It's really frustrating Look in your php.ini and make sure log_errors is on and the filename it's directed at is writable by IIS. Restart IIS and PHP errors should then appear in that file.

No need to pass AdminID in the URL at all. Store that ID in the

there on every subsequent page.

How do I do thatI see where...but not getting how:
If (mysql_num_rows($result) > 0) {
$_SESSION['AdminLogin'] = "AdminID"; //<thats where is
said "ok" before
header ("Location: Main.php?AdminID=". $row->AdminID); <
not sure what to do here?
} else {

Nope.
If (mysql_num_rows($result) > 0) {
$_SESSION['AdminLogin'] = $row->AdminID;
header ("Location: Main.php");
} else {
$msg = "Invalid Login";
}
But you then need to edit Main.php to change where it gets the
AdminID value from. Chances are it's coming from $_GET['AdminID'],
and simply needs changing to $_SESSION['AdminLogin'], but you need
to make sure session_start() has been called before you try to use it.
Worth noting that securing PHP scripts is not something that should
be approached lightly. If you really don't know what you're doing
you could make it even less secure than it already is, or at the
very least break it so it no longer does what it's supposed to.
Posting snippets of code for us to "fix" as and when you have
problems is not the way to do it and is fairly likely to lead to
more serious problems in the long run. If you need a PHP

I found this ( at a url that didnt let me send this msg... ) and I would know how to do it, but I believe there might be a cleaner, more elegant way to do it. In Java, you just need to implement the interface Comparable and provide a method called compareTo (as far as i remember) and then you can use one of the many sorting algorithms generically on objects that are comparable... Anyway, I didn't find something like that for PHP. Since I'm using symfony, I had a bit of a play with the objects at hand and simply did a sort($arrayOfObjects) and it did sort them by the id. Just wondering where it got the information on what to sort on (not quite) correctly for my case? I'm confused. The function you need is the one you mention in the subject. All you need to do is create a function that compares two of the objects, in whatever way you need it to, and returns -1, 0 or 1. The pass that to the usort function - it doesn't care what type of thing is in the array.

glob()
http://www.php.net/glob
How portable is glob?
How fast is glob? Being that it searches through the entire
filesystem, this could potentially take a long time (like if i have
wildcards early in the filepath pattern and lots of matches)
correct? If my file variations (wildcards) are just at the end of
of the filepaths and i don't have more than 1000 files in the
directory then will I most likely be 'alright' with glob (in terms
of time)? I have probably spent more time now 'considering' the
time implications of glob, than glob actually would consume when
operating...
Thanks for the quick response/solutions.
dK
Glob works on all platforms.
Glob does suffer from performance issues above a certain number of
files, and this can be system dependant. If you're unsure how many
files it may return you'd be better using opendir/readdir.
Not sure where you got the idea that glob searches the entire file
system, but it's limited to either the current working directory or
the directory you specify. So if your PHP file is in /var/www/htdocs
and you do glob('*.txt') you'll get all .txt files in /var/www/htdocs.
And if you do glob('/tmp/*.txt') you'll get all .txt files in /tmp.

I don't understand why you don't generate the thumbnails to have *exactly* the same filename as the actual image.

Best advice is to test everything thoroughly. I'll probably get lynched for saying this, but you could avoid most compatibility issues by using a table to put the images together instead of divs. Also what does the KISS principle mentioned below stands for please?

You can either store images for rooms with 1, 2, 3, 4, ..., n beds and overlay markers to indicate occupied beds, or you could composite the whole thing. 2) Slice images up such that you can build a room using positioned divs. This would be a lot easier but you'd be limited in what type of textures and looks you can give the rooms.

Firstly there is no need to serialise anything going into the session. Secondly I assume you want to store objects not classes. Thirdly there is no reason why it should not work, but there are some caveats you need to be aware of... * The class definition must have been loaded before session_start() is called, otherwise you'll end up with an object of type stdClass rather than your class. * Resources stored inside the object must be cleaned up in __sleep() and can be recreated in __wake() as they will not be stored in the session along with the rest of the object.

Re: [PHP] fread() behaviour
On 20 Nov 2008, at 01:29, Rene Fournier wrote:
I'm trying to understand something about fread(). I'm using fread()
on an incoming socket stream that will send, for example, 26630
characters:
while ( ($buf=fread($read[$i], 8192)) != '' ) {
$sock_data .= $buf;
usleep(1000);

As soon as the socket client sends the data, immediately the server
will echo:
Then wait nearly a minute, and echo:

So my question is, why does fread wait if there is nothing more to
read? Shouldn't it return immediately? (That's what I want.) And as
for the delay, it's there so that if the incoming data is a little
slow, it has time to catch up with fread. Thanks.
As Craige already mentioned, fread will read bytes until it meets an
EOF so unless the other side sends one or closes the socket fread will
wait for the number of characters you've asked for (8192) or a timeout
(which is the delay you're seeing). In other words it's not detecting
the end of the data, it's just timing out waiting for more.
You ideally want to have the other side tell you how many bytes it's
going to send. If you can't do that then hopefully the data you're
receiving has some sort of structure so you can check the incoming
data for some terminating string. If not then you've got a problem
that can't be reliably solved. You could mess around with the timeout
and/or make use of functions like socket_select to check for waiting
data, but what you'll end up with will be problematic on slow
connections and generally unreliable.

Well, if you didn't, and it's NOT an array, and therefore will NOT

has someone already use such syntax ? i mean as the first one.
The while would work if you removed elements of $my_array inside the

empty.
I would guess that your lecturers point is that you shouldn't call
count on every iteration as it's a waste of time. He may also be
confusing while for foreach in which case I'd leave because you're
unlikely to learn anything from him.

It's been a while since I've done Windows development, but IIRC PHP will only be able to tell that the DLL could not be loaded, I don't believe Windows exposes exactly what the problem was. It could probably be done by examining the external symbols on the DLL and manually checking for the presence of those DLLs in the path, but that seems like overkill. While the accuracy of this error message is not great there's enough info out there for it to be a short-lived issue for most people making the effort required to improve it better spent on other problems. -Stut -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The session was one of the greatest things that PHP has given to the web programming world. It should not be feared. Also, why clutter up someone's machine with stuff held in a cookie? 1. PHP certainly did not give sessions to the "web programming world". 2. Why clutter up your server architecture with sessions unless you're already using them reasonable purposes. What we're talking about here is a list of numbers, which I'm perhaps incorrectly assuming will be fairly short and extremely temporary?

First of all, don't top post, please.
Secondly, that won't do what the OP asked for. array_count_values
returns an array which tells you how often each VALUE was found in
that array. so: array_count_values(array(1,2,3,4,5)) will return:
array(1=>1,2=>1,3=>1,4=>1,5=>1). While what the OP wanted was:
some_function(array(1,2,3,4,5)) to return 5 (as in the amount of
values, not how often each value was found in the array).
count() would do it directly, and the other suggestions people gave
do it indirectly, assuming that the values between '|' are never > 1
char wide.
I think you'll find Kyle was suggesting that the OP use that function
to count the |'s in the string. Add 1 to that and you have the number
of elements explode will produce. More efficient if you're simply
exploding it to count the elements, but count would be better if you
need to explode them too.

If you're going to use regular expressions you need to read the manual

require FS_CONTROLLER.'/'.strtolower($class).'.inc.php';

That event should still fire regardless of whether it's a window, tab or iframe. It refers to the page closing, not the window. However, any event that fires when the user leaves a page (either by clicking on a link or closing the window) is likely to be prevented by popup blockers, so you can't rely on it working at all. A sensible session timeout is the only real solution to this "issue", possibly aided by a periodic keepalive request. -Stut -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

There was no mention of chr(10).
Outputting data in CSV format is not hard. Simply echo the header row
if necessary, followed by "\n". Then output each line taking care to
put string values in quotes which means you also need to escape quotes
in the data. After each line echo "\n". That's really all there is to
it.
If you're still having problems I suggest you post the exact code

I don't think you're far wrong with this one. I really think trying to

there are some conversions that never really make sense.

in your experience would dumping a result set of 50-60 rows from mysql

playing with
memcache I don't see an issue but I was wondering if you had an
opinion on
max. size of data for a single entry?
There is a size limit known as the slab size. I believe by default
this is set to 1MB. The only thing to bear in mind is the network
traffic you'll be creating when you store large objects. You need to
weigh up the size against how often you'll be retrieving it.
Personally, if I were anywhere over a few kB in a single entry I'd
look at whether I really need everything in that entry each time or if
it's possible to break it up into smaller pieces.

If you are in that particular situation (which I am), you're basically SOL and the statement above has no bearing. Correct, but you're then breaking one of the rules of the singleton pattern. If you're stuck with that then you'll need to enforce the singleton aspect in non-technical ways (policy, regular beatings, etc).

But apparently implementing them in PHP leaves things to be desired. Not really, not if you do it correctly. As far as I can tell, apart from getting it completely wrong (it would have been wrong in all languages I can think of) the only issue you've come across is not being able to extend a class with a public constructor. If that's the only issue you can find then I don't see much to be desired. I don't know the exact reason for this limitation but I'm sure there's a good one.

On 20 Oct 2008, at 18:07, Christoph Boget wrote:
Ok, so why isn't this working as (I, at the very least) expected?
Hmm, where to start...
class singleTon
{
private static $thisObj = NULL;
private $thisProp = NULL;
public function __construct()
A singleton would usually have a private constructor to prevent non-
singleton instances.
{
echo 'singleTon::__construct()';
if( !is_null( singleTon::$thisObj ))
{
echo '$thisObj already set. returning it...';
return singleTon::$thisObj;
}
singleTon::$thisObj = $this;
1) You don't return it unless it already exists, not that it matters
because this is the constructor and you can't return anything from that.
2) The constructor has no involvement in management of the singleton
instance so this is just all wrong.
}
public static function singleton()
{
echo 'singleTon::singleton()';
if( is_null( singleTon::$thisObj ))
{
$retval = new singleTon();
}
return singleTon::$thisObj;
}
That method has the same name as the class. I'm not sure what effect
this will have but it's certainly to be discouraged.
public function setThisProp( $sVal )
{
$this->thisProp = $sVal;
}
public function getThisProp()
{
return $this->thisProp;
}
}
$one = singleTon::singleton();
$one->setThisProp( 'Joe' );
echo '$one->getThisProp();: [' . $one->getThisProp() . ']';
echo '$one: [' . var_export( $one, TRUE ) . ']';
$two = new singleTon();
echo '$two->getThisProp();: [' . $two->getThisProp() . ']';
$two->setThisProp( 'Bob' );
echo '$two: [' . var_export( $two, TRUE ) . ']';
echo '$one->getThisProp();: [' . $one->getThisProp() . ']';
echo '$two->getThisProp();: [' . $two->getThisProp() . ']';
echo '$one->getThisProp();: [' . $one->getThisProp() . ']';
I would have thought that both $one and $two would be referencing the
same object but they aren't. Apart from making the constructor
private, is there any way I can ensure that there is ever only one
instance of an object?
Here's the simplest example I can think of (untested, typed straight
into my mail client)...
class Singleton
{
static private $_instance = null;
public static function Instance()
{
if (is_null(self::$_instance))
{
self::$_instance = new self();
}
return self::$_instance;
}
private function __construct()
{
// Do normal instance initialisation here
// Nothing singleton-related should be present
}
public function __destruct()
{
// This is just here to remind you that the
// destructor must be public even in the case
// of a singleton.
}
private $var = '';
public function SetVar($val)
{
$this->var = $val;
}
public function GetVar()
{
return $this->var;
}
}
$obj1 = Singleton::Instance();
$obj1->SetVar('arse');
$obj2 = Singleton::Instance();
echo $obj2->GetVar(); // This will echo 'arse'
Singletons are not rocket science, but as with all patterns you really
need to understand the theory before trying to implement and use it.

Re: [PHP] when mysql is down
On 17 Oct 2008, at 16:52, Rick Pasotto wrote: Today my hosting company took down the mysql server for about 1/2 hour. As a result some php errors displayed. Firstly if they didn't tell you it was going to happen then I suggest you change host. Unless it was an emergency, but even then they should have contacted you as soon as they knew it was going to happen. All of my pages have a random quote from a mysql table. If it's not available it's really not a big deal. However, some of the pages depend entirely on data from the database. What's the best way to handle this? If the mysql is required should I redirect to the front page (which doesn't need mysql except for the quote) or show a blank (or error message) content area (navigation would still be available as it's the same on all pages)? The quote is from an include file. What's the best way to output nothing if the mysql connection fails? I realize these are probably elementary questions but any advice would be appreciated. Production websites should have display_errors off in php.ini. This will prevent the site from displaying PHP errors at all. PHP errors can reveal more about your site than you want to share and could potentially reveal holes. To answer your question you simply need to check the return value from the connection function. It sounds like you're not doing this and just going ahead and trying to use the connection regardless. The best way to avoid errors is to not do stuff that will cause them. Ideally if you cannot create the page that was requested you should return a 503 HTTP error, a message indicating a temporary problem and end the script there. Not only does this inform your users that the problem is temporary it also indicates to search engines that they should not index this page right now but that the URL is still valid. -Stut -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

When validating the content of the cookie you would add the secret string and then compare the calculated hash. In both cases the "bad guys" would need to know the secret string in order to create a valid cookie value so as long as you're not stupid enough to share it it's pretty secure. Aside from the extra CPU required for encryption the only difference between the two is that with hashing the value you're storing is stored in the cookie in plain text whereas an encrypted value is, erm, encrypted. I suggest you Google encryption and hashing as these are pretty basic concepts. -Stut 2008/10/15 Stut <[EMAIL PROTECTED]> On 15 Oct 2008, at 15:23, Ben Stones wrote: I've read a few videos on cookie security and it makes sense that people can modify cookie values which is a problem I'm trying to figure out to *try* and prevent.

Before to send login/password over the net, user is directly redirected to HTTPS version of my web application in case he did not write HTTPS:// at the address bar. once he types login/password, everything is checked with DB data and if it is correct, so he's granted right to continue and he redirected to another HTTPS web page. i would like improve security but i'm not sure it make sense as HTTPS is used. SSL secures the data transmission from client to server and there's nothing currently available that provides better security at that level. therefore i was thinking to request for each stored procedures (all my SQL requests are in stored procedures) login and password (stored into session)... but does it make really sense ? First of all, IMHO there are no valid reasons for storing passwords in the session. If you think you have one I'm betting your architecture is either overly complicated or just plain wrong. Secondly, I see no security advantage in requiring a username and password to be passed along with each stored procedure request. Aside from the extra overhead, if someone gets access to your database you have other problems which won't be solved by requiring a username and password to execute stored procedures. -Stut -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Proxies do not necessarily cache web pages - this is an optional feature of the technology. At the most basic level in most implementations they provide a protected bridge between two networks. Proxies can be implemented as shared clusters such that any request going through the cluster could appear to come from one of a number of IPs (i.e. the client is not tied to a single proxy appliance). In this instance you cannot rely on a client always coming from the same IP. In addition it's pretty standard practice for a lot of ISPs to have relatively short leases on their IP pool. This means that a client could move between different IPs between requests. This is unlikely however because I believe most ISPs will do everything they can to issue a connection with the same IP when the lease expires but it's not something you can rely on. In any case you cannot rely on the user not disconnecting their laptop from a wired connection and then connecting to a wireless connection that runs through a different router. This would also change their IP. At the end of the day it's well understood that IP addresses should not be used for authentication or continuity purposes. I've not come across a session implementation that uses them for a very long time. -Stut -- http://stut.net/ Stut wrote: On 18 Sep 2008, at 16:37, David Rocks wrote: Stut wrote: On 18 Sep 2008, at 05:57, David Rocks wrote: I am running a test PHP web app on my local machine that uses REMOTE_ADDR and most of the time ::1 is returned as the IP addr and sometimes it is 127.0.0.1 . I am on OS X 10.5.5 and using APACHE 2. PHPINFO always returns ::1 for REMOTE_ADDR. Is this a PHP or a APACHE 2 thing? It's coming from Apache and is correct. ::1 is the same as 127.0.0.1 in IPv6. Which you get will depend on how you request the page and how your DNS/hosts file is set up. Request it with an IPv6 domain/IP and REMOTE_ADDR will also be IPv6. You should be able to disable IPv6 in your system settings, but from a future-proof point of view you should be able to handle both. -Stut This app uses this test to insure that the page being processed came from the same machine as was used to login to the app. The app is intended for broad use so I can't control the use of IPv6. Is localhost the only case where the value returned might have different values? Can you point to a reference where I might figure out a better future proof test? Using the IP is not a reliable way to check for this. Some ISPs use transparent proxies which can cause each subsequent request to come from a different IP, regardless of whether it's v4 or v6. You'd be better off using a cookie, although that would be a bit less secure. If you really need to use IP then you can probably rely on it not switching between v4 and v6 if you're not using localhost. For testing use the machine's real IP or hostname instead of localhost and this problem should disappear. -Stut -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Here is line 57:

And the info that is trying to grab from the database is:

Now... the error only happens on line 57... On line 56 there is
the same command except: $timein = date("m/d/y h:i:s A",
$row['timein']);
And that doesn't cause any errors so I'm at a bit of a loss as to
what to do? I know I can redirect the warning to an error message,
but I don't want to do that... I am trying real hard to write
clean code... And this is my last error...
It's a total cosmetic thing since it still displays everything
right...
Any ideas? :)
Do a var_dump($row['timeout']) on the line before the one giving
the warning to check that it contains what you think it does.
Hey Stut,
Thanks for the quick response... You were right... I did a var_dump
both on $row['timein'] and $row['timeout'] and the error was because
of the way that I update the records. for time in, I insert a new
record, for time out, I update the record where timeout= NULL and
THAT is what was causing the issue... I guess I can just redirect
that error, ignore it, or come up with a different way to update the
current record without having to use NULL, or maybe, write a timeout
timestamp for like midnight on January 1 1955 or something like
that...
Try "is null" rather than "= null".
