Put this line at the top of the script that the form posts to...

print '<pre>'.print_r($_POST, true).'</pre>'; exit;

That will display the contents of the $_POST array and you should be able to
figure out where everything is.

By the sounds of it the posted values are actually in $_POST['Post Array']
but use the above line to be sure.

I can't remember the syntax but I'm sure there is an easy way to get one
PDF to reference another and distil it into one... I remember this from
way back when (and using Adobe tools which is why the phrase distil was
used...) and it could be completely irrelevant from the context of PHP
functions which I'm not familiar with personally.... so in short, I
can't help :/

Failing that you could try asking Henry's cat. You must know Henry's
cat? He knows everything about nothing and not to much about that. So if
you know someone who know what he knows then you must know Henry's cat....

Hello Thushara:

My guess is that your .gif file isn't actually a GIF image (but jpeg, bmp,...).

If you have access to SSH/command line try running
file 
/home/thushw/mocha_src/LiveMocha/trunk/src/wwwroot/app/webroot/img/new/button-middle.gif
and see if it's really a gif, if you don't have access to above, open
the image with any text editor, and see what the first 3 letters say..
If it's an GIF image, it says GIF (GIF89 probably)
if it's an JPEG image, it says something like ÿØÿà
if it's an BMP image, it says BM (BM6)
and if it's an PNG image, it says ‰PNG

I hope this helps you..

Hi Tijnema
It does appear to be a GIF. See output from file command below:
for now, to get by I have copied over a libgd.so verion from a working
centos installation over /usr/lib/libgd.so
thanks,

Thanks for offer your help.
I will try to explain in details what I did.

First of all, on file php.ini I removed the comments for the line below:

extension=php_imap.dll

After that, I have followed the Gmail instructions to enable POP in my Gmail
account as below:

1. Log in to your Gmail account.
2. Click Settings at the top of any Gmail page.
3. Click Forwarding and POP.
4. Select Enable POP for all mail.
5. Choose "Keep Gmail's copy in the inbox" when messages are accessed with
POP.

When I run the simple code below:

<?
$mbox = 
imap_open('{pop3.gmail.com:995/pop3}INBOX<http://pop3.gmail.com:995/pop3%7DINBOX>',
'<my_login>@ gmail.com', '<my_pass>');
print_r(imap_alerts());
print_r(imap_errors());
$num_mens_not_read = imap_num_recent($mbox);
imap_close($mbox);
?>

I get these errors:

Warning: imap_open(): Couldn't open stream
{pop3.gmail.com:995/pop3}INBOX<http://pop3.gmail.com:995/pop3%7DINBOX>in
c:\arquivos de programas\easyphp1-8\www\index.php on line 2
Array ( [0] => Host not found (#11001): pop3.gmail.com )
Warning: imap_num_recent(): supplied argument is not a valid imap resource

Warning: imap_close(): supplied argument is not a valid imap resource in
c:\arquivos de programas\easyphp1-8\www\index.php on line 6

And, when I run the simple code below:

<?
$mbox = 
imap_open('{pop.gmail.com:995/pop3}INBOX<http://pop.gmail.com:995/pop3%7DINBOX>',
'<my_login>@gmail.com', <my_pass>');
print_r(imap_alerts());
print_r(imap_errors());
$num_mens_not_read = imap_num_recent($mbox);
imap_close($mbox);
?>

I get these errors:

Warning: imap_open(): Couldn't open stream {
pop.gmail.com:995/pop3}INBOX<http://pop.gmail.com:995/pop3%7DINBOX>in
c:\arquivos de programas\easyphp1-8\www\index.php on line 4
Fatal error: Maximum execution time of 30 seconds exceeded in c:\arquivos de
programas\easyphp1-8\www\index.php on line 4
Notice: (null)(): POP3 connection broken in response (errflg=2) in Unknown
on line 0


This second code looks like ok for me, but for some reason I get this time
out. Do you have any idea what's going on? Did I miss some configuration?


Thanks in advance.

Array ( [0] => Host not found (#11001): pop3.gmail.com )


So pop3.gmail.com doesn't exist.


<?
$mbox = 
imap_open('{pop.gmail.com:995/pop3}INBOX<http://pop.gmail.com:995/pop3%7DINBOX>',
'<my_login>@gmail.com', <my_pass>');
print_r(imap_alerts());
print_r(imap_errors());
$num_mens_not_read = imap_num_recent($mbox);
imap_close($mbox);
?>

I get these errors:

Warning: imap_open(): Couldn't open stream {
pop.gmail.com:995/pop3}INBOX<http://pop.gmail.com:995/pop3%7DINBOX>in
c:\arquivos de programas\easyphp1-8\www\index.php on line 4

This second code looks like ok for me, but for some reason I get this time
out. Do you have any idea what's going on? Did I miss some configuration?


Line 4 is

$num_mens_not_read = imap_num_recent($mbox);

so it's taking too long to work out how many are recent.
How many unread messages are there in your account? How many messages in total?

Hi guys
Im helping a friend with hes internet site, and I have found this regex email validation regex on the internet:
var filter=/^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a- z]{2,6}(?:\.[a-z]{2})?)$/i; 
if(!filter.test(email)) {
        return false;
}
It works fine, but my friend strangely enough has users with special danish letters (æøåÆØÅ) in their email address, and that it does not accept. Regex is black magic to me, I have tried to modify it in different ways, but with no luck.
I know its not PHP specific (its JavaScript), but maybe one of you can help me anyways? 

Best regards
Søren

--- Begin Message --- I'm working on a intranet site that uses an LDAP server to authenticate users and then a integrated CMS (kind of like a wiki with security features so only certain people can post things or upload files) runs the whole thing. (The CMS is custom built with PHP).
I've got a need to make certain files secured so that if someone uploads a file they can specify that no one except certain people can view the file. I've got all the security features set up, what I need to do is come up with the best way of securing those files. Obviously the link won't show to those files if the user doesn't have access to it, but I'm worried that someone might know the link and be able to access the file that they are not supposed be able to see.
This doesn't need to be NSA level security, but I do need to protect against some computer savvy users. So, I'm pondering the following ideas for hiding those files. Any insight on the best method would be appreciated:
1) Write secure files to MySQL as a blob (only secure files would be written there)
2) Write secure files to the level below the web root and come up with a way of copying the files over to a temporary directory for access, then delete the files as soon as they are accessed.
3) Use Unix passwords to protect a folder in the web level and then the CMS knows the password and can pass the password for access (so that the user doesn't know this password, but the CMS does).
4) Some various forms of link obfuscation, where the CMS goes through all the secure files once an hour or so and rewrites the file name with a random string. 

5) Or ???? I'm open to suggestions.
Thanks.

You can easily force all file access to pass through a PHP script -> just do this kind of thing:
- Fetch file information from a get variable, like file.php?fileid=12345 (or even file.php?filename=somefile.bin) - Check if the user is allowed access to that file (yes: continue, no: display an error) 

header("Content-Type: " . $file->getContentType());
readfile("/path/to/secure/" . $file->getFileName());
Then just make sure that the "/path/to/secure/" (as in the example above) is not readable by web users by some means.

Personally I don't like this strategy but it is always a hot topic on
this list. I don't mind storing a few small images in the db but when
you start to store >200-300Megs it just complicates your database backup
strategy. If you use snapshot-based filesystem level backups (e.g. using
LVM) then this is mitigated but still has many downsides IMO.

Nah... seems to complex.

Still not 100% secure and overly complex IMO.

I think you are kind of on the right track with 2 but there is no need
to do this copying.

Simply put all requests for your file through a PHP script. This can be
done with PATH_INFO or mod-rewrite in Apache (just google this for examples.

You PHP script will then check the access credentials of the user (e.g.
a logged in Session) and then output relevent cache headers (again
google) before issuing a Content-Type header with the correct mime type
for the file in question along with the Content-Length header with the
physical size of the file (not strictly speaking necessary but nicer for
the client) before simply calling
"include('/path/to/file/not/in/webroot.ext') to push the content to the
user.

Hope this helps.

echo 'Your software provider sucks eggs. Get a better browser.';

heh ...
I just did precisely this (the script, not the "sucks eggs" comment) for a project i'm working on. There's a file store above document root and a script that does user validation, then reads the top dir of the file store and display links for each directory or file in there (of course, they're not direct links), letting the user drill down as far as it goes. 


What exactly is in the var $extension?
header("Content-type: $extension");


Don't do this:
$file = file_get_contents($file_path);
echo ($file);

Do this instead:
readfile($file_path);
exit;


Here's the business end of my script:

-- snip --
header ('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header ('Content-Type: application/octet-stream');
header('Content-Transfer-Encoding: Binary');
header('Content-length: ' . filesize($filepath));
header('Content-disposition: attachment; filename="' . basename($filepath) .'"'); 
readfile($filepath);
exit;
-- snip --
Note that i'm not trying to give the option for the browser to hand off the file to a "helper application" or plugin. This script is for downloading only, hence no MIME type and the "octet-stream' & 'attachment'.
I just checked another project where i did pass the MIMIE to allow for the file to open in Adobe Reader, MSExcel, etc. You also might want to add these two with your no-cache header: 

header ('Expires: Mon, 1 Apr 1974 05:00:00 GMT');
header ('Last-Modified: ' . gmdate('D,d M YH:i:s') . ' GMT');

I seem to remember that it was IE that wanted these in order to play nice.

Hej Søren

to get it to work, you need to be in the Danish locale, otherwise "æøå"
won't be recognised as being word-characters. In javascript, I'm not
sure, but maybe you have to use UTF-8?

have you looked into http://php.net/filter functions?

not sure if those are locale-friendly or not. if(filter_var($foo,
FILTER_VALIDATE_EMAIL)) {} has worked for me. i don't use any extended
characters though. but changing your locale in PHP might allow it to
work.

Untrue.  If a property exists, then it is used as-is and 
__get()/__set()/__isset()/__unset() are never called.  The property behaves 
normally, as if those methods were not defined.  If they're not defined, the 
magic methods do whatever they do, which can include adding more properties 
to the object if appropriate (thus bypassing the magic methods in the 
future).

Hi everybody!

I'm working on building a few "similar" Dev machines on different OSs.

I've finished a source build of PHP_5_2 branch cvs on a FreeBSD box.
Went smoothly!

I've tried the same on an OSX box.  It's got mostly the same
built-from-source prereqs in place as the FreeBSD box.

But, building PHP_5_2 on OSX keels over at,

        ...

        collect2: ld returned 1 exit status
        make: *** [libs/libphp5.bundle] Error 1


I don't know exactly why MySql libs are involved here.  I'm NOT
configuring the build for any MySQL-related modules to be built; I'll
do those separately as extensions, later.  During ./configure output,
I make sure I see

        ...
        checking for MSSQL support via FreeTDS... no
        checking for MySQL support... no
        ...
        checking for MySQLi support... no
        checking whether to enable embedded MySQLi support... no
        ...
        checking for MySQL support for PDO... no
        ...

The only source I've been able to find for the -lmysqlclient_r references is,

        apu-1-config --libs
         -ldb-4.6   -lsqlite3  /usr/local/mysql/lib/mysql/libmysqlclient_r.la
 -lexpat -liconv

Which probably gets picked up from PHP's ./configure,

        ./configure --with-apxs2=/usr/local/apache2/sbin/apxs ...

I'm guessing here, but I figure this 'bad magic number' biz is an
OSX-only thing.  About which I don't know a bunch :-(

Any suggestions as to what to do here?

Thanks a lot! :-)

Ali
