running php

[dcbc]

hello
i am trying to learn php. i am using ultimate ubuntu 1.4. i think it has apache installed.

Now i am suppose to create a file hello.php and put it in my web server's root directory (DOCUMENT_ROOT).

i don't know where is this "web server's root directory"

[darkrose0510]

The server's document root is in /var/www

If you're not using the server on the web, just locally for testing, then you should be safe to open a terminal and:

sudo chmod 777 /var/www/

so you can read and write to that directory. Go to http://localhost/hello.php in your browser to view your page.

thank you darkrose0510.

Now when i type
http://localhost/hello.php
in my browser (Mozilla Fireforx)
instead of showing my page
it asks whether to save this file or open it (with which
software)?

i am not using the server on the web.it is just for locally testing so that i could learn php.

Note that, depending on the configuration of the server, this might have some serious security implications. It doesn't matter if you just enable it localy for testing purposes. But even if you just use it locally, you need to know that, unless you forbid the access via a firewall or something it will be open to the whole world, and to every hacker or attacker under the sun.

Probably, your server is not configured to use php properly, so, it acts just like when you try to open any other file that the browser can't understand.

You need to check your distro's docs, it surely must have instructions on how to enable php for your particular web server.

I mean the documentation for your distro.

On a quick search, I found this:
https://help.ubuntu.com/community/ApacheMySQLPHP

There's a section called "Installing PHP5", on it, you can read this:

Troubleshooting

Does your browser ask if you want to download the php file instead of displaying it? If Apache is not actually parsing the php after you restarted it, install libapache2-mod-php5. It is installed when you install the php5 package, but may have been removed inadvertently by packages which need to run a different version of php. You may also need to actually enable it, by doing sudo a2enmod php5 followed by sudo /etc/init.d/apache2 restart. Be sure to clear your browser's cache before testing your site again.

I hope that helps.
