Code igniter, a php framework can do this with one call. It could be worth
looking into

I'm not sure CodeIgniter would be of any help here. I don't recall any
function in the CodeIgniter framework that lists directories like this,
so he'd still have to end up coding it himself.
Also, python tends to be used more for command line stuff than websites.
CodeIgniter does have a CLI extension, but the app would just be
severely bloated running an entire PHP framework for what might only
need a light script. Bit like using a sledgehammer to hammer in a thumb
tack, can be done, but not really the best tool for the job.
Thanks,

Haven't tried yet, but isn't that what $ is for? End of line?
And exec only gives one line- the last line of the output of the

$ matches end of line, but since your last match expression is to
match explicitly the character '.' before end of line, and there's a
newline, it won't match. Again, use trim() to get rid of the newline
character at the end of the string returned by exec(). Looking at the

Thank you for that- that did it. I removed the \.
I am a little confused though; that regex was tested on several test
sites and was deemed accurate on them, and one of them actually supplied
the preg_match code. And if I run the command on a shell it actually
outputs exactly the right subject for the regex- not to mention it got
printed inadvertently (using system() ) via the php exactly the same. So
I don't think I missed it somehow.
What I have constantly seen come up (shell and php/html) is: Mixer vol
is currently set to 75:75. (including the period)
Don't get me wrong- you guys make sense; my system doesn't. I need to
get to the bottom of this so I can ensure my code will port well. I
don't want to get it all working and find it breaks when I run it on
another system, albeit same OS (FreeBSD). Could be updates or variations
of releases.
Just to check again, I ran the command on the shell again and sure
enough the period is no longer there- but I can't for the life of me
figure out when that changed as this code has never worked (and yes, I
added in the \. to match the end of line because it originally wasn't
working). Another great mystery? Weird... :)
Thanks again guys.

Hey guys,
I've never run into this before.
I have a field in mysql for page views.
So I pull out value and do +1 to new value - after UPDATE SET it has
incremented by 2?
$val = $row['a_downloads'] ;
$new_val = $val+1;
mysql_query("UPDATE cbn_articles SET a_downloads='$new_val' WHERE a_id =
'".$_GET['id']."' ");
Any ideas? What am I missing?

a_downloads wouldn't happen to be an autoincrement value, would it?

IIRC, the auto_increment should only increment on an INSERT statement and
the field is omitted. Besides, in MySQL, auto_increment must also be part
of the primary key. From Richard's query, I'd say that his primary key
field is most likely a_id. IMO, the best way to count something is to set
the field to an int(eger) type. Then just run 'UPDATE table_name SET
count_field = count_field +1 WHERE criteria_column = $criteria'. This is
more safe as you many have simultaneous users downloading. This would
ensure an accurate count, whereas your logic wouldn't.
Regards,
Tommy
PS: Richard, you should validate and sanitize all inputs. Your query is
prone to injection attack (deletion of rows or your entire DB deleted). Use
either mysql_escape_string or, better yet, mysqli to prepare the statement
and bind the parameters.

Hey Tommy,
I get the same when seting it to a_downloads=a_downloads+1
It still increments by 2
I've never run into this before.

And what difference will that make if the document is requested twice with

Things to consider as part of your application design/flow:
1) Are you doing all PHP processing (application initialization, DB
retrieval, user preference settings, etc.) before any header, echo, print,
printf, output buffer, etc... ? At which point is the update done?
2) Are you sure the DB update is only called for or included/required once
for that particular URL request?
3) Do you any have other page (js - or in page ajax calls, css, php, html,
etc) that requests the page (with the update) again, as Peter mentioned?
It will help you if you do an UML or a flow chart of the application flow.
Regards,
Tommy

Because you're running the query as a response to a GET call, the
browser is allowed to call it multiple times and grab select parts of
the output to speed up rendering of the page. I've run into this before,
and it's annoying.
There are basically two ways to prevent this. Have the page called as
part of a POST request, which is preferred as GET requests should never
change data, hence why browsers are allowed to request them in a
slightly different way to speed up the page display times.
The second way is to also update a timestamp in the DB, and then before
you update check to see if it has been updated within a certain time
period. Depending on what you're updating this for (stat counter, etc)
then this may not work.

Hi all,
I am playing around with PHP and BBCodes and have found some regex's
that should transform my BBCode into correct HTML when rendering.
However, I have found that if the BBCode is not correct (eg missing
closing tag), the regex completely eats my input and my page is empty!
The regex I'm using is:
/\[i\]((\s|.)+?)\[\/i\]/
And with an input like:
This is [i]italic.
I get nothing back.
What I would like is that when no closing tag is found, the opening tag
should just be shown as-is. Anybody have any idea how I can do this?
Thanks!
