PHP and Java. Steps to follow to be able to start using them.

glore2002 · 10-05-2008, 01:00 PM

Hello back!

I would like to start Programming in PHP and Java under Slackware (12.1). So, I would really appreciate if you could help and tell me everything I have to install or check If they are already installed to be able to start programming under both of them (PHP and Java). Advices and book recommendations will be also very welcome.

Please, answers should be for a "newbie".

Thank you!

if you did a full install, everything is setup to start programming in php, but for java you need the JDK.

JDK is available in extra/ on your install CD (CD 4)/DVD or from your favourite Slackware mirror.

I do most of my Java programming on Slackware...it's a breeze.

As said the JDK is available in /extra.

Both Netbeans and Eclipse work effortlessly on Slack.

Thanks for your replies. I've installed JDK. Now I will install Eclipse and /or Netbeans.

What else should I install? Apache, MySQL?

I really appreciate your help.

it might be a good idea to install mysql if you are going to use database in php, and you only need apache if you going to be hosting a website on your machine

Ohh, I see. I thought Apache was necessary as well as MySQL. I've activated both of them.

So, if I write a program in PHP such as:

Code:

<html>
<head>
<title></title>
</head>
<body>
<h3>My first php program</h3>
<?php echo "hello my world"; ?>
<hr>
</body>
</html>

And I save it as hello.php

What should I do to make it work?

Thanks,

I think all I had to do to get PHP working was edit /etc/httpd/httpd.conf:

Code:

# Uncomment the following line to enable PHP:
#
Include /etc/httpd/mod_php.conf

I also enabled user home directories for testing by uncommenting the following line:

Code:

# User home directories
Include /etc/httpd/extra/httpd-userdir.conf

which meant I could put my php files in /home/gsl/public_html and access them using http://localhost/~gsl/file.php. If you edit httpd.conf, restart Apache (or start it if, like me, you don't run it by default).

A good PHP test file is:

Code:

<?php phpinfo(); ?>

There may be some step I have forgotten. My PHP experience is limited.

Thank you!
It worked perfectly well.

After installing JDK What can I do to check Java was installed fully and correctly?

Thanks,

To check whether the JDK is installed correctly...

java -version

will determin the version of the jre - same as installation...

javac --help

should show you the options for the javac command...

Or Alterantively create a simple test program...HelloWorld would suffice...

compile it with javac...execute the resulting class file with java (remember the classpath)...

It would also be good idea to edit the sh files in /etc/profile.d relating to your new java installation...
