript>
function wait(msec){
var enter_date = new Date();
var enter_time = enter_date.getTime();
var leave_date = new Date();
var leave_time = leave_date.getTime();
while (enter_time + msec > leave_time)
{
leave_date = new Date();
leave_time = leave_date.getTime();
}
alert('unload test');
}
</script>
</head>
<body onunload="wait(5000)">
unload test
</body>
</html
It works fine for me in ie6 and mozila 0.9.6, it shows the alert message
after about 5 seconds.

You da man. Unload is perfect. If the problem he mentioned before prevents
the browser from finishing its communication with the server you can always
send a wait command with sufficient time for things to finish up. I'll
start testing in a live environment with it now. Thank you for the help.

You don't have to use the wait function, I just made it to show that the
browser will always wait till the script finishes it's job.

Hello.
We've used it to create demos. It does work, but is being surpassed by
other options (at the time we purchased, it was the cheapest option, but
it's not anymore).
They seem to have updated their site some - $150 for 'just' the
obfuscator is a bit much, and the obfuscation portion was,
I thought, pretty poor.
If you relied at all on globals, or ever used 'extract' on arrays
coming from form input, it was useless. We don't rely on globals,
but we do rely on form array extraction sometimes - completely
wasted when the system would 'obfuscate' your code. Reason being:
<?
echo $myName;
?>
becomes
<?
echo $uu7whfdsisdf;
?>
But if you've got a form with
<input type='text' name='foo[bar]'>
You can't do
<?
extract($_POST['foo']);
echo $bar;
?>
and expect it to work, because the obfuscation will turn it into:
<?
extract($_POST['foo']);
echo $uu7whfdsisdf;
?>
I wrote them and told them it was fairly pointless, atleast
for systems large/advanced enough that you'd consider wanting
to protect them in the first place.
They didn't seem to have much on their site before about
how to get new .so and .dll files for newer versions of PHP
(they bundle .so and .dll files for each version of PHP
- 4.1.0, 4.1.1, etc). Also, the support for working
'out of the box' with no need to fiddle with the php.ini
file was useful. Ioncube's encoder answer requires your users
to install the appropriate .so or .dll file in a particular directory,
or to edit php.ini - not as useful for giving out demos. Ioncube
is making an effort to move in that 'ease of use' direction,
but it doesn't seem to be there just yet.
Having said that, the ioncube answer offers a greater level of
security for the encrypted code - the sourceguardian stuff
is, last I checked, 'just' encrypted source code. zend and ioncube
package encrypted byte code. If someone decrypts zend-encoded
files, they'll only get bytecode. If they decrypt sourceguardian
code, they get the original code. This was how it was
last summer - they may have upgraded since then.
All in all, it's not bad. That the files now can be run on Windows
servers is a plus, but lack of a command line version to allow
for dynamic encryption from a server isn't all that good. If you *need*
that, you'll need to find something else. Why?
The 'time limiting' aspect, for starters - you can set a 'timeout'
for a particular date. Unless you put up a new trial file on a
site every day, you won't be able to offer '14 day' trials, for
a start. The file will timeout on date X, regardless of when the
user downloaded it. The Zend license manager is much more flexible in
that regard, but is overkill for most smaller projects.
Does this help at all?

Keep in mind the "Works out of the box with no changes to your server"
requires the use of the function dl()
according to the PHP docs;
dl() is not supported in multithreaded Web servers. Use the extensions
statement in your php.ini when operating under such an environment.
However, the CGI and CLI build are not affected !
I haven't tested wether it actually works with servers such as
IIS/Apache2, and given its not supported, perhaps it works, but could
have weird results after the so/dll has been loaded after the millionth
time.
user contributed notes off of the PHP site:
the function dl() is not supported on Multithreaded systems like Windows
XP. You need an external library for it, that has to be loaded when your
server does. If not, you will get a fatal error and the script will stop
parsing.

Good point - had forgotten that may have issues for some people.
However - in our case we've used 'protected' versions only for demos,
which people generally aren't running on production machines, but local
development environments, so issues of crashing or 'safe_mode' and
other issues have usually been of limited concern. But it is a good
point nonetheless, and isn't just a strike against SG, but ioncube as
well should the user not be able to edit the php.ini file.

I would suggest you try one of the following;
faqomatic http://faqomatic.sourceforge.net/, which is actually perl based
or phpFAQ
http://product.cybergl.co.id/dev/version.php?cmd=browse&product_id=15
or FAQbot http://mason.gmu.edu/~bhroleno/FB.html
or knowhow^2 http://www.linuxclass.de/kh2/
or piFAQ http://pifaq.sourceforge.net/
or StandardFAQ http://www.stampede.org/~drax/StandardFAQ/
or PHPWiki (http://phpwiki.sourceforge.net/) (Not a faq system, but it would
do the job)
when hotscripts fails, try sourceforge.
when sourceforge fails, try freshmeat.

Are you looking for something new, or something which suits your needs?
Not trying to flame here, but I didn't understand the sentence.
I think what the other poster was getting at is that if you searched and
can't find anything that meets your needs, do go ahead and write
your own tool. Yes, re-inventing the wheel isn't the best idea,
but your 'wheel' (what you want the app to be) doesn't exist,
based on your own searching.
If you'd searched Lycos for 30 seconds, I'd say search again. If you've
exhausted HotScripts, I'd say you've gone thru the majority of known
systems - certainly systems that had authors who were interested enough
to bother to register them in the first place.

Hello,
On 01/10/2003 01:51 AM, Nick Oostveen wrote:
As PHP becomes more accepted in the corporate world, it is only logical
that larger and more complex applications are going to be developed
using it. While there is an abundance of information out there about
making specific things work, there seems to be a shortage regarding the
big picture.
As such, my question is this: What methods and techniques can be used to
help design and build complex, medium to large PHP applications that are
not only scalable, but maintainable and extensible? I'm looking for
online references, personal experience and opinion and even examples of
open source code which you think demonstrate the above criteria on this
one. I think an extended discussion on this topic could be of great
benefit to everyone.
Obviously separating application and business logic from interface code
is a given, but what about other things? Are the object orientated
facilities of PHP currently worth really trying to take advantage of? If
so, what are you doing to take advantage of them? Are design concepts
such as design patterns relevant at this level? What frameworks, if
any, currently exist to assist in rapid, structured development, and
what specific benefits do they bring to the table?
Your concerns are the same that I had several months ago. PHP is indeed
fine for small applications but when it comes to large applications you
end up coding by hand many repetitive tasks that could be abstracted by
tools that generate the code for from conceptual definitions to save a
lot of development time.
One of the most frequent tasks that becomes one of the most development
time consuming is interfacing with databases to store and retrieve
application data.
I did some research to find what kind of tools exist to automate tasks
like database interfacing making it flexible enough to adjust to the
application needs and generate efficient code. I realized that there are
plenty of components for handling what I need that are usually named
persistence layers.
One of the problems that those components has is that most of them are
not for PHP. Another problem is that many of them tend to be too generic
and a try to do most of the things at run time.
So, I decided to develop a persistence layer generator application. It
would generate PHP (although mine can also generate Java and Perl) and
it would not generate code that applications may not need to avoid
generating bloatware made of code that most of the time is not needed. I
also would like to never need to deal SQL in any place.
Last month I finally released Metastorage after over 3 months of
development. It is a persistence layer generator application that takes
a XML based description of components made of classes . You just
describe the classes variables, relationships between classes,
validation rules and the declaration functions that you want to use to
store and retrieve the classes objects from persistence storage that is
currently a SQL based database.
From then on, Metastorage generate everything for you, including all
the code for all the classes and even schemas definitions and classes
for installing the database tables that are needed. The generated code
is database independent.
As a bonus, it also generates entity relationship like class diagrams in
UML that you can render in many image formats. This is usually very good
to document projects in such a professional way that impresses customers
and bosses.
The good part is that it reduces to minutes or hours, the work that
usually would take weeks or months to develop with hand written code.
Metastorage is Open Source is available here:

thanks alot guys, i have tried with this codes:

for($j=1; $j<=3; $j++)

<SELECT NAME="<?php echo "try[$i][$j]" ?>">
<OPTION value="1">One
<OPTION value="2">Two
<OPTION value="3">Three
<OPTION value="4">Four
<OPTION value="5">Five
</SELECT>
<?php
}
}
?>
<INPUT TYPE="submit" value="NEXT">
</FORM>
array2.php
----------
<?php
for($i=1; $i<=3; $i++)
{
for($j=1; $j<=3; $j++)
{
echo $try[$i][$j];
echo "<BR>";
}
}
?>
and the output are come out in the array2.php
since the output can printed out, means that this page (array2.php) can
receive these variable and we can send the values of these variable to
mysql.
thanks

from other posts further in the thread it looks like you aren't
ready to use https. that's too bad. that would really be the
right solution.
but since you must hash, one problem with hashing is, it is still
necessary to have the hash vary from one invocation to another.
otherwise, if the hash is the same every time the user logs in
(i.e., if all you do is take the password and run it through md5),
then anyone who can sniff the hash will be able to replay a login.
unfortunately, if you want the hash to be different from one
invocation to the next, then the password cannot be stored
on the server as a one-way hash. instead, it would be either
plaintext or encrypted on the server. this way, when you
want to send the hash over the internet, instead of just hashing
the password, you can generate a few extra characters. append
(or prepend) the characters to the password. then hash the
whole thing.
then, when you send the hash over, send the extra characters
too. on the server side, you would then take the password from
the database (or wherever), decrypt it (if it's encrypted), append
or prepend the extra characters, hash the whole thing, and
compare the hashes.

Hi,
I've got a problem to solve regarding binary data strings, which is an area
I don't have a lot of experience in. If anyone can help, I would be
grateful.
Here's the problem in a nutshell:
I am getting a binary string from a third-party server that I need to encode
into a PNG image. The string arrives double-quoted, so double quotes which
may occur in the binary string have been escaped. I need to parse through
the string and extract only the PNG data, and convert whatever has been
escaped into usable data.
I cannot control the output from the third-party -- I've got to deal with
what they're sending. (I would much rather have them send a base64 encoded
PNG, but unfortunately I'm not able to influence their methods.)
Here's the problem as described by the API I'm working with:
____________________________________________________________________________
The rule for encoding the PNG image in the returned buffer was designed to
eliminate certain illegal characters (byte values) by replacing them with an
escape sequence. Those values that are not allowed include:
* NULL (0x00 hex)
* Double Quote (0x22 hex)
The percent character '%' (0x25 hex) is used as the escape character, and
therefore it must be replaced where it occurs naturally. Whenever a
disallowed character or the escape character '%' is encountered, it is
replaced by the escape character '%' (0x25 hex) followed by two characters
comprising the hexadecimal numeral representing the value of the character.
For example, the NULL character (0x00 hex) is replaced by three characters:
* '%' (0x25)
* '0' (0x30)
* '0' (0x30)
The percent character 0x25 is replaced by three characters:
* '%' (0x25)
* '2' (0x32)
* '5' (0x35)
The algorithm for decoding the PNG image in the returned buffer is as
follows. Read bytes from the buffer one at a time. When a byte read is not
equal to the '%' character (0x25 hex), pass it through unchanged. When a
byte is read that is equal to the '%' character (0x25 hex), read an
additional two bytes, which will each take a value from zero (0x30 hex)
through nine (0x39 hex) or 'A' (0x41 hex) through 'F' (0x46 hex). These two
bytes are interpreted as a character representation of a two-digit
hexadecimal numeral ranging from 0x00 through 0xFF. The single byte having
the integral value represented by that numeral is appended to your output.
For example, when the 3-byte string '%22' is encountered, '"' (0x22) - the
double quote character - is passed out. When the 3 bytes '%00' are read, the
null character is written.
In essence, the developer will need to take the data received and store it
in a buffer, which has sufficient memory to hold the entire data stream.
Once the data has been received, the program must call a function similar to
the one described below in order to parse the data in the buffer and extract
only the PNG image data.
____________________________________________________________________________
The API then presents an example in C, which I've tried to translate into
PHP as best as I can. It's pretty close, I think -- but I'm still not
getting a PNG out when I'm done.
Here's what I've written, based on the C example:
____________________________________________________________________________
$buf = [binary data received];
$len = strlen($buf);
$out = '';
for ($c = 1; $c < $len; $c++) {
$data = $buf{$c};
if ($data != '%')
$out .= $data;
if ($data == '%') {
for ($e = 0; $e < 2; $e++) {
$c++;

I'm just getting a blank screen at the end here -- not a PNG image.
Can anyone with more experience dealing with binary data offer any
suggestions? I'm at a loss and would appreciate the help! I would be happy
to send the example C code from the API if that would be helpful.
Thank you!

Well, I'm always trying to make it harder than it needs to be. A few more
hours of research yielded this solution:
$out = preg_replace("/\%([0-9][0-9])/e", "chr(hexdec(\"0x$1\"))", $buf);
Header("Content-type: image/png");
echo $out;
... Worked like a charm.
If anyone can see any problems with this solution, I would be interested to
hear them!
Thanks,
Clay

Hi all,
So I have a session variable; but with register_globals active on the server
I'm hosted at (no way to turn it off), just checkng for "$varX" in my script
could retrieve the session variable, a GET variable with the same name, or a
POST variable with the same name - and as a security concern, someone could
use a GET request (http://somehost/mypage.php?varX=0) to spoof the script
into thinking that "varX" is the wrong value.
So, is there any way in a script to specify that I want to retrieve the
value stored in the registered session_variable("varX")??
Thanks,
--Noel

Nevermind, just found the $HTTP_SESSION_VARS array...
Thanks anyways! Take care,

FYI:
Don't like auto register globals ... try the following at the beginning
of your script.
ini_set ('register_globals','Off');
Works for me places I'm hosted at.

Hello List,
a simple problem turned out to be not so simple as I thought.
Here the situation:
main.php4
|
+-include() mainhtml.php4
|
+-include() functions.php4
|
+a function does include() languagevars.php4
I can see the included $vars from languagevars.php4 in functions.php4
but not in main.php4.
Using "global $var" just seems to work top->down but I'm not able to
bring the $vars up to the main.php4 or to the mainhtml.php4.
This time, I just wanted to write not one scary large PHP4-Page with
around ~100kb in size. But I'm really stuck - all the books, pdfs and
web information just want to bring the $vars down.
Or is there just a failure in thinking?!
Any hint is highly appreciated.
Ben :)

what does debug_phpinfo.php read to get its information?
When I run debug_phpinfo.php in my browser it says version 4.2.3
But when I execute php -v at the command line I get 4.0.4pl1
