Hi there,

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.

Like Shawn, I have tried your code in isolation and only get the expected
results. I looped it over a few test values:
?php
$valueList = array('','test','testtest','testamp;test');
echo pre\n\n;
foreach ($valueList as $value) {
echo Before: $value\n;
$value=preg_replace(%(?!amp;)%i, amp;, $value);
echo After: $value\n\n;
}
echo '/pre';
?
outputs (ignoring pre as that was just to remove the br / for easy
reading):
Before:
After:
Before: test
After: test
Before: testtest
After: testamp;test
Before: testamp;test
After: testamp;test
The only conclusion is that something else in your code is converting the
quotes. Have a look around.

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.

As I have already mentioned, you can read the whole derivation of this 3d
perspective engine and write it down using GD. It should not be such a big
issue.
Good luck!

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?

[PHP] include file in a class with global/parent scope?
Hello,
I understand the why $vars is not in the global scope, but i was
wondering if there was a way from within the class file to include a
file in the parent's scope?
i tried ::include('vars.php'), parent::include('vars.php'), but this
breaks syntax...
Please consider the following three files:
'scope.class.inc'
?php
class CScope {
public $var = 'class scope\n';
function cinclude($filename) {
include('vars.php');
echo In class $vars\n;
}
}
?
'vars.php'
?php
//global $vars;//if this line is uncommented then the desired result is
achieved however, i don't want to change all the variables to global
scope (this file is includeded in other files where global scoped
variables is not desireable).
$vars = 'vars.php scope\n';
?
'scope.php'
?php
include('scope.class.inc');
$object = new CScope;
$object-cinclude('vars.php');
echo In original $vars\n;//$vars is not defined***
?
Thanks,
dK

[PHP] Uniquely identifying an array... as a key to another array
Alright, here's the situation. I'm wrapping memcached, which takes a list of several servers, into a quasi-singleton. In other words, I want only one instance per set of servers, not per server. Assuming I had three memcached servers at localhost, 192.168.1.1 and 192.168.1.2, I wouldn't want one instance per server, but given that there are seven possible permutations of combinations / only one server configuration, MemcacheConnector::$instances could be an array with seven objects. I'm expecting MemcacheConnector::getInstance($array) to take an array formatted like 'server' = 'port'. Thusly, the question then becomes, what's the lightest possible way to store a unique-ish array as the key for MemcacheConnector::$instances? Having MemcacheConnector::getInstance() check for self::$instances[serialize($serverArray)] seems a huge waste of both ram and CPU time. Is there a better way? Thanks, Eddie

[PHP] Sorting mySQL query - one order from multiple fields
Hi all. Am trying to sort baseball games by time, where there can be up to 3 times listed per game. Each game has an original date and time field, plus fields for 2 rain-out dates/times (rodate1 rotime1, rodate2, rotime2), to use if the game gets rained out. Note that rotime1 and rotime2 are NULL if no time has been entered. Also note that the original date and time fields are not changed - they are kept for posterity. Usually, the rain-out date is set to a day that the teams were already going to play each other again, with the rain-out game going first. So need to sort those 2 games in order: rain-out first, then normally-scheduled. But, I can't just sort on the time field, as the rain-out game could now have a different time. I need to use the rotime2 (if it exists), else use the rotime1 (if it exists), else use the time. Can not get my query order to work. One of the variations I've tried: $theQuery = mysql_query(select variousFields from theTable where date = '$currDate' ORDER BY CASE WHEN rotime2 THEN rotime2 WHEN rotime1 THEN rotime1 ELSE time); Is there a query sort that will work in this case? Is not the usual sort by last name, then sort by first name scenario! Thanks for any pointers.

[PHP] Search/Replace in entire database?
Hi everyone, I am in the middle of creating an editor where you can search and replace on an individual column in a single table then I came across something I need to be able to do but not sure how. Is it posible (And if so please how :-) to search an entire database and all tables within a database and do a find/replace on keywords without having to specify each table/column within that table? The people I am working for have made some big changes and one of them is changing the names of one of their products, but this product name appears EVERYWHERE in many tables and in lots of different column names, and it would save so much time if I could do a single query that would just search EVERYTHING within the database. Thanks for any advice you can give me. Regards Chris Payne -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
