Want To Spawn Process From Windows PHP
I wanted to write some code purely on Linux, but unfortunately the document scanner drivers are non-existent for the high-end commercial document scanners. So, I had to port my Linux PHP project to Windows PHP (WAMP). There, I found a scanning tool (Kodak Image Scan - imgscan.ocx) that I can put on a VB form, tell it to scan some documents into a TIF file, and then shut down. I can run this VB app at command line just fine, but when I run it from either a popen(), system(), or exec() call, it won't detach from the PHP page. Instead, it just sits there. I can see the VB exe I made is being loaded properly in RAM, but unfortunately it sticks and won't unload on its own, nor will it tell the scanner to engage. I have to kill the VB exe and then the PHP page continues. What's the way to spawn a detached process from PHP on Windows?

Calling PHP From A Windows Process
I'm calling PHP from a windowsprocess in a simple Webserver application. I'm using the createprocess Windows API command.... C:PhpPHP Filename.php In this file I will open a TCP/IP connection to my SQL-server. When I do so, I always get the following error mysql_connect(): Can't create TCP/IP socket (10106) No I start a command shell and I call the same... C:PhpPHP Filename.php This will work without any error!! Same effect I get from all TCP/IP Actions (FTP etc....) Can somebody help me. Is it a PHP Setting, a server variable or a WindowsXP Access right problem?

How Does PHP5 Process POST Data In Creating $_POST Array?
I need to save a wav file that is HTTP POSTed to a php page. What does PHP5 do automatically to a POSTed variable when it puts it in the $_POST[] superglobal array? I haven't been able to find any info on this.... I have a script that does what I want in PERL, but I need to do it in PHP. I think the PERL does something magic when it does this: #### PERL CODE #### read ( STDIN, $buffer, $ENV { 'CONTENT_LENGTH' } ); @pairs = split ( /&/, $buffer ); foreach $pair ( @pairs ) { ($name, $value) = split(/=/, $pair); $value =~ tr/+/ /; $value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg; $FORM { $name } = $value; } #### END PERL CODE ####

Simulating Post
if theres something similar in php to libwww in perl $f = HTML::Form->parse("http://www.example.com/index.html"); $action = "http://login.example.com/login.cgi?etcetcetc="; $f->action($action); $f->push_input("text",{email=>"email@email.com"}); $f->push_input("password",{password=>"pw"}); $f->click so i can login via a simulated post from php rather than through a form.

PHP Fork
I would like to have a fork in my PHP code - the coding will branch with 2 possible options to execute (2 possible web contents to show). Which one is executed will depend on a certain changeble ratio factor. So, for instance, if the ratio is 3:7: if the PHP code is called 10 times - 3 times option 1 will be run. 7 times option 2 will be run. how can I go about coding this. I really haven't got a clue how to implement this ratio (probability) control.

Max_execution_time And Fork
I use recursive readdir as the engine for a numerous file processing routines, including generating thumbnails, using getimagesize imagecreatetruecolor and imagejpeg, etc. where each resize operation involves instantiating a new resizer class instance. .....but my (shared host) website is large, so I run past max_execution_time if I try to make all thumbnails at once, from the top of my document_root. My virtual file system includes a php.ini which I can edit, but bumping max_execution-time (although the file saves) seems to have no effect, and I do not have permission to run /usr/sbin/apachectl restart Perhaps the php.ini change will start to work the next time the server reboots. In the mean time, is there some way to fork a new process, for instantiating the resizer? I could try to use exec to run command line php. But there must be a more elegant way to do this. I'd use perl and imagemagick, but my shared host server doesn't have the right perl libs installed, and that's another can of worms.

'fork' A Session
I am working on a webbased application (not a website) and from a page a new instance of the browser is started (using javascript) offering a different set of functionalities. What I want is that each new instance of the browser continues with its own set of sessionvariables, as two different sessions. Is that possible? I use the following javascript function: window.open('code.php?submit=new&id=1,'status=no') I use session_start() at the beginning of every page, i also considered using session_regenerate_id in various ways but this didn't have the desired effect.

Simulating Object Upcasting To An Interface In PHP 4
In Java one is supposed to upcast an object to its interface whenever appropriate: MyInterface customers = new MySpecificClass(); The idea is that if later one wants to change the specific implementation one only has to change a few lines, possibly just the one line above. Thus the code becomes more flexible. Is it right to say that there is no way to do this in PHP? I've taken to simulating the same by using one object as a mask that sets and then uses another object: myMaskObj = new MaskDatabase(); myMaskObj->setDbObj("DatabaseObject"); myMaskObj->query("SELECT * FROM content WHERE type='comments'"); MaskDatabase has a method called "query" which simply passes the query along to DatabaseObject which also has a method called query.

Simulating Include Statement With Html Only
Is there a way to simulate the php include() statement in html that does not require php but only html? I have a bunch of html files that all have the exact same navagation coded into each file. I want to move the navagation code to one file and then include it into the html as the page is requested. I have done this sucessfully in the past by inserting an include() statement inside php tags and running the html page through the php interpeter. Problem is that in this case I don't think that the host will let me run those html files through the php interpeter. I have looked around in html at some of the tags that are not sure as much and as yet havn't found a way.

Process ID

Getting Your Own Process ID
I am doing some work where I want to do locking, and prevent scripts from running in parallel. I see that I could use the semaphore mechanism, but I'd like for my code to be portable, and that extension is not enabled in many places. I need some way for a process to uniquely identify itself. It can then look at the storage container (flat file, DB, whatever is appropriate in context), check to see if the requested semaphore is available, and if it is, acquire it and then mark itself as the owner. It can then check that it did in fact get ownership (as opposed to another process which attempted to acquire it at the exact same moment) before proceeding. Code:

Process This Form
I want to have a form which has several rows for example: username1 firstname1 surname1 username2 firstname2 surname2 username3 firstname3 surname3 username4 firstname4 surname4 What I want to do is when this data is typed into the form to save it in a MYSQL db. The problem isn't with the saving, it's with the form itself. What is the best way to process this? I can't really name the various fields "username1" and "username2" because I would then need to replicate these as variables and this form generated could have an number of rows so hard coding the form field names with numbers makes it hard. Is there any way I can do this?? How have other people tackled this sort of thing in the past?

PHP Load Process
I've tried searching around for information on how PHP parses and renders itself. Basically, I'm writing a bunch of scripts that rely on a core file. The core itself is quite large (around 20k), but the scripts that reference it don't often utilise the entire contents of the core. Inside the core are functions that are never called *inside* the core, and a bunch of constants and globals that I call from the referencing scripts. So I guess in a nutshell, I want to know if when I call require, does PHP read the *entire* file? Or does it only read the bits it needs? I realise that last sentence makes me sound like I have trouble putting legos together, but I would just like to know how PHP goes about it duty.

I already know the php commands to kill a process and also to list the running processes, but i was wondering if it was possible to get the php code to store the PID of the program upon starting so that when the "kill" button is pressed, it reads the string from the database/text file etc. and kills that process only.
