[PHP] restrict fsockopen spam etc.
Hello List, in last times i recognize that some scripts/formmailer of customers get abused by spammers. Some scripts avoid to use smtp-server and do smtp-dialog by its own using fsockopen etc. Problem ist that if mails are sent by fsockopen directy to other servers they not occur in server-maillog. Only way to find them is viewing accesslog, bit it is really hard to make relations between entries in accesslog and spamreports from other servers. My question is if there is a way to restrict fsockopen to use not port 25 or a kind of logging which makes entries if fsockopen is used. This gets more and more to a problem for us but we do not want to disable fsockopen completely at the moment. Is there a way to realize this? Thanks, Andre

Re: [PHP] Re: restrict fsockopen spam etc.
I think there was a proposed change to allow php to log mail calls. I was disappointed to see it did not get put in to php yet though. Would help to pinpoint scripts being abused, especially in shared environments.

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. Full
details available at http://php.net/usort.
I just ment to say it would be nice to have it like in Java or C# where you
can implement an interface, called Comparable and define a function in the
class called compareTo which returns an integer smaller, equal or greater
than 0 by which elements can generically be sorted by in a collection. Since
PHP has arrays (hash maps) as the primary collection type, and they are very
good for storing sets or other collections, it would be nice to have a sort
function that would look, if the elements of the array have a compareTo
method (implement the Comparable interface), and if they do, then sort with
that. I find it a bit surprising that such a well designed programming
language doesn't have such a useful feature. I guess one could use one of
the gazillion libraries out there to do the same thing. Also, one could
argue that this further checking would slow down functions that are
primarily used for sorting strings. However, the answer could be also in the
ArrayObject class which is in php natively. Only it should implement all the
array functions that are there anyway, which shouldnt be too hard to do for
the PHP PL developers. Some more in depth documentation of that class would
also be helpful.
Anyway, I found a not perfect, but good enough solution:
Implement a static compare function in the class of the object and put a
function in my library, that is simply called myTools::sort that will get
the object class of the first element of the array (if there is one) and
sort according to the compare method implemented in that class (if it
exists), otherwise just use sort. The compare method takes the parameters as
self:
public class AClass { // implements Comparable {
public static function compare(self $obj1, self $obj2) {
return strcmp($obj1-prop1, $obj2-prop1); // e.g.
}
}
That way I will get an exception if there is an object in the array which
does not have that class, but i can live with that. At least i'll get an
exception and not another funny error, because the parameters are self,
right?
It might be better to define an interface called Comparable with that
method, but was not really necessary for my case.
Just a few thoughts to maybe improve PHP in the future. Hopefully there will
be a lot of interfaces and objects for collection types at some stage in PHP
natively, although that might clutter the namespace and could be realised
with libraries. What are your thoughts?

[PHP] foreach and destroying variables for memory saving
Hi All,
Just to annoy the hell out of you, another thing that has been on my mind
for a while:
I love the foreach ($ar as $k = $v) { ... } construct and use it all the
time. However, I read somewhere that foreach actually uses a copy of $ar
instead of the array itself by reference. Wouldn't it be much more
usefull/efficient, if foreach would use the array by reference? Then one
could change arrays while iterating over them (without having to use the old
fashioned for ($i=0; $icount($ar); $i++), also this doesnt work for
associative arrays). I know you can do it with while and list somehow, but i
personally find that language construct rather ugly and can never remember
it. Is there another way that any of you use? Please enlighten me.
I just use foreach because its easy, but it might not be the best. However,
it seems to perform good enough for what i've done so far.
Somewhere i also read that one can save a lot of memory by destroying
variables. Is that done with unset, setting it to null or something similar?
So, i take there is no garbage collection in php? I've never actually looked
at the c source code of php. Maybe its time to actually do that. But it
might be easier if someone can answer this from the top of their head.
Thanks for your patience.

Everything works The only thing I did notice was I had to go back in my ADO code, and specify a port in my connection object (which wasn't needed before)... And now mssql_connect works!

[PHP] Re: foreach and destroying variables for memory saving
Tim | iHostNZ wrote:
Hi All,
Just to annoy the hell out of you, another thing that has been on my mind
for a while:
I love the foreach ($ar as $k = $v) { ... } construct and use it all the
time. However, I read somewhere that foreach actually uses a copy of $ar
instead of the array itself by reference. Wouldn't it be much more
usefull/efficient, if foreach would use the array by reference? Then one
could change arrays while iterating over them (without having to use the old
fashioned for ($i=0; $icount($ar); $i++), also this doesnt work for
associative arrays). I know you can do it with while and list somehow, but i
personally find that language construct rather ugly and can never remember
it. Is there another way that any of you use? Please enlighten me.
I just use foreach because its easy, but it might not be the best. However,
it seems to perform good enough for what i've done so far.
You can use:
$arr = array('abc'='123','ver'=phpversion());
foreach ($arr as $key=$val) {
echo $val.\n;
// Beware! - Changing $val will change it in $arr
}
// or like this:
$arr = array('abc'='123','ver'=phpversion());
reset($arr);
while (list($key, $val) = each($arr)) {
echo $val.\n;
}
Somewhere i also read that one can save a lot of memory by destroying
variables. Is that done with unset, setting it to null or something similar?
So, i take there is no garbage collection in php? I've never actually looked
at the c source code of php. Maybe its time to actually do that. But it
might be easier if someone can answer this from the top of their head.
Thanks for your patience.

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. Full
details available at http://php.net/usort.
I just ment to say it would be nice to have it like in Java or C# where you
can implement an interface, called Comparable and define a function in the
class called compareTo which returns an integer smaller, equal or greater
than 0 by which elements can generically be sorted by in a collection. Since
PHP has arrays (hash maps) as the primary collection type, and they are very
good for storing sets or other collections, it would be nice to have a sort
function that would look, if the elements of the array have a compareTo
method (implement the Comparable interface), and if they do, then sort with
that. I find it a bit surprising that such a well designed programming
language doesn't have such a useful feature. I guess one could use one of
the gazillion libraries out there to do the same thing. Also, one could
argue that this further checking would slow down functions that are
primarily used for sorting strings. However, the answer could be also in the
ArrayObject class which is in php natively. Only it should implement all the
array functions that are there anyway, which shouldnt be too hard to do for
the PHP PL developers. Some more in depth documentation of that class would
also be helpful.
Anyway, I found a not perfect, but good enough solution:
Implement a static compare function in the class of the object and put a
function in my library, that is simply called myTools::sort that will get
the object class of the first element of the array (if there is one) and
sort according to the compare method implemented in that class (if it
exists), otherwise just use sort. The compare method takes the parameters as
self:
public class AClass { // implements Comparable {
public static function compare(self $obj1, self $obj2) {
return strcmp($obj1-prop1, $obj2-prop1); // e.g.
}
}
That way I will get an exception if there is an object in the array which
does not have that class, but i can live with that. At least i'll get an
exception and not another funny error, because the parameters are self,
right?
It might be better to define an interface called Comparable with that
method, but was not really necessary for my case.
Just a few thoughts to maybe improve PHP in the future. Hopefully there will
be a lot of interfaces and objects for collection types at some stage in PHP
natively, although that might clutter the namespace and could be realised
with libraries. What are your thoughts?
You can already do what you want. Implement it yourself. Not everyone
wants this level of cruft and inefficiency.

Re: [PHP] usort for sorting an array of objects
You can use a (base) object Comparable with a method compareTo as the callback
function for http://php.net/usort
That gives you 99% of what you want, for the tiny price of having to pass in
the array('Comparable','compareTo') as the callback arg.
Given that one frequently calls usort and friends on arrays of data that are
NOT objects at all, and, arguably, even on arrays of disparate objects or
objects and non-objects, what would you expect to happen?
usort(array(new Foo, new Bar, 42, new Baz, 'expected outcome?'));
Assume Foo, Bar, and Baz all have different/unique incompatible compareTo
methods.
PHP is not Java.
Trying to force it to do things the Java way means you probably need to spend
more time understanding the preceding sentence.

[PHP] PHP OFX connection
Hello, No doubt some of you have heard of Quicken, Quickbooks, Microsoft Money and other providers. Apparently there is a data format called OFX (Open Financial Exchange) that these software packages use to download transaction data from banks. Just wondered if anyone in PHP land had successfully created a PHP-based system to connect to a bank's server and download OFX data and consume it. I'm looking to find a way to help reconcile our bank accounts with multiple sources of transactions that can come in and confuse things. Thanks Dan

Re: [PHP] usort for sorting an array of objects
Inefficiency for me is when it takes longer to code. How long can this take? Even if you go full-blown with an Interface and static methods that have to be fleshed out in the implementations, you're still talking about an hour or so. Quit complaining and start typing. :-) PHP is a scripting language. Everytime the compiler has to parse the source. No. The source is compiled once, and your callback is a PHP function pointer passed down to the C function for usort. That C function has to call back out to the PHP function pointer. That is slow compared to a all native C, perhaps, but it's not re-compiling your PHP source function on every call to the compare function. Even if you are comparing across script calls, APC or ZendCache or similar will compile once. The slowness isn't even in the compiling anyway, really. It's in hitting the disk drive to LOAD the PHP source. It's just as easy to cache the parsed byte-code as it is the source, and it saves a few more cycles, so the caches store the byte-code; But the real savings is not hitting the hard drive to get the PHP source. You can not except true OOP performance. If you REALLY want performance, OOP has enough overhead that you can re-factor to strictly procedural or functional and squeeze out a bit more :-) Not too many device drivers written in C++ OOP behavior is okay.

I'm assuming you meant get records one week less than the current system
timestamp.

Right - because it's not going through your mail server.

My question is if there is a way to restrict fsockopen to use not port 25 or a kind of logging which makes entries if fsockopen is used. Block it in the firewall? Local mail gets redirected to a dedicated mail server (which is allowed in the firewall). Everything else has port 25 blocked.

No need to pass AdminID in the URL at all. Store that ID in the
AdminLogin session variable instead of OK and you can get it from
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?

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

The scripts executing the task update a status JSON file in the tasks' working directory, which is the only thing being read by the browser after it's kicked off the import process by calling the daemon server with the list of files to import. i've taken a look at popen() and think i can indeed get it to work with that.. i'll let you all know in this thread where to view a demo, when it works :) Cool, would like to see it in action. In case you haven't thought of this and it's relevant: If ffmpeg is writing out a file and you can estimate the final size, you could check the file size, if it's growing that is, and compare it to the estimated final size to show the progress. Maybe not the best solution but if there is nothing else. i've thought of it, and considered it too random to even try to estimate ;) OK. So you have tried converting a couple of vids and the resulting file size is always random? Surely there must be some kind of relation to the input file size, the transcode parameters and the output file size. Of course it also depends on the nature of the video but you could also take into account the file size and the time it took to get to that file size (during the process) in relation to the input file size. If you don't mind, i would like to know some good parameters for ffmpeg to convert video files to flv format. Might use it in the future. $cmd = 'nice -n 19 ffmpeg -i '.$sourcePath.' -b 500 -acodec mp3 -ab 192 -ar 22050 -y '.$destination.''; that's what i'm using now. it spits out files larger than the divx originals that i'm using for testing purposes. -b number is used to set the quality and size of the output flv usefull too; http://www.catswhocode.com/blog/19-ffmpeg-commands-for-all-needs Thanks. -- Tim-Hinnerk Heuer http://www.ihostnz.com

I would simply write a function called

$intersection = array_intersect($m_array[$i], $intersection);

return $intersection;

and put that into my library. O and while i'm at it, the array_reduce way
would prob be:
$m_array =
array(array(green,red,blue),array(green,yellow,red),array(green,red,purple),array(green,red,yellow));
array_reduce($m_array, 'array_intersect');
I tried this now with array_reduce and it didn't work as i expected. Can
anyone tell me why?
It says argument #1 to array_intersect is not an array, although i have an
array of arrays. Also tried providing $arrayOfArrays[0] as the third
parameter to array_reduce which had the same error.

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.
Full
details available at http://php.net/usort.
I just ment to say it would be nice to have it like in Java or C# where
you
can implement an interface, called Comparable and define a function in
the
class called compareTo which returns an integer smaller, equal or greater
than 0 by which elements can generically be sorted by in a collection.
Since
PHP has arrays (hash maps) as the primary collection type, and they are
very
good for storing sets or other collections, it would be nice to have a
sort
function that would look, if the elements of the array have a compareTo
method (implement the Comparable interface), and if they do, then sort
with
that. I find it a bit surprising that such a well designed programming
language doesn't have such a useful feature. I guess one could use one of
the gazillion libraries out there to do the same thing. Also, one could
argue that this further checking would slow down functions that are
primarily used for sorting strings. However, the answer could be also in
the
ArrayObject class which is in php natively. Only it should implement all
the
array functions that are there anyway, which shouldnt be too hard to do
for
the PHP PL developers. Some more in depth documentation of that class
would
also be helpful.
Anyway, I found a not perfect, but good enough solution:
Implement a static compare function in the class of the object and put a
function in my library, that is simply called myTools::sort that will get
the object class of the first element of the array (if there is one) and
sort according to the compare method implemented in that class (if it
exists), otherwise just use sort. The compare method takes the parameters
as
self:
public class AClass { // implements Comparable {
public static function compare(self $obj1, self $obj2) {
return strcmp($obj1-prop1, $obj2-prop1); // e.g.
}
}
That way I will get an exception if there is an object in the array which
does not have that class, but i can live with that. At least i'll get an
exception and not another funny error, because the parameters are self,
right?
It might be better to define an interface called Comparable with that
method, but was not really necessary for my case.
Just a few thoughts to maybe improve PHP in the future. Hopefully there
will
be a lot of interfaces and objects for collection types at some stage in
PHP
natively, although that might clutter the namespace and could be realised
with libraries. What are your thoughts?
You can already do what you want. Implement it yourself. Not everyone
wants this level of cruft and inefficiency.
Inefficiency for me is when it takes longer to code. For one second of
coding time I can waste 1000ms of processing time without any cost. Think
about what a computer can do in 1000ms. Calling a function generically takes
next to nothing in processing time (maybe 0.5ms or less. In fact some db
queries take less than that in my experience...
Regardless of your personal implementation preferences, PHP offers a
sorting mechanism, it's up to you to massage it into your personal
paradigm of the day.
Cheers,
Rob.

[PHP] Need help on MySQL query
Hi Experts, EID Mubarak to all. I need your help on writing a MySQL query.

If your database doesn't have an operator to perform running totals, it is possible but the result usually involves correlated subqueries that usually result in expensive triangular joins. (I think MySQL might have something that will work, but I haven't tried it. STW for MySQL and running sum and you'll find some discussion that should get you going.) If you decide to do the calculation in SQL, you should modify your table definition slightly: CREATE TABLE transaction ( `id` int NOT NULL AUTO INCREMENT, `date` datetime NOT NULL, `withdrawn` double (12,2) NOT NULL DEFAULT 0.0, `deposit` double (12,2) NOT NULL DEFAULT 0.0 ); The value of `withdrawn` and `deposit` should never be NULL. The value of NULL in SQL is essentially an UNKNOWN/MISSING value. That's why SQL calculations that involve NULL yield a NULL value. With the example you posted, it would be like saying When I went to the bank December 1, I deposited 1.00 but I don't know how much I withdrew. What would you say the net value of such a transaction would be? In your database, neither `withdrawn` nor `deposit` should be UNKNOWN/MISSING. (At least I would hope not!)
