Setting class paths

[Xu Wei Jie]

I wonder for PHP, are we able to set class paths so we can call a php script from a written library without specifying the full path to the script?

[wildteen88]

The only way you can do this is place all your classes within a dedicated folder. You'll then want to add this folder to PHP's include_path setting. So when

ever you want to include a class you'd do

 

include 'your_class.php';

 

rather than

include 'path/to/your_class.php';

check out this:

I think both of you are mistaken. I wanted to put all my written scripts into a library(folder) and set the classpath to them so I would not need to type out long paths to execute them. ( for example the php command, once it is installed and having its class path set, you can invoke it from any directory). I do want to achieve that effect.

 

i.e php x.php

 

x.php is stored in a library I created. i wish to invoke it from any directory, is it possible?

Your question has nothing to do with php itself. Its your shell that parses the command

 

php x.php

 

And no, x.php will need to be within the current directory or you will need to give your shell the complete path to the file.

[trq]

What you can do however is place a shebang on the first line of your scripts.

 

#!/usr/bin/php

 

Then place x.php in your system path and simply execute....

 

x.php

 

from your shell.

[rhodesa]

as thorpe said, this is OS related...not PHP.

 

What OS is this for?

[Xu Wei Jie]

I am currently using windows. However, I wish to be independent from platform

[trq]

Your going to struggle there. Windows won't recognise a shabang and only has a very limited shell (if you could even call it that).

 

If this is the only entry point to your application you could likey write a wrapper around it specific to the OS its running on. But again, this isn't a php question.

[rhodesa]

On Windows, you will need to edit the System Environmental variables to include the folder with your PHP executable as well as your 'library'

 

Unix based platforms are the same concept, but a little different in execution

 

edit: actually...since the path to the script would be an argument to the PHP executable, this won't work...hum....

[Xu Wei Jie]

Yah I guess since x.php is parsed to the php cli.

It is hard to come up with a solution such that x.php can be invoked by itself and a shebang won't work with different platforms.

[Xu Wei Jie]

I found an alternative for windows. However, I don't know how a shebang works. Can anyone guide me on how to execute x.php. This script is not on a server.

 

x.php

#!C:\php\php.exe -q

<?php echo "Hello world of PHP CLI!"; ?>

 

[Xu Wei Jie]

Sorry guys, this is a noob question.

Can anyone teach me how to use a shebang on both windows and unix?

[Silverado_NL]

Windows won't recognise a shabang and only has a very limited shell

like he said, shebang doesnt work with windows systems.

[Xu Wei Jie]

Actually, I have googled to this site and it says it is possible on windows. Probably I am mistaken?

 

http://www.php-cli.com/

[Silverado_NL]

well the site states it might work with CLI,

but i would take thorpe's word over a website with that many spelling errors and just make a wrapper:P

Edit:  I think I may have entirely misunderstood this thread....  If so, just ignore this.

 

 

 

You can set the handler for .php files, just as the handler is set for .bat, .jpg... so on.

 

 

All you have to do is associate the .php file extension with your PHP binary.

 

 

Don't remember the exact steps to do it through the registry, but you should be able to do it through the Open With menu when right clicking.

 

 

Then, after .php is associated with it, you should be able to just do:

 

 

file.php in the command line.

[Xu Wei Jie]

so if we use a shebang on unix, we just type the name of the script and it will execute?

[corbin]

Yes.  That's the point of a shebang line.
