PHP Processes
I have a cronjob triggering a php script that takes several minutes to accomplish. I need to prevent multiple triggering by the cronjob mulfunctioning. So I would like a clean way to know how many instances of a certain php are currently working on the server. is there a server variable for that? if not, how do I know (via php) how many concurrent accesses are there to a certain php page? for example in mysql (the "SHOW PROCESSLIST" command), but I need a similar function for the php page iself.

Listing Processes In PHP
Using PHP, is it possible to return and display a list of currently running processes on the client's machine? In fact, is it possible to run a system command on a client's machine?

Automated Processes
Customers post 'projects' to my site. These 'projects' are closed after 10 days. I could run a script on the default.php page that detects this, but it seems a waste of resources to run it everytime someone visits the site. Is there a way around this, for example the first visitor to the site in any, say, 3 hour period, runs the script & switches the most recently outdated projects from open to closed?

Max Number Of Processes
how can i determine what the maximum number of processes i should open with popen (or proc_open) is? i assume it'd depend on the hardware of the computer in question, but if that were teh case, then is there a way to get info. about it, and some general method to determine a good number of processes to open from that info?

Stranded PHP Processes And ProcessExplorer
Does anyone know what it means if I see PHP processes in the process tree at the base level, instead of under the IIS worker process? I do nothing but web serving off of the box. These processes that are not under the IIS worker process seem to be stranded/hung. They are never cleaned up by any garbage collection and I have to kill them manually. They also always have a fairly low memory usage, potentially indicating that they fail before loading completely. Could it be that the execution of the process fails early enough that ProcessExplorer doesn't see them as being executed by IIS?

Handling Long Processes
I am building web app, that will run a long processs (image processing) that can porbably take 15-30 minutes to complete) in respond to a user request (the user clicks a "process" button on a php web form). The ideal situation that I see is once the user's request was recevied, a reply that says "you request is being processed. we will send you email once finished", will be sent to the user, while the other process will take place. When it's finished, a callback function will be called that sends email to the user notifying him the process outcome. What are the options to implement that? multithreading?

Shared Memory Between 2 Processes?
I have two running php processes (they have infinite loops) and I need them to pass some data to eachother. Writing and reading shared memory in one process works just fine but when I try to save var in process1 and read in process2 I get error: "Variable key 555 doesn't exist". What I'm doing wrong? //PROCESS 1 (saving var) $key = 'My Key' $value = 'My Value' $app = 'lovelyapp' $key = $key . 'a' $segment_key = abs(crc32($app . $key)); $segment_size = 1024; $segment_perms = 0600; $shm_id = shm_attach($segment_key, $segment_size, $segment_perms); shm_put_var($shm_id, 555, $value); shm_detach($shm_id); // PROCESS 2 (reading var) $key = 'My Key' $app = 'lovelyapp' $key = $key . 'a' $segment_key = abs(crc32($app . $key)); $segment_size = 1024; $segment_perms = 0600; $shm_id = shm_attach($segment_key, $segment_size, $segment_perms); $value = shm_get_var($shm_id, 555); shm_detach($shm_id);

Forking Multiple Processes At A Time
i have a php script that needs to execute an external php script (call this script 2) when the user clicks a link, however I don't want the user to have to wait until script 2 finishes executing before he sees the output of script one... i know I can use the exec() command to do this, and use the & to run the command in the background.... but say i want to run 100 instances of script 2 when the user clicks the link (with different arguments)... i dont want to have all 100 processes running at the same time... what I would like to do is run 10 or so at once, and once those 10 are completed, run another 10...

Large Data Transfer Between 2 Processes
fist the context: I have a web server which query a mySql database. but as the number of parralel queries increase, the server slows down too much. I got 2 ideas, one of which is to run N deamons which effectively execute requests. the PHP uses message queuing(1) to queue queries request to the daemons. but the answer may be quite large, larger than messages the message queueing service can handle. I thought to open back a communication link between the current daemon and the waiting PHP to tranfer/process the result, using the message queueing service to send back info regarding the opened link. I thought to open a pipe between the current daemon and the PHP. is this possible? and if so, how? if not, is an IP link to localhost be as fast as a pipe?

Keeping Users Informed In Lengthy PHP Processes
Often PHP processes take a long time, such as wildcard searching a PostgreSQL database, or generating thumbnails. The PHP host page does not display until the script is complete, so you can not effectively use code such as echo "Converting file ".$Infile; exec(convert $Infile $O8utfile); for realtime feedback to the user. How have others implemented a "progress meter" in PHP processes , one thought I had was to use Javascript redirection to call a PHP page with differing parameters each time .

Sending Signals To Processes As A Different User Than Owner Using Php
i know, it seems more to be a problem according to unix but i got it while developing software with php: i have 2 different users on a hp-ux machine that execute php scripts. they are both in the same group. these php scripts start background processes, i can communicate with using signals (sending with posix_kill, starting background processes via pcntl_fork). so i got severel background processes owned by my 2 users. the problem is i want to send signals as one of my 2 users to all my php background processes no matter who of my 2 users is the owner. is it possible other than using external tools like sudo? i'm using: PHP 4.3.4 (cgi) (built: Aug 18 2004 15:37:46) Copyright (c) 1997-2003 The PHP Group Zend Engine v1.3.0, Copyright (c) 1998-2003 Zend Technologies compiled with: ../configure' '--prefix=/usr/local/php-cgi-saprfc' '--enable-calendar' '--enable-filepro' '--with-gd' '--with-jpeg-dir=/usr/local' '--with-zlib-dir=/usr/local' '--without-mysql' '--enable-sysvsem' '--enable-sysvshm' '--with-pgsql=/usr/local/pgsql' '--enable-trans-sid' '--with-cpdflib=/usr/local' '--enable-sockets' '--with-ncurses=/usr/local' '--disable-shared' '--with-tsrm-pthreads' '--with-saprfc=/usr/local/rfcsdk' '--enable-pcntl

Max_execution_time Ignored, Multiple Apache Processes Spawned
I have an app that is going berzerk on its own; without any code or environmental changes of any kind, for some bizarre reason it will randomly just hang, spawn multiple Apache processes and completely ignore max_execution_time, literally running infinitely. Using PHP 5.2.0, Apache 1.3 and Win XP Is this normal "bizarre" behavior that can occur within this setup; if so, what workarounds have you found to combat this, other than the obvious (try to debug and fix code)?

Limiting The Number Of Spawned MySQL Child Processes
Need to know if there is any way to limit the number of spawned MySQL child processes in linux ? I have done my research at http://www.mysql.com and have not been able to find my answer. Have also looked at the source code (what i can understand of it). Using MySQL v.4.0.25-max. Using an older system and the 14 childern are just bogging the system down. I am the only one with access to the server so 14 childern is overkill.

Checkboxes - Loop That Takes The Values And Processes And Writes The Changes To The Database.
I generate a form page from my MySQL database. let's say the table structure is: Table A > ID, title, active the number of rows generated by the query is dynamic. If a field's value is 1, then the form output appears as <input type=checkbox name=$ID checked> $title and if not <input type=checkbox name=$ID> $title At the bottom of the form there is a submit button. The visitor can check/uncheck rows and then submit the form. I need to write a loop (possibly foreach) that takes the values and processes them and writes the changes to the database.

In Background
Here's my situation. I'm creating a website (basically a store) and in the admin section users will want to download zip files of images or products added in the last 7 days, last 2 weeks and the last month. I have scripted a cron to run every 24 hours to zip all the images and this process takes over 1 minute (there's over 6,000 images!!) and the size of this is 250MB. This has now taken me to my quota on my webspace of 500MB (including all the individual images) I have decided the only way to do this is dynamically create the zip when the user requests it. As PHP times out after 30 seconds it needs to do it's stuff in the background and display a message saying something like' We'll email you with the zip file in 5 minutes or so'.

Run In The Background?
I have a script on my website that takes a long time to run, and it's slowing down my pages. Theres nothing I can do about the wait time on the file. Is there a way to use include or fopen or anything along those lines, to have it execute my file in the background; without having the file that's executing it waiting for it to finish its thing? Or to have the expected output redirected to another file (as mentioned in http://ca3.php.net/manual/en/function.exec.php)?

Running Php In The Background
I am trying to run a php executable (GTK) from a browser... now exec() does the job, but the browser hangs waiting for the .exe I have just called to finish, I assume so it can 'report back' to exec(), any ideas how I can get around this ? - I have tried backticks,passthru,system,exec - all with the same results, i.e. they all expect a returned value and sit around waiting for it. This is a windows app so /dev/null wont help & it is not a CGI with output I can dump anyway.

Run A Php In The Background Using Http
i have a script (script1) which needs to call another script (script2). It should not wait for the answer, so script2 should run in the background. I really need to call the php script using: http://urlof myscript/script2.php I don't want to use it as a cgi and use CLI. I did a test with fsockopen and curl and a timeout of 10 seconds and call http://urlof myscript/script1.php from my browser: Script1 stops after 10 seconds => OK Script2 has been called by script1 and continue to run in the background =>OK After 60 seconds Script2 is killed by php!! => KO :( The script is working fine if i call http://urlof myscript/script2.php from my browser. It needs around 120 seconds to finish. Why is it stopping after 60 seconds when I use fsockopen and call it from script1? Here is the script in SCRIPT1: $fp = fsockopen("$host", 80, $errno, $errstr, 30); stream_set_timeout($fp,10); if (!$fp) { echo "$errstr ($errno)<br /> "; } else { $out = "GET $path HTTP/1.1 "; $out .= "Host: $host "; $out .= "Connection: Close "; fwrite($fp, $out); $status = socket_get_status($fp); while (!feof($fp) && !$status['timed_out']) { echo fgets($fp, 128); $status = socket_get_status($fp); } fclose($fp); } I have added this in SCRIPT2: ignore_user_abort(FALSE); // becareful, FALSE really means it should ignore user abort !!! set_time_limit (120); ini_set("max_input_time",120); ini_set("max_execution_time",120); Do you have any idea?

A Way To Get Current Background?
I have several websites running on a global script. Some pages, the backgrounds black, other, white. Sometimes people have the taste of posting black font on a black background, or white font on a white background. What I wanted is to know if theres a way to 'check' the current background color? Because I can then add in the script to 'change' any incorrect colors before posting. I'm not sure if theres a way for PHP to tap into CSS and check, but it would be alot easier to change the global script since its *Checking* for the background color rather then me do it per site and change it manually.

Background Redirection
I need to create a redirection from a php page to another, without having a web browser opened. Imagine that you make a php starting via command line or cron job, then your php is running in background and no web browser is open on it. How can this php (from the background, with no web browser opened) call (trigger) another php? please note that I'm not talking about include. I need that the background php gives control to ANOTHER php url . per what I tested the php 'header' command does not work and obviously also any javascript redirection cannot work because there is no web browser opened. so, finally, how can that php running in background call another php url?

Background Tasks
I'm using some weather rss feeds in a web site. The feeds are updated once every hour and cached in a local file. My problem is that every time the weather report is updating I get a long wait (not that long.. 2 or 3 secs) before the page is displayed. This happens becauses the teplate engine that parses the page is waiting for the weather section to be parsed and cached. Is there a ay I can start the weather parsing as a background thread and return immediatly to the template engine to continue to parse the page? And if so How?

Run PHP-Script In Background
I am using php 5.0.4 under IIS 6 under Windows Server 2003 and want to run a php-script as a separate process. This schript dies not have any output. I tried several variants without success: exec("c/php5/php.exe path/to/script parameters &") will run the schript but will wait until the schript finished processing. exec("c/php5/php.exe path/to/script parameters > null &") gives me the error message "The specified CGI application exceeded the allowed time for processing. The server has deleted the process." Dealing with other variants of php cli procesors like php-win.exe gave the same result. Also trying to use the start command did not help.

Depending on how many accounts are affected it may take a little while before the pages returns back to the original one with the form. I was thinking that perhaps I could take the email script and put it into a separate page and trigger it at the same time.

Is it a setting in HTML that determines this or does it have to be done through php?
