RE: [PHP] utf8 encoding £ to £ problem
Hi Chris, Do you use £ or £? I've had problems uploading onto a linux box for ages, but a straight text £ never seems to work, so I have to get one of my colleagues to do it instead... Does that help?

[PHP] Process of creating invoices requiring human thought!
Im creating an invoicing system for a childrens nursery, and Im trying to work out how I can replicate the thought process one would normally go through when working out the bill for each day. Ive created all the mysql tables that I think I need, with all the info possible; along the following lines (Im only showing whats relevant): Child -> childId, starttime, endtime Fees -> feeId, starttime, endtime, rate (£) The easiest way to explain this is as follows: The nursery fees are broken down into AM (8am to 12.30pm), PM (12.30pm to 6pm) and All Day (8am to 6pm), and furthermore theres an hourly rate for extras. Child A starts at 9 and finishes at 5 therefore they come under the all day rate Child B starts at 8.30 and finishes at 12pm therefore they come under the AM rate Child C starts at 9.30 and finishes at 1pm, and because its not a straight they do AM, PM or All Day, theyll probably fall under AM, cos its including lunch. Can anyone see an easy way of putting that sort of human thinking into a script? Any guidance would be gratefully received Just to give a bit more background, there are two nurseries (at the moment) and they have different session times, so the fees table does need to have the starttime and endtime. :-( Cheers Nunners
[PHP] RE: Error Reporting for file commands
Sometime ago, I posted the email below, regarding some problems with a file manager we have developed for our users. The problem still exists, and is now starting to cause "complaints". Mainly from my manager, who's fed-up with receiving the error emails from the system, but it must be annoying users! The scenario is; we have a fairly large Linux cluster, with a RAID disc. Obviously because of the number of disc calls, there's a fair amount of caching. We think the problem is related to this, and would ideally like purely to suppress the error, as it's normally when the script is trying to delete something already deleted. I've tried turning off errors (error_reporting(0)) and indeed using @ on all php file system calls, but it still triggers an error. Does anyone know of any issues with suppressing errors on the following functions? - unlink - mkdir - copy - scandir All of these fail sporadically, even with the above error stuff turned off, and trigger an error.

RE: [PHP] Re: New Large Scale Project.
I can strongly recommend Joomla - I have it working with Menalto's Gallery2, and just got a phpBB bridge working as well. Can I also recommend you use Joomla over Mambo? About a year ago the core developers (now at Joomla) fell out with the so called owners of Mambo, about ownership and future developments so they created Joomla. They're in the process of developing v1.5 which is going to have some really cool features, mainly for 3rd party developers, so although you may not experience the features with it's direct release, other components and modules are already being developed that will improve the CMS no end...

I've used the bridge components and Menalto Gallery and it works pretty well. THere are various core hacks you can apply too to setup varying permission levels and other stuff. Simple Machine Forums also has a good bridge component (it's what the Joomla forums themselves use). So with a little fiddling you can probably make Joomla do what you need.

Heres the function - sometimes the scandir fails, sometimes the unlink,
sometimes the rmdir at the end. They all have @ to try and surpress the
error, but I think it's a system halt failure - I can only assume?
You'll also see there are quite a lot of clearstatcache - that was another
attempt to sort this problem out!
function system_rmdir($dir) {
$current_error_level = error_level();
error_reporting(0);
$dir = $dir."/";
$dir=str_replace("//", "/", $dir);
clearstatcache();
if (is_dir($dir)) {
$dir_contents = scandir($dir);
foreach ($dir_contents as $item) {
clearstatcache();
if (is_dir($dir.$item) && $item != '.' && $item !=
'..') {
system_rmdir($dir.$item.'/');
} elseif (file_exists($dir.$item) && $item != '.' &&
$item != '..') {
@unlink($dir.$item);
}
}

[PHP] FTP - moving/copying files
I'm setting up an ftp manager which allows a user to connect to their space on an external server. All the php-ftp functions work fine - after I'd realized how to use the passive functionality - see previous email to list! I've also got working the download and upload functionality, which is quite nice, but annoying - it doesn't allow you to download the file without creating a temporary version (whereas if it were a local copy you'd be able to copy it to a variable, then echo it out... Finally, what I now need to do it be able to move/copy files within the FTP space. The standard FTP commands (mv & cp or copy) are not featured in php-ftp functions. Does anyone have any suggestions bar copying the whole lot to a local drive then upload in the new space? Cheers Nunners
RE: [PHP] FTP Problems
Ah - whoops - just worked out why - you need to set the passive mode after
you login, not after a connect! Silly solution!

you could try '~/' (or maybe just'~') as the dir name which equates to the
'the current users homedir' when you in a shell - no idea whether that is
even allowable
when going in via ftp but might be worth a shot though - given what you have

[PHP] PHP Session
Hi Folks,
Bit of an unusual question here, which is basically as a result of my lack
of understanding as to how Sessions work.
I've created a Captcha image solution for an application I look after, and
when we came to look into something that required debugging, I realized I'm
using sessions without understanding how they work.
Basically, the login includes an image, and textbox for the captcha text.
The image then generates a session with a variable name of x, and a value of
the characters from the captcha image. The user then logs in, including the
text on the graphic.
## IMAGE CODE:
session_start();
$_SESSION['captcha_text'] = $randomly_generated_text;
The login check page obviously checks the username and password, and also
does the following:
## CHECK LOGIN CODE
session_start();
if ($_SESSION['captcha_text']!=$_POST["captcha_text"]) {
#FAIL LOGIN TEXT
}
session_destroy();
It works a treat, however what I want to understand is how the session is
kept relevant to that particular user's session - mainly because my boss
wants to check there's no security implication.
We've thought this through and believe that in other applications, there is
also a cookie or post/get variable set in the form, which includes a
reference to the session name.
Are we missing something, or is it really magic?
Cheers

RE: [PHP] Array Sorting
I think I may have written down my variable structure incorrectly in the
first place, which even has me confused...
The $file_array[$filename] is I don't think a further array.
The "sub" values are created as follows:
$file_array[$filename]["Date"] = ...
$file_array[$filename]["Size"] = ...
Looking at usort, it will put the list of Dates in order (by doing a pure if
is bigger or smaller...) but will loose the link between the particular
filename and it's date properties.
Does that make sense - or am I loosing the plot?
Am I also making a mistake by not defining $file_array[$filename]? I don't
think so, but would be happy to be corrected!

reasons for not running the pcntl functions under the web browser are - is
it down to security?
cheers

NO WAY!
pcntl should NOT be run in a web-hosted environment, according to the
docs.
I don't think Zeus' threading model is going to make it "okay" to use.

pctnl should only be used from CLI/CGI
The examples should be sufficient for that, but you don't really care,
as it's not useful for what you want.
Here is what *I* would recommend:
Create a new table of "searches":
create table search(
search_id int(11) auto_increment unique not null primary key,
status enum{0, 1, 2} default 0,
search_pid int(11) default null,
inputs text,
results text
);
0 = new search
1 = in progress
2 = complete
Now, when somebody wants you to do a search, just insert a record:
$query = "insert into search(inputs) values('$CLEAN[inputs]')";
where $CLEAN is your sanitized validated $_REQUEST input, of course.
$id = mysql_insert_id();
Your scrolling banner can than have a META Refresh of a few
seconds/minutes/whatever, and embed the $id into the URL for that.
See: http://php.net/mysql_insert_id
Then, of course, you need something to actually PERFORM the searches,
which is where a nice cron job comes in.
That cron job can start a new search task which will do this:
[in psuedo-code]
$pid = getmypid(); // or something like that:
UPDATE search set status = 1, search_pid = $pid where status = 0 LIMIT 1
SELECT id, inputs from search where search_pid = $pid
$id = $row['id'];
update search set status = 1 where id = $id
//do the search
//when done:
update search set status = 2, results = '$search_results' where id = $id
Doing it this way means you could even run several processes at once,
each working on a different search.
Note that the UPDATE marks the record as "in progress" and ties it to
the process running, so that there is NO race condition.
If MySQL does not support LIMIT 1 in an UPDATE, which I'm pretty sure
it does, but not 100% certain, then you'd have to just update all the
inputs available, and have the thread handle each search that it
"took" in the UPDATE.
You could still have an army of search processes, though, as new
search inputs are coming in all the time, and each search process
would handle however many were on the "To Do" (status 0) stack when
they started.
This is very scalable, and you could even buy more computers and throw
them at it, with just one database, provided you tagged the process_id
with a machine_id of some kind as well, to avoid duplciate process IDs
on 2 computers. I'll leave that part as an exercise.

[PHP] Forking a search - pcntl
I'm creating a search function as part of our webmail frontend, however I'm having big problems with timeout etc. What we'd like to do is run the actual search query in the background (i.e. fork) while the viewable page shows a nice scrollie banner etc! Due to various problems with the server we are using (Zeus) we can't just run an exec(). I've had a look around, and it would seem that pcntl maybe the way forward. Does anyone have an example working script, or indeed a decent tutorial on how to use the functionality? The php manual has limited information on using the functions, and I just can't get my head around how it's meant to work?!!! Cheers Nunners
[PHP] imap_search and multiple criteria
Does the imap_search support multiple criteria? I've got the following successfully returning the correct results: However, when you try and put them in the same search e.g. $search = "BODY \"test\" OR SUBJECT \"test\"" It fails... The only way in which I can see this can be done is by joining the various arrays that are returned. Is this best? Thanks Nunners

[PHP] Improving a MySQL Search
I'm creating a serious of pages that show various aspects from a Syslog output. The main information is currently stored in one MySQL table - which after having been run for about 2 and a bit months has got nearly 100 records. With this amount of information, it's taking a large time to carryout even the simplest query. Someone has suggested I look at setting up an archive, for slower searches, and a more recent table for quicker searching, but I'm reluctant to do this, as it would take quite a bit of time to copy all the information across as it stands, and then also to run a cron which transfers between the live and archive. Can anyone suggest some quick easy methods for speeding up the search? Cheers James

[PHP] Multiple POP accounts on Webmail Front
Hi All, Bit of a side question, but it's still php related. Does anyone know of a Webmail client, preferably open-source, that is able to support single login, to allow users to collect and use multiple POP3 or IMAP accounts? I'm currently using Ilohamail, and have used Squirrel in the past, but neither, I don't, think support multiple POP3 accounts on one login. Any ideas? Cheers James
[PHP] SQL sums
I'm trying to create a table, and ultimately a graph, out of some syslog data. I have a mysql table with the following info in it: Time (unixtime stamp), bytes rcvd and bytes sent I want to create a sql statement that group the data over a certain period of time, and produces the following table: Time Sent Rcvd >From x to y Total bytes sent during period x to y Total bytes rcvd during period x to y >From y to z Total bytes sent during period y to z Total bytes rcvd during period y to z >From z to a Total bytes sent during period z to a Total bytes rcvd during period z to a >From a to b Total bytes sent during period a to b Total bytes rcvd during period a to b Now to create this I've tried a horrible method of using php to call sql table, and then go through each one, and add it to each period of time as appropriate. it's messy and slow! What I want to do is have the mysql do this.is it possible? Cheers Nunners
