Hi
how to make a script multi task based like this
?
for($i=1;$i=100;$i++)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,
'http://www.facebook.com/ajax/reqs.php?__a=1'
);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_USERAGENT, Opera/9.80 (Windows NT 5.1; U; tr)
Presto/2.6.22 Version/10.50);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_REFERER, http://www.facebook.com/reqs.php;);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
//curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_PROXY, 127.0.0.1:);
curl_exec($ch);
}
?
lets say this takes 1000 seconds and it doesnt focus to another curl
process
before it finish the previous one
is it possible to let the script focus another curl process without
wait
answer of the previous one
i hope if u could understand me ^^
This question has been asked several times over the last week, have a look
over the archive ;).
You need to be looking at something like process forking (

[PHP] PHP Application Structre
Greetings all, This question basically surrounds how you structure your PHP applications, whether it changes depending on what you're doing and which you'd favour. I have a feeling it'll come down to a question of personal taste, but on the off-chance there's a best practice I'll ask anyways. From what I've seen and used, there seem to be three distinct ways of going about it. 1) Using a 'core' class which has a request handler in it. All pages in the site are accessed through that one page, e.g. http://www.somesite.com/index.php?page=ViewUser http://www.somesite.com/index.php?page=ViewProduct This is one that I've personally used most after becoming familiar with a bulletin board system several years ago. It means that pages are easily created as all the template/session/database handling is done by the central class. 2) Using SE friendly URL's like: http://www.somesite.com/products/22012/cool-game/ http://www.somesite.com/products/22013/other-game/ This approach seems to be becoming more common on the sites I frequent, however by accounts I've read it seems to be more intensive on apache as it requires a mod-rewrite function. 3) Using different PHP files for each page: http://www.somesite.com/viewproduct.php?product= http://www.somesite.com/viewuser.php?user=... This would appear to be the least developer friendly option? Hopefully someone can shed some insight into which is the recommended approach and why. I've been building bigger and bigger sites so having a solid foundation is becoming more and more important. Thanks for any help/feedback, I hope I've been clear. Alex.
RE: [PHP] Still searching for a bugtracking system
Surely if it's not suitable for your situation, it's not the best? :) Mantis is what I'd recommend and believe has already been recommend to you. Runs using PHP and MySQL, it's flexible for public or private projects, multiple projects etc. I do agree with you that Bugzilla seems heavy, I know it has its supporters but I've always found it to be overkill for the projects I've worked on.

[PHP] Event Handling
Greetings all, I'm currently looking at building a web application, however I've run into an area of development I've not come across before. The web site in its basic form allows users to send cars from a point and then the car will arrive at another point. When the car is set on its way, the start time, travel duration and end time are all known and stored in a MySQL database, what I would like to happen is that an event is triggered on the server at the end time and then an e-mail is sent to the user. This should happen regardless of whether someone is browsing the website or not. I don't believe that I'll be able to solely use PHP, I have spent the afternoon trying to look at potential solutions but I have to admit I've drawn a blank. Google hasn't been helpful (64 pages so far), as any searches related to event handling bring up a load of JavaScript tutorials/help for 'onclick' events etc. I have searched through the PHP documentation and found libevent (http://www.php.net/manual/en/book.libevent.php ), I don't believe that is what I require (although in all honesty the lack of documentation on it means I'm quite in the dark as to its purpose). Another potential candidate I came across was a PHP/Java bridge (http://php-java-bridge.sourceforge.net/pjb/ ), whereby I could use the java virtual machine, register events with it and then callback PHP scripts, although this seems extremely long winded. I was hoping that someone might have some experience with this kind of issue and could point me in the right direction. I'm sure I've missed something right in front of me. Alex.
RE: [PHP] Event Handling
Thanks to all for your help on this, it's been very interesting for me to read. The system needs to check arrivals in real time (give or take a second or two), using a cron job every minute doesn't provide the real time checking I would like. However, when I then got to thinking about it, wouldn't this be an ideal solution? I create a PHP script that loops for 60 seconds, checking the database each second for new entries and processing them (meaning I get near real time monitoring), and then have that PHP script called by a cron job every minute. The reason I think that could be a good solution for me, is that if the PHP script crashed (for any reason), then at most it's 59 seconds before the system kicks in again and begins processing all the queued arrivals. If I coded a PHP script to loop infinitely processing things every second, it's possible I wouldn't notice a crash for a considerable amount of time. The proposed solution provides a good fail-safe, I think. Does that solution seem sensible? Or overkill? Thanks again for your help in this, it's quite novel for me. -Original Message- From: Ashley Sheridan [mailto:a...@ashleysheridan.co.uk] Sent: 15 March 2010 12:56 To: Midhun Girish Cc: Jochem Maas; David Hutto; php-general@lists.php.net; Alex Major Subject: Re: [PHP] Event Handling On Mon, 2010-03-15 at 18:28 +0530, Midhun Girish wrote: rene a page with an ajax script that kicks off the check-for-recent-events script on the server.. but that method is highly non reliable i dont think anyone will take that risk especially for an important web app cron or any equivalent which runs on the server must be used instead of that..

I agree. Even setting a cron on a local computer to call home to a server script would be preferable to Ajax calls.

[PHP] Question about Arrays
Hi List. I have a table, which contains 'setting' information for my website. The table has the following columns: setting_id, setting_name and setting_value. Now there are currently 30 settings stored in this table, however i am having trouble pulling values out on a 'as needed' basis. At the moment i have this select query: $settings_query = SELECT * FROM `robin_settings`; $settings_result = mysql_query($settings_query); And from that, i would like to pull individual results, for example... I have a setting which has a 'setting_id' of 4, a 'setting_name' called banner_on and a 'setting_value' of 1. How am i able to pull that information from the results i get? I know i could pull it by putting a WHERE clause on the SQL query, however that would mean having 30 select queries per page and i don't really fancy that! Thanks for any help!

[PHP] Calculations
Hi there list. Thanks for your help with my other questions. I was carrying on working through, and stumbled across a problem when trying to times something by the 'power' of something. By this I mean..in maths you can write 3 * (2 ^ 3), the answer to which would be 24. (as 2 ^ 3 = 8). The reason that I need this, is because I'm trying to double a variable x amount of times (x is set by another variable). For example my code is: $cost = $farm_cost * (2 ^ $farm_level); Any ideas how I would go about changing my calculation, as php dosn't seem to recognise ^ meaning 'to the power of'.

[PHP] If statement question
Hi list.
Basically, I'm still learning new things about php and I was wondering if
things inside an if statement get 'looked at' by a script if the condition
is false.
For example, would this mysql query get executed if $number = 0 ?
If ($number == 1) {
mysql_query($blah)
}
I know that's not really valid php, but hope it gets my point across. I was
just wondering from an optimisation perspective, as I don't want sql
commands being executed when they don't need to be (unnecessary server
usage).
Thanks in advance for your responses.
Alex.

[PHP] An annoying session problem
Hi there. I'm working my way through a new script, but I've stumbled into a problem. Some data that I've set into a session, won't be processed by part of my php code, but then later on in the page I can get the session value to output. Also, just so that its clear, the mysql code is correct (I can put it into phpmyadmin and get results from it. Heres the code (this code is 'included' in another page, where the session originates and session_start(); is set.) ?php // Lets see how much the person has at the moment. $current_resource_query = SELECT food, wood, stone, gold, population FROM game_resources WHERE user_id = '.$_SESSION['user_id'].'; $current_resource_result = mysql_query($current_resource_query); $current_resource = mysql_fetch_assoc($current_resource_result); ? table width=100% cellspacing=1 cellpadding=1 tr td colspan=5?php $userid ? ?php $_SESSION['username'] ?/td /tr tr td width=20%Food: ?php $current_resource['food'] ?/td td width=20%Wood: ?php $current_resource['wood'] ?/td td width=20%Stone: ?php $current_resource['stone'] ?/td td width=20%Gold: ?php $current_resource['gold'] ?/td td width=20%Session id is: ?php echo ''.$_SESSION['user_id'].'' ?/td /tr /table The error may not necessarily be to do with the session, but non of the $current_resources are showing.

Hmpf, well I feel like a real tit now. I tried all the posted suggestions, and still couldn't figure out why it wasn't working. I went back to re-code the whole page from scratch, started off with include 'connection.php', then it hit me...i hadn't included the connection file in the parent file to the include, so it wasn't (and couldn't) connect to the database. I put the connection file into the parent file, and now its working! Sorry to have taken so much time up with such a silly little thing. Regards, Alex.

[PHP] Using PHP/HTML effectivly
Hi List, I've been (very slowly) working my way through some basic php, and putting it into my html site. However recently (after trying things out such as cookies or redirects where they have to be set before any page output) I've found that the combination or certainly the way that I'm using php and html together dosn't seem to go too well. I have a question to you experienced PHP developers, how do you mix the html/php together. When I've looked at things like the PHPBB forums, and gone through files they will have absolutly no HTML, just php code. I'm not sure how they manage their page styling, if anyone could explain this too me. At the moment I have things such as table ... ?php Some php code making a page header ? /table table ... ?php Content... ? /table I'm sure that I'm not doing it the best possible way, so if anyone has any tips for me. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thankyou everyone who responded to my original message. All of your ideas
have showed me the various ways of doing it, however I believe that the idea
from Jons message is best suited to my needs. I realise the logic behind it,
its put together some knowledge I have already so I think I'll use it for
the time being.
Thankyou for taking the time to respond to my message.

This is my opinion on the matter...
From experience, I would say that mixing PHP and HTML together in a
complicated page can often get very ugly. I prefer to separate out
presentation and code into separate layers as much as possible.
I have most often used template systems such as Smarty (smarty.php.net)
for that. I use Smarty for work - I find it quite nice. It allows you to
separate your code from your presentation very effectively. It's easy to
use, and provides things like caching for performance.
However, I came to the realization recently that PHP itself is
essentially a very feature rich template system (nevermind the fact that
it's a well defined language. ;-)
By splitting up my most recent project into includes, templates, and
pages, I get a solution to the problem in pure PHP. In the end, code
looks like code, and HTML looks (almost) like HTML and both are
readable. (Same result as what Smarty gives you, without needing Smarty.)
Most pages look something like:
?php
include('include/data_functions.php');
if ($condition) {
$title = 'Here is Some Data!';
$data = getSomeData($var1,$var2);
} else {
$title = 'Here is the Other Data!';
$data = getOtherData($var1,$var2);
}
include('template/page.php');
?
And most templates look something like:
?php include('template/head.php'); ?
h1?= $title ?/h1
...
table
?php foreach ($data as $item) { ?
tr
td?= $item['part1'] ?/td
td?= $item['part2'] ?/td
/tr
?php } /* END foreach ($data as $item) */ ?
/table
...
pThanks for your interest in my data!/p
?php include('template/foot.php'); ?
