Hi there, I'm going to create a small chat script with PHP. The
messages you want others to see will be added to a flat file (I.E.

reading and displaying to be periodic. This means that I want PHP to
check the file for new lines every,say, fifteen seconds. How may I do
that? I have been unable to find any function that acts like a timer.
For handling periodic tasks in a web environement, I use a little
persistent object (stored using APC) that has it's "process()" method
called on every request. Internally it knows when it was last run and
will actually only do work in it's process() method if it's not been
called for a while.
When this work is done, the user's request is obviously slowed down
slightly, but not in a noticeable way.
If you don't need something this self contained, then a normal cron job
is needed.
All that asside, I'm not sure you're asking the right question. If
you've got a chat system, then the client side is presumable a web
server. You can't really push information from the server side to the
client, so you really need to pull it from the client side. Usually
you'd have a javascript timeout that submits an ajax request to the
server and displays any new messages to the user. In this case, PHP
doesn't need to be timed, the client is pulling periodically so it's the
client that sets the timer.

If the goal was to push data, the OP could investigate the use of a
comet server. It holds a long running stream allowing the server to
push new data to the client.

hi...
is this a php/web based app...
are the users using the chat function via the browser..
if this is a browser/web app, are you looking for a way for the
php web app to refetch the textfile... i would assume so...
have you figured out a rough architecture/design for your app..
in your design, you're going to need to figure out how to
accomplish updates to the text file, and when you do, you'll
also have figured out how to do the reads...
i'm assuming that you don't want a continuously running thread
for your php/web app.. ie one continuously, never ending loop...
-so you'll have the user add some text, the app will write this to
a file..
the user will either select a refresh kind of btn, or your
app will have to implement a refresh process, which will then
fetch new/updated data from your files..
etc...

If you're on Unix then look into using cron. Type the following at the
command prompt to get info on cron:
man 5 crontab
Cron tasks can be scheduled at most once per minute. And if you're
using Windows then I believe the equivalent would be task scheduler,
but I've no idea how you would go about using it.

In this case I'm expecting input from both forms and links, so have to
use $_REQUEST, really. As far as I can tell, $_REQUEST is no less safe
than any of the others, as they are all getting their data from the
user, so it's all unsafe until validated/cleaned.
Thanks for the ENT_QUOTES thing, I really haven't had my head screwed on
the last few days!

Why do you want the process to continue indefinitely? Is it for a daemon

Are you meaning like rotate it so that at 90° it will appear as a
pixel-wide line on the image?

He treats the image as width, height and 1 pixel of depth.
It should not be a problem as long as you finished Kita Yud Bet with 5
points of math (trigo & vectors) ;)

Hi Daniel,
I had the same question a short while ago and the only answer I could
find was to redo the image with either gimp or PhotoShop an save it as
png 8 with transparency. The only downside is that this seems to leave
the angled frame (if you use one) a bit scuzzy; but you dont need Z. The
other downside is that you can't dynamically rotate the image. Of
course, I am assuming that by "rotate" you mean turn it at an angle and
not "replace by other images".

eddie,
you were quite right and i was wrong.
after discovering that the longest utf8 varchar column that mysql will allow
is varchar(333), i did some tests. on a varchar(255) column, mysql allows
strings with up to 255 utf8 characters to be inserted. and it truncates at
255 characters observing utf8 character sequences.
now i have to go back to the script that convinced me otherwise and figure
out what i misunderstood in it.
section 10.4.1 of the manual could be explicit about it. when i read it i
got the clear impression the parameter referred to octets.

I've built a certain system where every time new user enters it creates a
"guest row" on "guests" table. he also gets an identifying cookie.
The table contains several fields, one of them is ID which is auto increment
and unique
When he does a certain action it gets recorded in the "done_action" table
with several fields on it, one of them is "guest_id" and his ID on it.
Problem is the guests table has about 30,000 rows (which means ID is high).
I was wondering whether I should somehow change how the system works.
I've thought about couple of options
A weekly "cleanup" job. opens a table called "guests_tmp", *copies* all data
from guests to guests_tmp.
every row it copies it also changes the ID on the table done_action.
What do you think?

Just use SERIAL id and you will be good ;) (that's an alias for something
like BIGINT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY)
It shouldn't bother you as long as it works.

I think your problem has nothing to do with high IDs. I have tables in
MySQL with primary key IDs that have recently passed 2 billion and
they're still as responsive as they were with 1 row!!
What specific operations are slow, and are you sure it's the MySQL
query that's being slow and not something in the surrounding code? If
it is the MySQL query what is it and what engine are your tables
using?

I wish to be able to edit db field that is displayed in a page by
calling up another page to handle the editing.
The problem is how to pass the id (number) through an href. In other
words, can the number be included in the uri and then filter the uri to
leave just the number?
Is something like this at all possible?

Oh dear $DEITY. Please find a beginners tutorial to PHP and complete
it before asking questions on this list.
http://www.example.com/index.php?id=12345
will give you
$_GET['id'] == 12345

The problem is how to pass the id (number) through an href. In other
words, can the number be included in the uri and then filter the uri to
leave just the number?
Is something like this at all possible?
I stopper answering your questions because of questions like this.
Please understand that this question is so trivial that it clearly
demonstrates you have no interest in solving problems yourself
through even the most cursory glance at the php manuals. Instead, you
would rather add to the noise of this list than look. That's
unfortunate.
If you're not going to try to help yourself, then why should anyone help you?
Cheers,
tedd

This preg_replace() should simply replace all "&" with "&" unless the value
is already "&"
But; if $value is simple a quote character ["] I get ""e". e.g., "test" =>
"e;test"e;
Search string and replace works as it should in Regex_Coach.
echo $value.'<br />';
$value=preg_replace("%&(?!amp;)%i", "&", $value);
echo $value;
I tried using \x26 for the "&" in the search string; didn't help.
This seems too obvious to be a bug. Using php5.2.9

Your code works for me, unless I'm misunderstanding the problem. With
the following:
$value = ""e;test"e;";
I get:
"e;test"e;<br />
&quote;test&quote;

I may not have been very clear. Feed it just "test" with the quotes. You
should get back, "test" the same as you gave it. Instead, I get back
"e;test"e;
Like wise, if I give it just a single quote ["] I get back ["e;]

I tried IE8 thinking it could be a weird browser bug. Same error.

I erred when I keyed this message. The "But,...." should be as, without the "e"
on quote. Which is an HTML entity for quote.
But; if $value is simple a quote character ["] I get """. e.g.,
"test" => "test"

Hi!
I'm stuck.
I don't understand why the php CLI dies after 3 hours in my script.
Any idea to solve?
Thanks

The while loop will continue executing until its condition is false. As
you've got a boolean true as the condition, it will never end.
Thanks

I don't want to stop, but the process dies.
I've tried the same loop with bash interpretor.
Same result, it seems to be a ubuntu problem, not a php problem.
Thanks
Why do you want the process to continue indefinitely? Is it for a daemon
of some kind?
Thanks

No, it isn't a daemon, but it does something and wait the end of
processing by polling a daemon.

If that is regular HTTP, why don't you try an HTTP client class that
lets you customize your request parameters like this one?

Thanks. I need to access remote data via TCP. Connecting to the given
port has been successful but getting acknowledgement from the remote server
after sending the login packet is a problem. Is there anything wrong sending
the login packet in strings? or what is the best way?
I probably think the server is not detecting the end of the login message.
Is there anyway you can add END of message to login package specified.
