I want to put my PHP program on Apache server(there are existing Perl program running there).
And I want to invoke those programs independently.
For example)
"http://my-address/existing-program" goes to Perl program,
on the other hand, "http://my-address/new-program" goes to PHP program.
I might need to modify "httpd.conf" but I am not sure how.
Any advise would be helpful.
Kind regards.
You could use mod_rewrite calls in your httpd.conf file to intercept specific URLs and make sure they're routed and handled accordingly.

OK. So, let's take PHP as an example.
I'm entering a URL in the browser, requesting a php script. (e.g. http://www.somedomain.com/index.php)
The browser sends that request to the appropriate server.
The server recognizes - by its extension (.php) - that's it's a PHP
file.
The PHP interpreter processes the file and outputs the results.
The server sends back the output.
Now, let's say we are dealing with a... home-made interpreter XYZ (with its binary,etc), dealing e.g. with .xyz files.
How should I go about that, so all the above things are valid for my XYZ interpreter?
How should I set this whole thing up, so that it works properly?
Hint : I'm not requesting help on how to write an interpreter, but on how to make it function the above way...
Your options are to either use an existing, standard interface and write your software to conform to it, or to write a new module for the server.
For the former, CGI is simple but inefficient while FastCGI is more modern but relatively complicated.
If you want to write a new module, then the specifics will depend on the server you are dealing with.
This totally depends on what web server you are using. However, if that is Apache, you should look into apxs for building and installing your own apache modules. Google will help you find online tutorials on apxs.
For adding a handler for a specific file ending, you should do something like this in your apache configuration (after your iterpreter/apache module is built):
AddHandler my_handler .end
I am writing a small web server, nothing fancy, I basically just want to be able to show some files. I would like to use PHP though, and im wondering if just putting the php code inside of the html will be fine, or if I need to actually use some type of PHP library?

I just downloaded that and I am going to use that to work off of. Basically I am writing a serverside game plugin that will allow game server owners to access a web control panel for their server. Some features would be possible with PHP so this is my goal. Any help would be appreciated, thanks!
The PHP won't serve itself. What happens in a web server like Apache is before the PHP is served to the user it is passed through a PHP parser. That PHP parser reads, understands and executes anything between (or even ) tags depending on configuration. The resultant output, usually still HTML, is served by the web server.
There are a number of ways to achieve this. Modules to process PHP have been written by Apache but you do not have to use these. PHP.exe on windows, installed from windows.php.net, will do this for you. Given a PHP file as an argument it will parse the PHP and spit the result back out on the standard output.
So, one option for you is to start PHP.exe from within your web server with a re-directed standard output to your program, and serve the result.
How to create a child process with re-directed IO: http://msdn.microsoft.com/en-us/library/ms682499%28VS.85%29.aspx however, you won't be writing the child process, that'll be PHP.exe
Caveat: I am not sure from a security / in production use perspective if this is the most secure approach, but it would work.
PHP needs to be processed by the PHP runtime. I'm assuming the case you're talking about is that you have a C++ server answering HTTP queries, and you want to write PHP code out with the HTML when you respond to clients.
I'm not aware of any general-purpose PHP library. The most straightforward solution is probably to use PHP as a CGI program.
Here's a link that might be useful for that: http://osdir.com/ml/php-general/2009-06/msg00473.html
This method is nice because you don't need to write the HTML+PHP out to a file first; you can stream it to PHP.
You need execute the PHP page to serve the page it generates.
The easiest thing for you to do would be to add CGI support to your webserver in some basic form. This is non-trivial, but not too difficult. Basically you need to pass PHP an environment and input, and retrieve the output.
Once you have CGI support you can just use any executable, including PHP, to generate webpages.
I'm trying to make a web app that will manage my Mercurial repositories for me.
I want it so that when I tell it to load repository X:
Connect to a MySQL server and make sure X exists.
Check if the user is allowed to access the repository.
If above is true, get the location of X from a mysql server.
Run a hgweb cgi script (python) containing the path of the repository.
Here is the problem, I want to: take the hgweb script, modify it, and run it.
But I do not want to: take the hgweb script, modify it, write it to a file and redirect there.
I am using Apache to run the httpd process.
Ryan Ballantyne has the right answer posted (I upvoted it). The backtick operator is the way to execute a shell script.
The simplest solution is probably to modify the hgweb script so that it doesn't "contain" the path to the repository, per se. Instead, pass it as a command-line argument. This means you don't have to worry about modifying and writing the hgweb script anywhere. All you'd have to do is:
//do stuff to get location of repository from MySQL into variable $x
//run shell script
$res = `python hgweb.py $x`;
You can run shell scripts from within PHP. There are various ways to do it, and complications with some hosts not providing the proper permissions, all of which are well-documented on php.net. That said, the simplest way is to simply enclose your command in backticks. So, to unzip a file, I could say:
`unzip /path/to/file`
SO, if your python script is such that it can be run from a command-line environment (or you could modify it so to run), this would seem to be the preferred method.
As far as you question, no, you're not likely to get php to execute a modified script without writing it somewhere, whether that's a file on the disk, a virtual file mapped to ram, or something similar.
It sounds like you might be trying to pound a railroad spike with a twig. If you're to the point where you're filtering access based on user permissions stored in MySQL, have you looked at existing HG solutions to make sure there isn't something more applicable than hgweb? It's really built for doing exactly one thing well, and this is a fair bit beyond it's normal realm.
I might suggest looking into apache's native authentication as a more convenient method for controlling access to repositories, then just serve the repo without modifying the script.
I'm not much of a programmer, PHP is where I'm comfortable. And sometimes I find that I need to do things, such as arrange files or rename files on a mass scale on my computer. And I think I could do this with PHP but I can't of course.
So I was curious, is there a way I could run PHP files as kind of exe files.
EDIT: Fairly important point, using Windows.
just use php.exe (put it in your path) and the name of the php file you want to execute
You should have a look at php gtk
It's not as bad as you put it. PHP may be a very good tool for string related stuff like parsing, renaming etc. Especially if you know PHP.
To use php as script you should add #!/path/to/php as first line and set execution permissions on unixoid systems. In windows you can simply assign the php file ending with your php cli exe so you can click on them or use the script with the "start" command in the windows shell. But make sure that you write your scripts in a way that it is sensible to the current working directory. It may be different to what you might expect sometimes.
to be able to execute php files with double click, just like normal programs, go to the command line, then type
ftype php_script "C:\path\to\php.exe" "%1"
assoc .php=php_script
Check out WinBinder
Sure, just add #!/path/to/php to the top of the file, add the code in tags, and run it as a shell script.
Works fine - the php binary you use is either the cgi one or the purpose built CLI version.

it would appear so, yes.
Download Wamp Server, install it. Once thats done, add the path to the php.exe to your PATH settings. You can do this by going to control panel->system->change settings->advanced->environment variables. Edit the PATH, add a ';' to the end of the line and then past the path to the php.exe. This is on Vista, it might be different on XP or Windows 7.
My path looks like this after: C:\Sun\SDK\jdk\bin;C:\wamp\bin\php\php5.3.0
Once thats done, you'll be able to execute a php file from the command line. You could create shortcuts too.

I used php for years as a scripting language before I even bothered to use it as a web programming language.
maybe php is not the right tool to doing this and it's about time to learn another language...use this chance to expand your programming horizion
See the .reg file in this gist, it makes it possible to use .php files exactly like .bat files, e.g. my_script.php foo bar baz
Don't forget to edit paths to suit your setup.
http://www.appcelerator.com/products/download/ Still use html & css as a desktop app and now has support for php.
PHP based web apps like Wordpress and Mediawiki I think uses php to setup and configure itself. Just give IIS proper read/write rights and you can make a simple web app that does massive renaming, etc.. PHP doesn't have to always be used for writing out html.
See ExeOutput for PHP. It has excellent customization and MAGNIFICENT features. Yet it is not an IDE or something. It compiles your PHP+HTML into fully-fledged EXEs.
I would like to add a preprocessor to HTML pages. Basically, I have a program that takes the name of an HTML file containing preprocessor instructions and outputs the contents of the file after preprocessing to stdout. This mechanism could change if it makes things easier. All I want to do is hook this into Apache so that all the files that my website serves get put through the preprocessor before going out to the browser. A solution that works with other HTTP servers than Apache would be preferred, but is not required.
If my understanding is correct, this is roughly what PHP does.
If it makes any difference, the preprocessor is written in Python.
If you have Apache and a "preprocessor" written in python, why not go for mod_python?
