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.

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.

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 ));

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

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.

No, no, no! That is not a good stand-in for fundamental security
principles!

This is a better method for ensuring an image is really an image:







Obviously it's only rough, and checks only for jpeg images, but that's
easy to alter. I've just tested this with a regular jpeg, the same jpeg
with PHP code concatenated onto the end (which still appears to be a
valid image to viewing/editing software) and a pure PHP file with a .jpg
extension. In the case of the first 2, a new jpeg is generated with the
same image and without the code. The third example just echoes out an
error.

Yes it is possible but a) not at server side because JavaScript is run on the 
browser, and b) this is a PHP list not a JavaScript list.

Saying that, why aren't you populating it on the server side with PHP?

I think most importantly, validate your input!

If you're expecting an image, check to make sure it's an image. Use the
imagecopyresampled() function that's part of GD to create a duplicate of
the exact same size to ensure that it's both an image and not containing
a hidden payload (which has happened to JPEG images before)

If it's a file of another type, use a different appropriate method to
validate that. DOMDocument will deal with XML and HTML documents, you
can use zip functions to inspect Office documents (the newer types at
least), FPDF to handle PDF files, etc.

By only checking the extension you're relying on user-supplied data,
which by definition is tainted.

776 won't matter in the case of a directory, as the last bit is for the
eXecute permissions, which aren't applicable to a directory. What 

It's possible that this is an SELinux issue, which adds an extra layer
of permissions over files. To see what those permissions are, use the -Z
flag for ls. Also, check the SELinux logs (assuming that it's running
and it is causing a problem) to see if it brings up anything. It's
typically found on RedHat-based distros.

I'd argue that a large proportion of really secure servers out there
won't respond to a lot of what Zmap pings out. Nmap works by throwing
out requests on a bunch of different ports, not just ping, which is
slow, so I'd be surprised if Zmap could really rival that while giving
the same results. Bearing in mind there are over 4,000 million (I won't
say billion, because that's a million million, despite what the
Americans say!) IPv4 address out there, 40 minutes is a ridiculous
amount of time to even scan half of that, especially given the fact that
IPv6 is being majorly pushed because IPv4 is apparently running out of
free address space! Then not forgetting that lots of websites exist on
the same IP address/range, I would say the article is lacking on so many
details as to be untrue.

Could it be that the mysql service on the server has stopped. Typically you'd 
do something like this on RedHat/Fedora servers:

service mysqld status

That would certainly stop the extension working from within PHP.

$GLOBALS['hello'] is essentially a synonym for $hello in this context.
$GLOBALS is just an array of all variables that have global scope, so
adding to this causes variables to be added at the global scope level.
But, like I've said a few times, this might not be your specific
problem, and without seeing the actual code that causes this problem,
it's very difficult for anyone to help. Your code examples don't exhibit
the issue you describe, so they're not useful in the context of
pin-pointing the problem. If you can post code that *does* give that
problem, then someone on the list may be able to help.

Actually, as we've explained, your example does _not_ show this, it works as

doing this

Is your class maybe inheriting from another one and that contains the code

The $GLOBALS array is what's known as a super global. Elements within the array 
are reflected as global variables and vice-versa.

Not sure what you mean, but this super global works both ways. Don't 
necessarily get hung up on this being the exact code, it's just a proof of 
concept of how it /might/ be happening. Like I said, there are probably other 
ways too.

As you've said that your excerpt doesn't replicate the problem, it's not
that useful really to accurately illustrate it. I would say for definite
that it's some of the surrounding code, probably something similar to
this:

class Hello
{
private $_world = 'World';
function __construct(){}

function test()
{
$GLOBALS[strtolower(get_class($this))] = $this;
}
}

$clsHello = new Hello();
$clsHello->test();

echo 'The variable $hello is
'.gettype($hello)."\n".print_r($hello,true);


There are probably many ways to achieve this, I can't think of a sane
reason for any of them though!

I cannot replicate this. That code you supplied correctly gives a notice
warning about an undefined variable '$hello'. Are you sure that that
simple code excerpt is giving you the problem you describe and there's
not more to the whole thing, more code, etc?

I'm not saying the method is bad, but the way Facebook does it isn't great, I'm 
constantly seeing people online who "sign out" when I open up a message box. 
Now that might be genuine, but I'm not *that* unpopular!

Ah, so you don't need to see the details of the sessions then. Facebook does 
this (badly) by using javascript on the client side which triggers an update of 
a timestamp on the server, which then allows you to determine who is online (or 
was within a given time limit)

Apparently it has problems when browsing in "porn" mode, and mobile
safari has major problems with it. I'm basing this on previous posts on
forums I've been on, so it might have been fixed now, but I don't know
for sure either way.

Like Matijn said, unless you're using some kind of client-side method to
continually poll the server, you can't know if they've just closed their
browser. There are Javascript events for exiting a page, but they don't
work correctly on Safari and iOS Safari.

You don't have to actually save anything to the DB manually, just
instruct PHP to use the DB for its own sessions, rather than files.

Do you really need to inspect each visitors session in detail, or do you
just need a way to determine how many unique visitors are on the site at
any one time?

I don't think there's anything inherently wrong with writing your own
form processing code, as long as you understand what's going on. Many
frameworks do make this a lot easier though, but sometimes I find it
encourages you to ignore some of the details (like security) because you
"know" the framework handles that stuff.

I would say code forms on your own first, as a learning experience, then
use frameworks once you know what you're doing.

You say tools, but would he consider a full-blown complex CMS as merely
a tool, or not? At this point, I agree, your best option is probably a
CMS with plugins, because 20 days is not much time to build that sort of
thing, and that's coming from someone who develops in PHP for a living.

20 days seems awfully ambitious, does your professor expect you to code
these by hand or are you allowed to use an existing CMS, I ask because
your original question seemed a bit odd.

For e-commerce you're better off choosing a CMS which does that out of
the box. Joomla has plugins that allow you to do these things, but it
can be a hefty CMS, and it's not particularly suited for shops, plus it
has a bit of a learning curve and some large security holes (which I
know first hand having had to just get a Joomla site to pass a rigorous
security test)

Lastly, please try not to top post :)

Erm, Joomla is a CMS, which means that you don't have source code for
individual pages like that. If you want, you don't have to get involved
with the PHP at all in Joomla. What is it that you're actually trying to
achieve?

Quoting the data is not the same thing as validating it.

I think that's a pattern that people use to distinguish their tables from 
views, etc, but personally I find it a little pointless. It doesn't really help 
in any way, and just means more typing.

Using a prefix for a set of tables in one db where you might have several 
things using the db (i.e. some hosting limits the databases you can have) makes 
sense, and especially so if you name it sensibly as in your first example.

Re: [PHP] browser rendering

Width and height parameters on an image aren't required in HTML, it's preferred

   To have pecl, you need to install PEAR first, "yum install

 (or "yum install php5-pear") should work.


   Then you can try "pecl install pdo_odbc."

If you're looking for a specific package, try

yum list php*

The * acts as a wildcard, it makes it easier to find packages whose names 
change slightly. Should avoid the ambiguity of the various lines of advice

I think that requires external libraries that are not part of a typical shared 
hosting installation, which is what it sounds like the OP has. 

I've used it before myself though , and aside from some oddities, works very 
well.

Have a look at fpdf, its a class that doesn't need any special server-side 
support. Its basic, but is pretty good.

It wont, the fragment is always local. You'd need javascript to handle that

They probably aren't using a paid for list but getting a list of contact
forms from a web search. I still maintain that asking some sort of
question that only a human could answer is best, and that doesn't mean a
tradition captcha like ReCaptcha. That's proved easier for bots to fill
than humans now!

This is really starting to sound like some sort of weird bug somewhere.
I know this is the typical IT response, but have you tried restarting
Apache? Also, this shouldn't happen, but try restarting your browser
too. Maybe it's exhibiting some strange cache bug.

I've noticed the first line looks a little odd. It might be valid, just
probably not the way I've ever done it. For my own sanity, could you try
changing it to:

if (isset($_POST['lastname']) && isset($_POST['lastname']))

Have you used the network inspector of your browser to see if what you
think is being sent is really being sent? Firefox and Chrome come with
these tools built in now.

Captchas are not very accessible. Not only do you often need a near
super-human ability to identify the scrawl that's displayed, but if you
can't actually see very well to start with (maybe your vision isn't
perfect or you can't see at all) then you have to fall back to the audio
replacement offered by the captcha. I've tried listening to some, and
they are awful.

One type I've seen (and use myself) which is gaining traction is that of
asking for a human type of response to a question, or have them perform
a simple mathematical problem, where the numbers are replaced with
something else.

There are simple web servers you can run on Android, and also standalone PHP 
parsers too (i'm using one myself - search the play store for php server). Is 
that the sort of thing you wanted?

It sounds like some kind of memory problem. Can you run a memory tester on that 
server to see if that's the cause?

Ah, I see. I think that's not an issue as such with regular expressions
having problems, more that bit limitations has a problem with numbers!
Bearing that in mind, this does the trick:

$string1 = '9';
$string2 = '99';
$string3 = '99';

var_dump($string === (intval($string1).''));
var_dump($string === (intval($string2).''));
var_dump($string === (intval($string3).''));

I'm getting the expected results on my machine (32-bit) but a 64-bit
machine would get the correct results for larger numbers.

Do they? Regex's deal with strings, so I don't see why they should have
such issues. I've certainly never come across that problem, or heard of
it before.

The op wasn't about casting a string to an int but detecting if a string was 
just a string representation of an int. Hence using a regex to determine that. 
Regular expressions are not just about giving feedback to the user.

Not really.

You script is web accessible right? It just opens a file and delivers it
to the browser of your visitor. It's easy to make a script that pretends
to be a browser and make the same request of your script to grab the
file.

For Linux I quite like KATE, it's part of the KDE stuff. Netbeans is
great as a full-blown IDE, or Geany is quite nice if you need something
in-between those two. The great thing is that they are all available on
Windows too.

The thing is, is_numeric() will not check if a string is a valid int,
but any valid number, including a float.

For something like this, wouldn't a regex be better?

if(preg_match('/^\-?\d+$/', $string))
echo int

At this point I don't think he's looking for an actual solution, but
merely wants to moan about open source. OSS has flaws, of course, but
even someone so narrow minded would have a hard time arguing in earnest
that it suffered from too little choice and a lack of solutions to a
problem.

What about this:

if ( !( ($current_page == $saved_page) and ($current_ip == $saved_ip)
and ($current_dt < ($saved_dt + 3600)) ) )

The 3 sub-expressions are grouped with an extra set of brackets and
the ! inverts the whole thing, so no need for an else clause.

Well, you don't really help yourself with a reply like that to the very people 
helping you.

I and others have pointed you towards open source solutions, the fact you don't 
want to put any effort in to make them work for you is not because of the state 
of open source software.

Your behaviour though makes me less-inclined to offer help in the future.

I believe Cake has this, although you need to have your fields named in
a certain way so that it understands the relationships, not sure if it
automatically recognises foreign keys as it was developed back when
MyISAM was the typical storage engine for MySQL, and that didn't have
foreign keys.

I think there are also CMS-like plugins for other slimmer frameworks
like CodeIgniter which have this functionality, but again, I would
assume previous rules apply with regards to your field naming
convention.

In any case, you could probably take something you like from another
framework if you have the time/inclination/capability.

Not just that, but if you set a cookie, you won't be able to retrieve it
in the same script I believe. It's only available in the $_COOKIES array
once you refresh the page, as that's when the super global is populated
from the cookie data that the browser sends.

I don't know if that would hold true for forms that contain multiple
submit buttons.

There are plenty of good reasons though for multiple submit buttons in a
form, such as a shopping cart where each button is tied to a product and
allows it to be removed.

You can manually write a cookie on your machine, or use a special script
that only you visit that contains a setcookie() call (it only need be
set once). From there on, you can check the $_COOKIES super global for
the presence of your cookie. To test, visit the site with a different
browser (browsers won't share the cookies) and you'll see the visit
logged.

You could do it by checking for your ip address if you have a fixed one, or set 
a cookie with a long life and check for that, discounting visits when either 
are true

Also, with the example:




There is no hidden attribute for input elements, and no form attribute
either. If there's a need to stuff elements with extra attributes then
it's best to use data- attributes.

Use a different value or name on the  button. Don't use 
JavaScript to trigger the form like that. Its not necessary and will bite you

Aside from all the warnings and potential logic bombs?

You will have a negligible performance hit with all the isset() checks you'll 
be using, but they won't be noticeable, and its preferred to use them than not 
to avoid issues with missing values.

I'll take a bet that the Apache server is running as a different user
from your login, and doesn't have permissions to open sockets. You could
either give the Apache user permissions, or put the exec call as part of
an argument of sudo.

At no point was I slamming someone for using the old functions, in-fact
I was trying to make a joke of that and point out that the msqli
functions would be better, unless you really do believe that kittens
will kill programmers...

The thing is most of us expect the person asking the question here to
have done at least a little bit of research into the problem, even if
that only extends to "I'll Google some of these keywords in the error".
That should at least have produced the same advice about those old
deprecated functions, but I wanted to reiterate it a bit just to be
sure. It can't hurt to know something like that.

The fact is, what you considered a simple answer was bad advice, and
would have just taught more people that those old functions are fine,
when in-fact they are not. I think it's very important to make people
aware of security concerns, especially if they're a beginner with the
language.

Sorry, just re-read the OP and realised he was using the mysql_*
functions.

I still stand by my statement of not using them though. People should be
advised that the functions are deprecated fully now and are not safe to
use.

Actually, the question never mentioned mysql_* functions, so telling someone to

Personally, I favour CodeIgniter as a framework to handle stuff like
routes and stuff. I do the templates like this:


 1. Call up the template.php view and pass across name of content
view to use for the page/section and other page-specific bits
 2. Template view pulls in header view and populates it with default
 stuff, which can be overridden with stuff from step 1
 3. Template view pulls in the main content view which deals with
that page
 4. Template view pulls in footer view and populates it in the same
way as header

This is the most basic example, but often the template view will deal
with other bits like navigation bars, sidebars, and other shared
sections. You need not limit yourself to one template view either, you
could have several depending on the section of the site.

What I would start to do is break out common parts of pages to include files. 
This would be stuff like headers, footers, sidebars, etc.

At worst, you could update the page2 templating engine to account for your new 
elements. But like I said, I think the very style page2 uses is extremely 
limiting, and will make maintenance later on.

I've just had a quick look at page2, and I can't say I see the point.
You'd end up having to write a lot more code that was harder to manage
by adding each element through a class like that if your site got even
moderately complicated.

There are many templating engines, and some are more complicated than
others, don't write them off just yet. Technically speaking, page2 is a
template engine of a kind, so you're already using one.

You could use an existing templating solution, like Smarty, although for
what you want to do it might be overkill. A few str_replace() calls
shouldn't produce too much overhead, but it depends on the size of the
text string in question. If it's just a couple of paragraphs of text, no
problem, something closer to a whole chapter of a book will obviously be
more expensive.

You could try eval() on the block of text, but if you do, be really
careful about what text you're using. I wouldn't recommend this if
you're using any text supplied by a user. As a last option, you could
have the text stored as separate parts which you join together in one
string later. This might be less expensive in terms of processing power
required, but it also makes maintenance more of a hassle later.

I would apply the discounts where they made sense from a customer POV. Would 
you expect a t-shirt discount to be applied to only the base item or the 
product as a whole? I'd say tge whole thing. You could have various areas in 
your code that apply discounts at different levels: per item, per group of 
items (bogof, etc), and per basket.

I believe Chrome supports drag and drop for file inputs now. I do know

As well as rtf, the OpenDoc format is easy to read from PHP. Essentially
it's just a bunch of XML files zipped up. Images are kept in the archive
too, which is a handy way to retrieve thumbnails of docs also!

I would say this is the username/password being used precisely for
authentication, otherwise you wouldn't need to pass them across to
exec()

You can use the session, but the only way your script will know what
session to use is if the clients are sending the session id as part of
their request.

It looks like you're trying to re-invent authorisation procedures.
Typically, the first request logs a client in and retrieves a hashed
key, which is then used in all subsequent requests so that the server
can correctly verify the client. You can do this the way you suggested
with the session, but you must ensure that the session id is passed
across to your script by each of the connecting clients. That will be
done either as part of the head request, or as an extra parameter in the
URL.

It shouldn't be too hard to code that. Most examples I've seen pull in
the first 1 or few records to aid the user as an example. Then they're
given a list of the possible fields to match against one by one.

I'd just try and avoid the hyphens in the variable names in the first
place if you can. Can you guarantee that everyone working on this system
will know when to encapsulate the variables in braces?

It does sound like it's definitely a problem their end. Could you alter
the script in some way to check for a token set on the correct schedule?
Or, perhaps rename the script and set up the cron to it again, so that
if there is a secondary link to it in cron it will fail, and might give
you an idea about where it's being called from.

I know this is all a crazy attempt to prove it's a problem with the
hosting, but from experience they can sometimes be slow to recognise it
without a lot of definite proof.

Have you tried removing the job entirely from cron and re-adding it? It

Crontab is the daemon which runs cron jobs, and some distros have set up
special files called cron.daily (or daily.cron I don't recall),
cron.hourly, etc to make it easier to schedule jobs.

As you're entering this through a control panel (presumably a web-based
one?) I would guess that's not the problem. It could be that the
hostings control panel software has had a hiccup?

Are they definitely only in the cron list once? Could someone have tried
to "help" by adding the job into the daily.cron, but forgotten to remove

It's a bit odd that you're parsing all .html files as if they were PHP
(little bit of a waste, and does mean you'll have an extra step when
configuring a server to run the code)

That aside, I don't see 23 lines of code in your example, so I'm
assuming you've snipped a lot of the beginning (you've not mentioned in
particular which line in your excerpt is the 23rd). What's in your
db.php include? Are there any checks on whether a connection has been
established or not there?

 Geo IP is based on IP, and I must warn you that IP data is not
 always
 accurate. Especially here in Europe, companies that are based in
 multiple countries sometimes only register their IPs in a single
 country, and share them between all the countries they are active
 in.
 This will give you wrong data from GeoIP. The time difference will
 only be 1 hour at max, but still.
