How can I tell if php is installed?

no_names_left · 01-05-2005, 11:53 AM

Hi,

I have a fresh installation of Fedora 2 and can't work out if php is installed or just wrongly confirgured.

I final got apache running after starting the httpd service, not as I would have thought by starting 'apache' service. Is there something similar with php?

Thanks,

James

Create a new php document in your httdocs folder (or another if you changed the /www root) and type:

Code:

<?php phpinfo(); ?>

Save it as phpinfo.php and open Firefox (Mozilla) and go to http://localhost/phpinfo.php. If a page displaying your php info is served, php is properly installed and configured. If not, it is either not configured with Apache or not installed at all.

EDIT: Bad code.

Thanks Slayer097,

my phpinfo.php didn't work. The webpage was black with the source :
<html><body></body></html>

So how can I tell if it badly configured or not installed?
Is there something I can search for on the filesystem?

You misunderstood me. I'm sorry I was under the impression that you have some experience in web development. Open up the php document in a text editor (plain text, not OpenOffice) -- I believe in FC2 you can right-click and open with...) Delete any <html>, <head>, or <body> tags, and copy and paste in that line into it and save it as a php document. Make sure that you open it through localhost (i.e. not through file:///home/www/phpinfo.php), and see if you get the same results.

I have coded with php before and did put the right code in: <? phpinfo(); ?> but the webpage produced was blank - hence me thinking that php wasn't working properly.

I presumed that if apache producted <html><body></body></html> it might mean something.

Hum..

Slayer097 · 01-05-2005, 12:34 PM

If your browser displayed <html><body></body></html> then the webpage wasn't being served by Apache, just viewed in plain text. Either Apache isn't working or the source of the webpage is:

Code:

<html>
<body>
&lt;html&gt;&lt;body&gt;&lt;/body&gt;&lt;/html&gt;
</body>
</html>

Chances are Apache isn't serving the webpage (it's not configured properly). Again, check your address bar and make sure your not viewing the file (file:///home....) and going to localhost.

It is difinitively going through the localhost/phpinfo.php and apache is definively working as I have got html files to work.

Slayer097 · 01-05-2005, 12:50 PM

Hmmm. Have you seen the "Apache has been installed successfully page" yet? Non-dynamic content (html files) can be displayed fine without a web server, but as long as you are going through localhost, that should mean Apache is installed (try going to http://localhost). Otherwise, I can't think of what's wrong.

no_names_left · 01-05-2005, 12:54 PM

Yep, I have got the "If you can read this page, it means that the Apache HTTP server installed at this site is working properly".

So I think apache is okay. This all seems rather random to me,

Is there a service to start with php?

Slayer097 · 01-05-2005, 01:12 PM

I have no idea what's wrong then. I hope you can sort out your problem, but seeing as I'm not running FC2 I don't think I can help you much more. Sorry

running "$rpm -qa | grep -i php" will confirm whether php is installed or not. If it is, apache on fedora will recognise this.

no_names_left · 01-05-2005, 01:50 PM

Hi,
I got the following....

[root@localhost root]# rpm -qa | grep -i php
php-mysql-4.3.10-2.4
php-pgsql-4.3.10-2.4
php-odbc-4.3.10-2.4
php-mbstring-4.3.10-2.4
php-4.3.10-2.4
php-pear-4.3.10-2.4
php-ldap-4.3.10-2.4

So I must have installed.

reddazz · 01-05-2005, 04:15 PM

Yes you do have it installed. Try writing a simple php script and putting it in your webserver directory and see if it works. In fedora core 2 place the test page in /var/www/html and try and access it as follows http://localhost/testpage.php if it's been saved as testpage.php.
