PHP code commented out on apache server
Posted: Sun Mar 23, 2014 5:59 am

I have followed numerous tutorials on how to setup a basic LAMP server on my Pi running Raspbian Wheezy, and have got the initial 'index.html' to run correctly, and connected from another device on my home network.
Although I have supposedly successfully installed apache2, php5, mysql-server, mysql-client, and php5-mysql, PHP still isn't functioning properly. Any HTML code in a .php file will display - but PHP code is displayed in my browser element inspector as commented out, or other weird stuff. Here is an example. I have a file in my /var/www/ directory called phptest.php, and its content is simply:
When I open the page in-browser, however, it will show as:
Code: Select all
<html><head></head><body><pre style="word-wrap: break-word; white-space: pre-wrap;"><?php
phpinfo();
?>
</pre></body></html>
or
Can anyone please help me fix this?
I hope this is the right place to ask, sorry if not.
Thank you for your time.

As php5 pulls in libapache2-mod-php5, you shouldn't need to do the a2enmod manually, but it is worth a try, as is restarting your apache server afterwards.
Your code should work. I just tried it and it did.

Hi there, the a2enmod command returned:
Code: Select all
ERROR: Module php5 does not exist!
Does this mean it was incorrectly installed?

Is libapache2-mod-php5 actually installed? It should be.
You can check with
If you get something that starts with "ii", then it is installed. It should look a bit like this (except I run apache on a PC, not a Pi, so some bits will differ, like it will say 'armhf' instead of 'i386', the rest should be the same)
Code: Select all
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Architecture Description

Okay, I tried that and it returned
Code: Select all
iU libapache2-mod 5.4.4-14+deb armhf server-side, HTML-embedded script
I'm sorry if I don't pick up on what you're doing, I'm pretty new to the Pi.

sudo apt-get install libapache2-mod-php5
should fix it.

Hi, apparently it's already installed to to the newest version...

It looks like the install has been requested, but failed for some reason.
The first "i" means "Desired state = Installed".
The "U" means "Current state = Unpacked", which is part way through the install procedure of Download, Unpack, Setup, Install, Configure.
The question is why it failed?
Try sudo apt-get -f install and if it fails post the entire output of the command here.

Okay it's pretty long, but here's what happened
Code: Select all

Ok, thanks for that. The detailed report is exactly what was needed to diagnose this issue.
It looks like mysql can't be configured due to a problem with "mathkernel" which I believe is part of the wolfram maths system that is installed on Raspis by default now. I don't have that package installed (it's too big, has this annoying bug and I don't need it for anything I do). I can't remember the full name of it, but if you can find it, or someone else can prompt with details) and you don't use it, then removing it would be a good idea and free up about 0.5GB of space on your card. If you do need it, I'm sure someone who knows what they are doing can tell you how to edit the start up files for that software so they work correctly.
Then, you should be able to run that apt-get -f install and complete the install of mysql, apache and php

sudo apt-get purge wolfram*
gets rid of that mathkernel script and frees up 500MB of space.
