Thanks zqichik for the reply.

I tried your command even as a root user too. It was negative.


[nissanka@c83-250-111-43 ~]$ php -i
bash: php: command not found
[nissanka@c83-250-111-43 ~]$ su root
Password:
[root@c83-250-111-43 nissanka]# php -i
bash: php: command not found
[root@c83-250-111-43 nissanka]#


How do I try from a webpage?

The easiest way is to write a script containing just the one line:

Save that as test.php and put in the DocumentRoot directory of the webserver.

I can pretty much tell you right now it's not installed, though. The path to php ought to be /usr/bin or /usr/local/bin, or something that would be in the path of the root user.

Thanks zaichik for the reply.

[nissanka@c83-250-111-43 ~]$ cd /usr
[nissanka@c83-250-111-43 usr]$ cd local
[nissanka@c83-250-111-43 local]$ cd bin
[nissanka@c83-250-111-43 bin]$ ls
clamav-config* clamdscan* clamscan* freshclam* sigtool*
[nissanka@c83-250-111-43 bin]$

[This clamav means an anti-virus program.]

It seems there is no php in the directories you mentioned.

What do you mean by the Document Root directory of the webserver? I am trying this on my home computer. Where do I find the Root directory? Obviously, I can log in as a root user.

Please leave your comment here. I am leaving home soon for the gym and afterwards I will go to work. So I will attend this tomorrow. I will come home very late in the evening.

This command:
will tell you where PHP is installed, if at all. Again, I can all but guarantee you that it's not installed.

The DocumentRoot is the directory from which Apache will serve pages. You can find out what that is by finding your httpd.conf file and grepping for DocumentRoot:

locate -u
locate httpd.conf
grep DocumentRoot /path/to/httpd.conf

You'll get several lines of output, including one that looks like this:

DocumentRoot /usr/local/apache/htdocs

or maybe

DocumentRoot /var/www/html

That directory is the one from which Apache will serve douments. So (assuming the first DocumentRoot), if you put test.php in /usr/local/apache/htdocs, then /usr/local/apache/htdocs/test.php is served by Apache when you open http://<your IP address>/test.php in your browser.

Good luck.

It seems now I have installed and PHP and it is working. I am posting a part of the output I have received for the command '' php -i ''.

Please tell me whether I am correct.

[nissanka@c83-250-108-144 ~]$ php -i

You probably need to be root..

Thanks Nylex for taking time to reply me.

Is the following fine?

Do I have working PHP?

How can I test?

This is my home computer. I don't have a network. I have already installed mysql. It works fine.

You already tested PHP and it appears to be working.
