Ajay, try changing your mpEntity to:

new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE)

See if it makes a difference.

[Ajay Garg]

Hi Aziz.
Thanks for the reply.

Unfortunately, making the change suggested by you does not make any
difference :(


Sorry, Thanks and Regards

No, connections are not shared between PHP processes. Nothing is shared between

Who's valuation of your time actually matters? Yours, and yours alone.

Therefore:

Life: n years
Time I can benefit from my life: n years

n years / n years = 1

*hoorah*

Your time is the most precious commodity you have.

Whether you use a framework or not you will (hopefully) reuse code between 
projects. If you choose to make part of that reused code one of the many 
frameworks that exist, you need only do one thing to ensure it continues to be 
worth using: how much of your time do you spend battling against the 
restrictions of the framework? If that's sufficiently low then using that 
framework is probably a good thing. If a significant portion of your time is 
spent battling the framework it's time to make a change.

Also remember that the only person who can truthfully judge whether you're 
"wasting time" is you, unless you earn money by selling your time to someone 
else in which case they have some right to decide what constitutes a waste of 
the time for which they're paying. I found the experience of writing my own 
framework to be hugely beneficial to my future productivity, but I might have 
struggled to justify spending the extra time it took to my employer at the time.

A persistent connection is closed when the PHP process ends, or it gets 
disconnected by the server-side or due to a network error. Attempting to 
explicitly close a persistent connection will do nothing without complaining.

Is there any other way to do it? I've been programming since 1975 and
that's what I was taught and that's how always do it.

Was it Brian Kernighan who said the 3 rules of programming are:

1. Keep it simple.
2. Build it in stages.
3. Let someone else do the hard part.

Agreed.

Plus, there are many date functions provided by MySQL that are easier 
(possibility faster) than what you can do in PHP.

Check these out:

Re: [PHP] Algorithm Help

[German Geek]

You don't need to maintain the history of which kids stay where unless you
want to for other reasons. You just need to find the children that have
staid the least amount of time together, which this approach would do for
you.

So, when 4 children stay together you say
1 together with 2
1 together with 3
1 together with 4
2 together with 3
2 together with 4
3 together with 4

and that's it. And then you can find the ones that staid together the least
amount of time.

Re: [PHP] Algorithm Help

[Ayush Ladia]

Hi,
Indeed making and maintaining the graph looks like the best approach here
to tackle this problem , but what does not seem clear to me is this --
 "Suppose a family can host 5 children , then you need to find the set of 5
such nodes out of the total no. of nodes(assume 10) such that the total
weight of all edges connecting the 5*4 nodes is minimum " ,
how do you go about finding this set once you have constructed and
maintained this graph and what will be the complexity??

Yes, I was going to ask, why are you storing your dates as strings?
MySQL has a perfectly good DATE type. It's also generally faster
comparing dates within a MySQL query than PHP code.

I'm not sure exactly what it gets compiled to, but I also don't see why it 
matters. All that matters is that content outside of PHP tags will simply get 
echo'd.

  Hi, Jim


Never mind my last paragraph ... I was thinking the wrong way of what you
wrote earlier.

I haven't tested it properly in every detail, but from the perspective of
what I know it's like you wrote.

The file that's mentioned as "php.ini" is the main configuration file of
your php-installation. It may be, that the user-ini file was renamed to
"php.ini" as well, but if you read about "php.ini", they always mean the
configuration-file that you see listed in the output of phpinfo() as
"Configuration File (php.ini) Path".

* You can rename the user-ini file by changing the user_ini.filename
setting in the php.ini file (as written on the page I linked you to)

* The php-settings are restored after/before each script-execution

* The manual doesn't catch if a user-ini file was found ... just that it
bubbles up to the document_root. Maybe the configuration found in user-ini
files is merged, or just the first file is taken.

* I don't know what happens to configuration you apply f.e. in nginx ... I
know neither when settings in php-fpm are applied ... that's something
left
for testing, or until somebody finds the documentation explaining it (I
know there is one ...), but I guess they're applied after the php.ini and
before the user-ini files.
Examples are listed here:
http://php.net/manual/en/**install.fpm.configuration.php#**example-60

* What you set using set_ini() is just applied for the rest of the
currently running script.

Bye
Simon

  I understand most of what you wrote and agree all except for one thing.

  You keep using the name "user.ini" and I asked for clarification on this
earlier.  Do I have to create files named EXACTLY that way, or are
"php.ini" files correctly named?

Hi, Jim

You can define the name for this file your configuration (php basic
configuration file or in the webserver, calling the cgi/fcgi script).

The configuration is called "user_ini.filename", and it's default value is
set to ".user.ini". Of course, your provider (or you, if you're the
administrator of the php-instance) may changed this setting to something
like "php.ini". Then the php-process will search for a "php.ini" file in
the directories a user-ini file is searched in.
When talking about configuration files, this may be misleading, as the
basic configuration file is refered as "php.ini" over all in the
documentation.

I don't believe, that the PHP process would search for a file called
"php.ini", if the value is set to something like ".user.ini" - if that's
what you mean.

It may be, that you can change the setting later on, but it will have no
effect (f.e. if you change it using set_ini() ... if it doesn't trigger a
E_WARNING or something the like).

Hope this answers the remaining question. If not, I kindly ask you to write
some examples.

Bye,
Simon

Ok - here is what I see happening now.  PHPINFO shows a setting named 
'user_ini.filename' set to '.user.ini'  At the same time the setting 
"loaded configuration file" shows that a "php.ini" file was loaded from 
the current sub folder that this call to phpinfo was running in (as I 
expect!).  So apparently my host has set php to look for "user.ini" 
files, but "php.ini" files are still accepted and loaded.


I'm guessing that despite the user_ini filename setting, a PHP.ini file 
will still be read, which suits me just fine.


Thanks for all the help Simon!

Hi, Jim

I suggest to read this page of the tutorial. It seems, that it solves the
questions, you posted here:
http://www.php.net/manual/en/configuration.file.per-user.php

Please be aware, that the ini-file is not re-read on every request, but
after a defined time.
Neither are all settings changeable in those per-user ini-files.

Read also the other pages in this chapter, they're good to keep in mind ;)

If you're now calling the script from a webserver, you called by requesting
a page on a subdomain or a top-level-domain, doesn't matter.

I need more!
1 - the doc you mentioned refers to 'user.ini'.  Does that literally 
mean the file is called 'USER.ini'?  I have been placing my .ini 
overrides/settings in each of my folders under the name 'php.ini'.  Do I 
have to change them all because it seems that they are working fine.

My best guess is that either $props or $params contain a function reference or 
similar construct. Examine their contents with var_dump.

As a check you could expand out the effect of array_merge and see if you still 
get the same with a PHP implementation.

$url = 'http://google.com';


 $props = array

$url = $url . http_build_query($props, '', '/');


It may be possible that params has unsafe data in it.  The previous dev did
not validate the data passed in via get.

The code populating params looks like:

$params = array
(
'd' => $_GET['d'],
);

$job = Job::getInfo($params);

An easier way to do that would be using the diff() method of a DateTime object 
on another.

Good Point!  I never looked at it that way.  I guess the Date function 
can't be relied on in that case.  So now I'll have to calculate my time 
in a mathematical way instead of letting Date translate it for me.

Aziz, please try not to top post :)

It's true that the date() function takes in a timestamp as its argument,
but a timestamp is a number representing the number of seconds since
00:00:00 1st January 1970, so passing in a very small number of seconds
is perfectly valid.

The only thing that would account for the 7 hours difference is the time
zone, which would also be part of the timestamp.
http://en.wikipedia.org/wiki/Unix_time gives more details.

The resulting subtraction is not a valid timestamp, but rather the
difference between the two timestamps in seconds . The resulting diff can

Re: [PHP] date time problem

[Aziz Saleh]

Jim,

The date method takes in a timestamp (not seconds away).

You have the seconds, you will need to manually convert those seconds to
what you desire (minutes = seconds / 60), (hours = minutes / 60), etc..

I have this:

$diff = $exp_time - $curr_time;
// produce a display time of the diff

Currently the results are:

curr_time is 06:12:03
the diff is 2584
All of these are correct.

BUT time_left is 07:43:04 when it should be only "00:43:04".

Thanks for the quick response, but why do I want to show the time in GMT?  However, I did 
try it, changing the 'time_left' calc to use "gmdate".  Now instead of a 7 for 
hours I have a 12.

exp 07:34:52

That's the only approach I could think of.  I may have to tell the director it 
may be a bit slow but at least she won't have to do it by hand!

It also depends on the amount of kids, families and stays.

If the numbers are low, by hand may be a lot easier and faster

Sounds like a job for a directed graph data structure. I wish I had time to 
knock up a solution but I don't right now. This article should help you get

While definitely a tempting coding exercise, I just want to say that if this is 
urgent in any way, shuffling cards with the kids' names on them by hand might 
just be faster and less frustrating :)

OTOH, if this is something you're going to have to figure out week after week, 
then a software solution might be handy.

This is also not an *easy* problem to solve; there isn't a simple approach to 
optimizing this sort of thing because you're building a net between all the 
various kids based on past stays, in addition to the constraints of host family 
 capacity. Thus your previous code attempts might in fact be the end result.

Obviously, structuring the data is the key here.

I'm thinking of 3 primary models: Kids, Hosts, and Stays.

Kids and Hosts seem pretty obvious. Stays is the interesing model, and needs to 
have joining tables with Kids and Hosts.

A Stay will have one Host, and have many Kids and a date.

The algorithm then needs to make the graph where it can pull out the number of 
times any particular kid has stayed with another, looking something like this:

Amy:
   Ben: 10
   Jill: 3
   Carlos: 7
   Chen: 2
Ben:
   Amy: 10
   Jill: 5
   Carlos: 8
   Chen: 3
Jill:
   … and so on

Then you be able to pull through that graph and find the smallest number of 
stays for each kid.

Not simple, but I hope this helps.

Assuming you don't have to be exact, somthing similar to this might work.

Assign each kid to a host family randomly
for each kid, check how frequently it has been combined with the kids in
its assigned family.
if it is too close, swap with a different family
when all kids in that family are processed, move on to the next family and
repeat, excluding the first family for swapping. do the same for all
families excluding the previous families. when you have completed all
families, do another iteration or two of the whole process.

Oh, no, this is definitely not homework! :)  Although it certainly seems like a 
homework question.  This is a real world problem.  I'm keeping track of which 
kids stay with which host families in the database.  My initial approach was to 
start with kid 1 and see how many times the other kids have stayed with kid 1.  
The move on to kid 2, and so it.  This gives me a score for pairs of kids.  
However, if say three kids are staying at a host family, what is the best way

I would create a matrix of all kids crossed with every kid. Everytime a kid
is put in a home with another kid, ++ that index. When dispatching kids,

Hey Tim,

It seems that deleteObject takes in 2 params, and you are sending it 1
param. I would recommend you look at the documentation and make sure you
are sending the right params.

Hi Aziz,

 Thank you for getting back to me!

 I appreciate you spotting that error.

So I corrected that

deleteObject(array(
'Bucket' => $bucket_name ));*


 // The response comes back as a Simple XML Object
// In this case we just want to know if everything was okay.
// If not, report the message from the XML response.
 if ((int) $response->isOK()) {
echo 'Deleted Bucket';
echo '';
echo 'List Buckets';
  } else {
echo (string) $response->body->Message;
  }
 //echo '';
}
?>

  Delete S3 Bucket
   
Bucket Name:

I have to agree on the code bloat. Unless your requirements are

generally quite adequate.

Never thought about creating a PHP email client. Interesting idea...

Re: [PHP] delete S3 bucket with AWS PHP SDK

No Problem, the issue is that you referring to the invalid post element
$bucket_name as opposed to the correct on bucket_name.

*$bucket_name = $_POST['$bucket_name'];*

Should be

*$bucket_name = $_POST['bucket_name'];*

Re: [PHP] delete S3 bucket with AWS PHP SDK

[Tim Dunphy]

Hey guys,

 Sorry about that i should have posted the full code to give you some idea
of context. Anyway, here it is:

deleteObject(array(*
*'Bucket' => $bucket_name ));*


 // The response comes back as a Simple XML Object
// In this case we just want to know if everything was okay.
// If not, report the message from the XML response.
 if ((int) $response->isOK()) {
echo 'Deleted Bucket';
echo '';
echo 'List Buckets';
  } else {
echo (string) $response->body->Message;
  }
 //echo '';
}
?>

  Delete S3 Bucket
   
Bucket Name:
  *  *

  

So, as you can see I am taking the 'bucket_value' from $_POST and passing
it into the call to S3.

When the form comes up on the web I give it the name of one of my S3
buckets. The result is the following error:

Notice: Undefined index: $bucket_name in /var/www/awssdk/delete_bucket.php
on line 67 Warning: Missing argument 2 for AmazonS3::delete_object() in

I hope that clarifies my situation a bit. Sorry for not providing that

Re: [PHP] delete S3 bucket with AWS PHP SDK

[Aziz Saleh]

Hi Tim,

Is the call working? Does it actually get deleted?

This could just be an issue (which I see alot) where developers do not
check for variables or preset them before usage, causing those notices to
come up (pretty harmless most of the times).

Re: [PHP] Switch Statement

[mrfroasty]

Hello,

I suggest you put default in that switch statement and var_dump the
$_POST.That should be enough for a programmer to pin point what goes wrong.

P:S
**You might want to consider versioning your codes to go back into its
history to see what has changed.

Your code is failing because $bucket_name, I suspect, is null. Where do
you define this variable before you use it in this bit of code:

$result = $s3->deleteObject(array(
'Bucket' => $bucket_name ));

This is what you should have in place of all of the above:

session_start();
error_reporting(E_ALL | E_STRICT | E_NOTICE);	ini_set('display_errors', 
'1');

set_time_limit(2);// if you use more than 2 secs you have a problem

I don't have a link unfortunately. The system I did it for is proprietary. 
But I do recall it was a pretty switch in the JS to view the list from the

If you're looking to create a SQl table then most but not all browsers can 
use SQLite locally for data storage ( it does require newer browsers).


You haven't stated the goal for this so other options could include 
sending csv or json data down to the browser and using jquery, angular or 
some other JS framework to manipulate that data may also be an option




I had exactly this situation, large list with the autocomplete. I cached the 
list to a JS file and ran the autocomplete from that. It works well if the 
list is relatively static which mine was. It will be tougher if the list is 
dynamic, but you could send the data down after the initial page load.

use SQLite locally for data storage ( it does require newer browsers).


You haven't stated the goal for this so other options could include sending 
csv or json data down to the browser and using jquery, angular or some other 
JS framework to manipulate that data may also be an option

The question I have is why? Should your upload fail for any reason you've got a 
half processed file that is non-recoverable.  No do-overs. If you stick to the 
standard processes with out the extension,

Upload
Save somewhere (or leave in temp upload folder)
Process
Send result back to user 
Unlink file

Generating the file and sending it to the user is also pretty standard

Create your dataset
Send appropriate headers
Send data
Close connection

For this, there usually isn't a need to save the file. You may run into issues 
streaming the data to certain browsers. 

Also one of the main downsides to your upload is high load situations or large 
file situations (where file size exceeds php's upload limit). 

My personal preference is to save that file to disk so that if needed I can 
work with it later ( if say the server load is high) and email the results to 
the user.

Re: [PHP] PHP and curl

[Shawn McKenzie]

Unfortunately this isn't anything to do with PHP.  I don't have any info on
the app, what it's supposed to return or what the parameter passed should
be.  The PHP soap call is working, but the app isn't returning what you
want or expect I guess.

The problem was to do with an image upload, so no, not useless.

In an earlier email I detailed some methods for validating other types, such as 
DomDocument for HTML, XML, svg, etc, or fpdf for PDF. 

And on behalf images: GD you are using handles only

At the moment those are the 3 raster formats you can use on the web, so those 
are the ones that pose an issue. If you're using anything else, it's not for 
web and doesn't need to be in a publicly accessible location.

The extension comes from the user. Never trust the user, ever.

My script does effectively strip out malicious code though, even if it can't

GD isn't a PHP parser, and PHP doesn't execute the image before GD touches it. 
Infact, Apache isn't even involved between GD and the image at that point, so 
it won't suffer from this bad config.

What you are doing is dangerous, because you force the

Erm, no, the image isn't being executed.

If you think it's fine that a user be able to upload malware, then you're going 
to have a very bad time.

But we MUST exclude, it is executed on the web server.

This is important too, but in this profession belt and braces is best I 
believe.

Sorry for this late post but I'm amazed nobody consulted the doco.

The php.net site has a whole section titled "Handling File Uploads".
Also check out finfo_open and finfo_file.
If your are a windoze user you need a dll.
If you want Apache to handle PUT requests you MUST tell it to run a script as 
it cannot write to web root.

Yes, @method and @property are very handy. Out of curiosity, since you're
providing magic getters and setters, why not use __get and __set instead of
__call with matching on "get_xxx" and "set_xxx"? This would allow using the
simpler (and IMHO much more expressive and PHP-ish) forms

$obj->foo = $obj->bar + 5;

Sounds like it may have been moved from a Plesk server to a
non-Plesk server (or something using a similar path setup).  If it's
still Apache-based, yes, an .htaccess mod_rewrite directive should
suffice.  And, while it's out-of-scope for this list, an example, for
posterity:

# .htaccess - placed in the web root
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [QSA,R,L]

I'm saying the site should be served entirely under HTTPS. There shouldn't be 
separate https/http directories. Apache (or whatever your web server is) has a 
certificate installed on it and that vhost is configured to only respond to 
https requests. Typically this also means running a separate vhost on http that 
redirects to the https variant.

Where is this new host? It should be a dedicated box (vps or other) due to how 
the certificates need to be issued (dedicated ip address).

Best,

–Josh

I understand that cc processing should be done via https.

Normally, that means to me that I place my $ scripts in a https directory -- 
the problem is that I don't have one with this host.

So, I am asking how does one do that with a https directory?

Did you setup the server (Apache / nginx) configuration? The entire site should 
be served under https if you're doing CC processing

Re: [PHP] php fopen https error

[Shawn McKenzie]

I thought I covered that.  The bug was fixed 7 years ago.  Upgrade PHP, I
doubt there is a patch.  I understand that not all coders or distributions
will have the latest version of PHP, but come on, how many thousands of
bugs have been fixed in 7 years?  You're going to run into more.
 Alternatively you could try and suppress it.  From the bug it sounded like
it was only the warning that was the bug, so the code should work.  I can't
test because my PHP on CentOS is only 3 years old (5.3.3).

 $contents = @stream_get_contents($handle);

Please understand that some Distributions do the "only backport security

I do not complain, I just try to understand the issue.

I am not sure how what I am supposed to do with this information.

#39039 says it is a bug and it was fixed.
How do I proceed to understand this bug?

I believe this was a bug, is only a warning that may be suppressed and may

SOAP functions can be called as methods of the SoapClient object.  Maybe:

Ok, imagine this scenario. A user uploads a .tif. this isn't a web format, so 
we treat it as a binary file, uploading to a non web accessible area of the 
site. Tell me again where the exploit is please.

Why that???!!! Why should users only upload files, that are used "for web", and
what does this mean, "for web"? Users may store personal files on your host,
because they use your website as a "cloud", as it is said today. Not "for web",
but for personal use on everey computer connected to the internet! That is
absolutly legitime and the ONLY reason to offer file uploading I can imagine! I
allow it only for authenticated, subscribed users. 

Nevertheless those trusted users may upload (unintenionally!) infected files.
And again: No virus was ever written "for web", but to harm computersystems,
clients and servers. They are just distributed via web.
 
Whould be great we could block them, and I appreciate your efforts to do this.
But sorry, your script shows me, that this cannot be done this way! Perhaps, if
you are right and GD processing really is harmless (I'm in doubt), we have a
clean jpeg (or gif or png). And then? What's about the rest?

Keep in mind, that PHP is a scripting framework to create websites, certainly
not a tool for virus detection! And we have a big problem with the Apache web
server, not because Apache serves possibly infected files, but because all kind
of files are NOT served, but passed to the script interpreter! That's awfull
enough, and opens a new exploit!

The problem was to do with an image upload, so no, not useless.

In an earlier email I detailed some methods for validating other types, such as 
DomDocument for HTML, XML, svg, etc, or fpdf for PDF. 

And on behalf images: GD you are using handles only

At the moment those are the 3 raster formats you can use on the web, so those 
are the ones that pose an issue. If you're using anything else, it's not for 
web and doesn't need to be in a publicly accessible location.

The extension comes from the user. Never trust the user, ever.

My script does effectively strip out malicious code though, even if it can't

GD isn't a PHP parser, and PHP doesn't execute the image before GD touches it. 
Infact, Apache isn't even involved between GD and the image at that point, so 
it won't suffer from this bad config.

What you are doing is dangerous, because you force the

Erm, no, the image isn't being executed.

If you think it's fine that a user be able to upload malware, then you're going 
to have a very bad time.

But we MUST exclude, it is executed on the web server.

This is important too, but in this profession belt and braces is best I 
believe.

Dear Ashley, nice, but useless for this problem!

First, because users may upload other things than images! PDF's, audio
files, videos etc! And on behalf images: GD you are using handles only
jpeg, gif and png. There are about hunderd other image types on the way,
users can upload! How to detect them, if the extension is missleading?

And even if we succeed: As your script demonstrates very well, malicious
code does not affect the rendering of the image. The hacker says: Hi,
this is a nice picture, play it, and then, please do this--follows his
code, that can be a desaster for the whole system.

Yes, your script seems to purge the image file, simply because GD does
not copy the malware code. But why are you sure about that? You cannot
see that code, OK, but may be it was executed in the plain GD
environement? What you are doing is dangerous, because you force the
execution of things that should be never executed!

"no no no" forget it. After all we cannot exclude that users come in
with malware. But we MUST exclude, it is executed on the web server.
That is the Apache chainsaw massacre as Steward whould say. And probably
it can be avoided by purging the filenames (not the files!). 

Nevertheless, the standard configuration of the Apache servers is
basically unacceptable. It must execute user requests and never ever
user files! Period.

Have nice days,

This is somewhat daft. Yes, Apache offers this feature, but you don't need
to configure it to work will all extensions. I'd be curious to know what
their issue is with using FilesMatch, since that provides a way to disable
this behaviour. And, honestly, who would have a PHP file per language? I
think it's perfectly reasonable to not allow that, because duplicating PHP
code across many files is an incredible stupid way to support multiple
languages.

"Some people run all their files through PHP" - true, but that doesn't mean
they should, or that you, as a responsible web host, should be endorsing it.

PHP developers should absolutely validate all content coming in from users
in every possible way, but I would be highly dubious about trusting a host
who gives the reason above for what I consider a lax and insecure Apache
configuration. It's like saying they sliced your arm off with their chainsaw
because it's made for cutting things, attempting to dodge all responsibility
for having swung it in your direction!

-Stuart

It seems this is the standard apache configuration, but that's no excuse. 
Googling returned many results where this was described as a major security
threat
e.g. "Beware of the default Apache 2 config for PHP"
http://ilia.ws/archives/226-Beware-of-the-default-Apache-2-config-for-PHP.ht
ml
On that site the solution was to change AddHandler to AddType. 
My service provider is going the FilesMatch route.

That's like radio Eriwan: In principle you are right!

BUT: I want not show the whole MIME-structure in the mailbox overview!
That whould be absurd, and indeed could only be done by reading the
body.

Nevertheless we have in the primary header of any MIME compliant message
the line "Content-Type". (We have it also in the headers of the attached
parts, but that is not intresting now)

In this primary header (fetched by "imap_fetchbody($mailbox, $msg_no,
0)) the leading part of the MIME-type description can have only two
values: "text" or "multipart". Right? I'm sure you will never find other
values in the _primary_ header.

That's the first decision for your script. "text: no attachment",
"multipart: attachment". No matter the subtype-value after the slash,
you have what I want! And ONLY by looking on the header. And this ist
100% valid, because it follows logically from the imap- and MIME-rfc's.

About malformed messages violating the protocols we discuss next year,
you agree? :-)

You may evaluate the subtype after the slash. If the type is multipart,
you will find "mixed", "alternative", "related" or "digest", if the type
is "text", you will have "plain" or "html" as subtype.

May be there are more subtypes on the way, but all these are optional
for the primary job, a decent mailbox overview must do: tell the user,
whether there are attachments or not.

My own webmail client does this job pretty good, but it violates my own
standard of good practice. Whether "imap_fetch-overview()" nor
"imap_headerinfo" are reading the "Content-Type"-line while parsing much
other header lines of minor importance. My script must refetch the
mailheaders to do that! This is an ugly overhead I wish to avoid.

BTW: the "squirrelmail"-staff, leading in the PHP-webmail-world, just
ignores the whole imap-extension of PHP. Instead, they talk low level
with the server. But this way is a little bit too hard for me...

Therefore my pledge to all involved into the development of the fabulous
PHP framework, section imap:
Please ad the primary MIME-type to the objects returned by
fetch_overview and headerinfo! It's so ridiculous simple: read the
"Content-Type"-line in the primary mailheader as I must do afterwards,
only because you do not!

Sorry for my bad english! 
What I want is, that the users of my webmail client can see at a glance,
if mails in their mailboxes have attachments or not. (Thats a human
right! But of course I was joking... It's simply nice to provide this
information and should be done)

Yes, I could do even that! But this is worse! Imagine, you do this in
the overview of the mailbox content! This can be hunderds of mails! My
script paginates this stuff in blocks of 16 (or something) mail headers,
but even then you have an huge overhead.

Why? 
Because, first you must collect the sender and subject information. This
is done by "imap_fetch_overview()", parsing the mailheaders and grabing
some server data, like arrival date, size and flags.

Fine, but you still know nothing about attachments! You must do
something more. OK?

You whould run "imap_fetchstructure()", but sorry, that's the wrong time
and place. You will need this monster object only when the user _reads_
some specific mail. At the moment, we are not reading, but collecting
mails to present them in the mailbox overview.

My script modestly fetches the mailheaders again to read the
"Content-Type"-line. That's quite fast, works fine, but is stupid,
because this headers were fetched and parsed just before! 

I ask you, and all PHP developpers: Why the hell this function does not
parse this line too? (a part of so much others of less importance) The
same is true for "imap_headerinfo()". And: of course this
"Content-Type"-line provides by far not the complete MIME-structure as
"imap_fetchstructure()" does, but, as said, we don't need this at the
moment.

The result is a script, that I self whould not describe as "good
practice" because of it's duplicated parsing of the same string, but I
found no other way yet.

That's my problem, you see?

Sincerely
Niklaus

One I have used, and continue to use in Apache environments, is place uploads 
only in a place where they cannot be executed by turning off such options and 
handlers in that directory. This is *in addition* to untainting files and names 
of uploaded files.
