Forking A PHP Process Into The Background In A Web Server Environment
I have installed the PCNTL functions[1] on my PHP enabled webserver
in the interest of being able to fork a process into the background so I
can do some heavy processing but return control of the browser back to the
user rather quickly.
However, after mucking about with PCNTL for a while and not getting the
results I expected, I finally stumbled across this line in the opening
parragraph on PCNTL functions on PHP.net:
"Process Control should not be enabled within a webserver environment and
unexpected results may happen if any Process Control functions are used
within a webserver environment."
Seems like they should bold and highlight in red that line, but I digress.
In any case, can anyone suggest a way to fork a process off to unload a
large amount of processing and return control of the web browser to the
user? All the examples and whatnot I have found assume a CLI version of
PHP. I want to do this on the web server!
[1]I am running Apache2/PHP4.3 on RHEL 4. I downloaded the RPM for PCNTL

Background Process
I would like to create a script that acts like a background process. Basically once every hour, it will access a website, gather data from it, and write that data to a file on a remote server. The PHP code would be running on this same server. Is this type of non user activated, constantly running code possible?

Exec Background Process
I want have PHP call another process (another PHP script at the moment but it may end up being a binary) in the background and not wait for process to complete, but rather instantly jump the the next line of code. I've tried things like: exec("./script.php &"); // script.php has executable permissions set exec("at -f ./script.php now"); // and #!/usr/bin/php at the top of the code Neither seem to work. They both execute script.php, but both hang around until script.php has completed.

XP Exec Background Process
I was trying to exec a background process on XP using PHP CLI, but could not get it to work. Suppose the command I want to spawn off is "cmd". On *nix, it is as easy as putting ampersand "&" at the end of the command. I tried the following on XP without working. exec("cmd"); exec("cmd >NUL"); exec("cmd /c cmd"); exec("start /b cmd"); I tried many combination, but on each one, PHP waits for cmd to exit before continuing. Doing this in Windows script host (cscript) is simple: Set objShell = CreateObject("WScript.Shell") objShell.Run "cmd", 0, False The "False" parameter causes the Run method to continue immediately without waiting for the command to finish. So I could make my PHP file exec a VBS file that does the actual background execution of my command. PHP exec documentation says it will not wait if output of the command is redirected somewhere, but this didn't seem to work for me. If anyone has experience in doing something like this on Windows XP SP2,

Background Process/multithreading In PHP?
I use PHP for a user login application and it works fine. The problem is that another process should start up as soon as the user logs in and should keep on displaying different popup messages every 5 minutes. Is there a way I can implement this using PHP? Basically the idea is to get a background process running, thats it.

Development Environment
I have a little experience in PHP programming (created some simple scripts, database driven sites, customized simple xoops modules) but this was just unprofessional piece of work. My favorite php editor was Notepad…. But now I'm seriously going to become professional php programmer. I selected PHP instead of APS because it's open source and also it's just real language for good freelancer :-). So I'm wondering: what development environment do you use? I heard a lot of good things on this forum about php editor script…. But it's not environment as I understand – just a way to edit script placed on the server…. Also I thought about Zend software. There is a lot of software for web developers made up by Zend. So does Zend studio worth it? Will it work after this on LAMP server? Will I get just clear php code that can be run on every server or I will be forced to use server with Zend engine…… Has Zend studio built-in MySQL database?

Running PHP 4 And PHP 5 Together In Vhost Environment.
We are running PHP 4 right now on our servers and would like to give people the option of experimenting/using PHP 5 if they desire. Our system are RedHat Linux running Apache 1.3.x -- would have really like to run both PHP 4 and PHP 5 together as modules, but that seems to be impossible due to name conflicts. The only other solutions we saw were to run PHP5 as CGI (which had drawbacks), or try running a proxy server (below). Our requirements were that it had to support multiple virtual hosts, allow people to try out PHP5 by just giving a file a .php5 extension, support putting an entire site on php5 and also work regardless of relative/absolute URLs that might be used in their code. Here is the solution we came up with, any feedback is welcome: We decided to run a 'back' server built with PHP 5 and responding at a unique IP address. The vhost info on this server would be almost identical to the main servers, except for their virtual host names,e.g. Main Server - www.alpha.com Back Server - php5.alpha.com The php5.alpha.com is also added to their dns info and resolves to the IP address of the 'back' server. All the vhosts on that server are NameVirtualHosts. The DocumentRoot, etc.. would be identical. Our main servers would have a Reverse Proxy setup so that any request for a file ending in .php5 would be sent to the Back server for processing. (If someone wanted their whole site to switch to PHP 5 we would just alter the rewrite conditions to accept all php files in their vhost block). If they wanted to experiment with seeing what their site looks like under php 5, they could go to http://php5.alpha.com/ -- IF they used relative URL's in all their code, they would be consistent on 5. On our main web servers (we do virtual hosting), we added the following in the main area of the config file: ======================== <IfModule mod_proxy.c> RewriteEngine On # this condition should only match on files ending in php5 (any case) RewriteCond %{REQUEST_FILENAME} ^(.*).php5$ [NC] # this condition picks apart the host part of the URL, we need # to change www.alpha.com -> php5.alpha.com RewriteCond %{HTTP_HOST} ^www.(.*)$ [NC] # this rule modifies the request and submits as proxy RewriteRule (.*)(.php5) http://php5.%1/$1$2 [P,NC] ProxyRequests Off </IfModule> ===================== In each of the vhost blocks on the main server we allow them to inherit the rule with the following. We do have some concerns about performance and using mod_rewrite to scan all requests, but we will just turn on 'inherit' for the domains that want to test.

Multi User Environment.
I am developing a CMS and I would like to be able when a user is editing a page to inform any other user that the page is being edited by User X . Ofcourse that's not so difficult if you set a flag in the database for example that the current document is being edited, and remove the flag when the user saves the document and exits. BUT what happens if user exits the editing page without folowing any link or submit button that I can control. What happens if his computer restarts/crashes or he kills the browser. Database will have the document flaged as being edited by User X. Do you know any good way of avoiding that problem or if you don't already know, can you think of something similar ?

Development Environment (w/ Source Control And Versioning)
Right now our development environment consists of a single 1U white box (well, black actually, but you get the idea) redhat fc4 server running PHP 5, MySQL 5, and Apache 2. We've got 3 development workstations, all running windows (Dreamweaver, Photoshop CS2 and EMS MySQL Manager). We're desperately trying to come up with some form of versioning and source code control. I'd like to use SVN, but I can't come up with a workable solution for implementing it. I've come up with 3 ways to do this, none of which are very appealing: 1.) I could just setup a project in SVN, check it out into the webroot on the development server, we could all work on it there (and avoid crushing one another's documents with WebDAV + Dreamweaver), then, check it back in on a regular basis. Unfortunately, that means that we've got 3 people working against a single "checkout" of the source code. 2.) We could setup apache/php on each developer's workstation, we could checkout the code and run it on our own machines. Drawbacks include the overhead of the webserver and PHP and the incompatibilities between the development server and our workstations. 3.) I could setup seperate web root's for each developer (along with its own hostname), we could each checkout our own copy, work in our own web root, and check back in when we're finished. Is there some other cleaner solution to this? I'm sure most people developing in PHP are using SVN (or even CVS) for source control - so how do you setup your development environment(s)?
