Hi Guys,
I'm looking for some help in buiding up the right queries / code for
this. I have a database that tracks all the plays of my Football Team.
Here are the relevant Fields:-
Formation
OCall
DCall
OYards
Key
The key is an amalgam of the first 3 fields so a typical record might
look like this:-
Formation - I
OCall - RT
DCall - BZ
OYards - 5
Key - IRTBZ
What I want to do is to produce report that looks like this:-
Form
OCall
DCall
OYards - Median
OYards - Mean
OYards < 0
OYards 0 - 4
OYards 5+
So in other words for every combination of Formation, OCall and DCall I
want to report how many times it occured, what the Median and Mean
values were and what the distribution of plays was.
I reckon I'm going to have to create an array and then loop over the
array pulling out the relevant information but are there any special
techniques I should consider?
Thanks
Alan

It seems your message is in Windows-1252 encoding. Make sure you are not
using an encoding in your PHP source code editor that is different from
the encoding of your input data.

Just a couple of questions/points to make all clear:
a) are you aware that the "^" at the beggining inverts its meaning?
b) if you want to allow (or "not fail with") "-", put it as the fist
(or last?) character of the class, since it is used to define
ranges, and this avoids misinterpreting its meaning
c) what regex family functions are you using and what would be the
complete expression?

Just an idea, try putting a backslash before the non-ASCII characters,
perhaps that will force the function to take them literally instead of
making who knows what assumption about them. And let me know if it works
because we use diacritical marks in Spanish, who know when I might need it.

To know what exactly URL was asked use this:
'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'].'?'.$_SERVER['QUERY_STRING']
However when a rewritten URL was used with mod_rewrite Apache module my
code above will simply show you the transformed URL. The real requested
URL in this situation is located into a different location:
$_SERVER['REDIRECT_URL']

I got a message saying that I should use the phpinfo and use the variables
that are given as response, but the problem is that the variable that is
usefull is the HTTP HEADER HOST and I dont know how to retrieve it. I thank
anyone who can help.

For the curious:
<?php
function myempty( &$value )
{
if( empty( $value ) )
{
return true;
}
return false;
}
$foo = array( 1 => 1 );
if( isset( $foo[2] ) )
{
echo 'WTF! :)';
}
print_r( $foo );
if( !empty( $foo[2] ) )
{
echo 'WTF! :)';
}
print_r( $foo );
if( !myempty( $foo[2] ) )
{
echo 'WTF! :)';
}
print_r( $foo );
?>
Cheers,
Rob.

Hi gang:
Question: I know you can set a directory to have certain permissions,
but how do you set the permissions to be recursive? In other words,
for example, if you set the directory to be 755, then everything
placed within that directory will also be 755.

Kim:
Thanks, but are you sure about that?
That looks like a function that simply takes the old permission
settings and stores them until you're finished setting new
permissions to a file/directory and then you can safely restore the
old permissions to what they were.
What I'm looking for is how to set the permissions for a directory
such that all files in it will have the same permissions.
I use GoLive and in their file "FTP access" settings they have a
recursive checkbox. If the checkbox is not checked, then whatever
permission setting I give to a directory is just to the directory.
However, if it the recursive checkbox is checked, then all files
placed in the directory will have the directory's permissions.
Perhaps this is something limited to GoLive and not an option in
setting chmod's via php's built-in functions.
I am aware of how to change the contents of a directory to a specific
chmod using a recursive php routine, but I was looking for a simpler
way.

This is clearly depending on the host OS/ftp daemon and what
permission is set on the upload folder. What GoLive! probably does
with that checkbox is setting permissions through chmod on the ftp
"automagically" after each file has been uploaded.
Do you have shell access to the particular host?

just testing my news connection

Hi everybody,
I have been trying to find a solution to this issue on other newsgroups but
haven't had any luck so far.
My config: Apache 2.0.54, PHP 5.1.2 on Win XP (or 2003).
Here is the outline of my application:
The user submits a form to the server, which is then processed by a php
script. This script calls exec to start a Win32 console which passes some
information to a Windows process, and then returns, thus allowing the php
script to continue. In the meantime, the service keeps working. When it's
done, it creates a file to signal that new data is available. The php script
sees this file, picks up the data and sends it to the user.
Everytbing works if all this happens synchronously, meaning the php script
waits for the windows service to finish before doing anything else. But this
means that the user doesn't see any feedback as to the status of the
operation (and it can be quite lenghty), and it can't cancel it either. So
in order to increase useability, I need the server needs to be able to
perform some concurrent tasks:
1. monitor the status of the Windows service processing
2. provide user feedback about its status
3. listen for user commands, such as cancel, or back, in order to cancel the
current processing
I tried various ideas, using header( ... ) to start other scripts etc, but
so far nothing worked - things always happen synchronously (start
processing, wait for it to finish, show result) which is not what a user
would expect. Also, I would prefer to do everything on the server instead of
using js for example in the browser.
Any help would be really appreciated.
Thanks,
Adrian

What you can do is something usually known as job queuing. It consists
of having a queue, which can be a file on the disk or a database table.
To queue a job, you just add a new record to that job table. Then have a
background process handle it ASAP, and update its status as it
progresses. When the job is marked as done, the requester can delete its
record, while the background task proceeds to the next enqueued job.
Here you may read more about this concept of queueing:

As always, read the docs and check the user comments. You won't need
any more examples :-)
