I have installed debian etch and apache

later downloaded and installed mysql and it is working

PHP is also working

but when i write code to connect to the mysql
i.e $conn=mysql_connect("localhost","root","")

Fatal error: Call to undefined function: mysql_connect() in /var/www/apache2-default/sal.php on line 8

where is the problem?

is it with apache? mysql? PHP?

is is required to apache get compiled after the installation of mysql
to support mysql libraries?

the mysql is a binary (tgz) version (not source code) which i installed

Have you installed the php-mysql package? Try running:
as root at the command line.

I'm not a debian user so if that doesn't work try agt-get instead of aptitude.

Cheers!

I don't like to lean towards a particular distro

that is why i installed downloaded mysql from tar binary though it is possible to install it from the installation cd. I would like to do things in a standardised way - i.e The solutions should be applicable to every distro (for example getting packages in tar form is acceptable to all distros also compiling them is acceptable to all systems)

How ever I understand that for my problem, the package mysql_php should be installed. I shall try that way

But why it is required? What is its function?

How did you install the PHP? Did it get compiled with mysql support? If you're using Debian, generally you apt-get php5-common, then install php5-mysql. It's not enabled by default (I don't think anyhow).

If you didn't install php from a package manager, you may need to enable it in the php source during the configure stage (although I thought this was now enabled by default).

Since there are so many extensions available for PHP, they only enable certain ones by default, and you enable/disable the ones you need.

Yes : the posting done by eaglek96 is close to my doubt

During configurations set up, we have to enable it.

My doubt is that much enough?

Is there anything I have to do with apache (means recompilation)

What is the order of installation

Apache, Mysql, php?
