PHP Fiies Won't Open, How to Fix?

[rpdom]

I either open the file in the Terminal or open it directly in the - /var/www/html - with the browser.

Neither of those methods will work as you are just reading the source file. It won't be executed by php.

Even if I navigate to the files using http://localhost it does the same thing. Just downloads them to the Downloads folder.

That method, however, should work, if PHP is enabled in the server.

How can I enable the .php files to load from these folders? It worked in the /var/www/html folder before.

If I do that I get a "The requested URL - /var/www/html/processorder.php - was not found on this server."

PHP is not working? How do I make sure it's working on my RPi?

Unless (in your terminal) you run something like "php /var/www/html/index.php" then they won't normally be run through the php engine. You may be able to get a similar effect if you have a "#!/usr/bin/php" as the first line, but they they probably won't be usable via apache.

Loading that path in your browser won't (and never will have worked).

There is a reason that several people said use http://localhost/index.php, as that will use the network socket that goes via apache rather than talking direct to the filesystem.

When you use that method what's the contents of the downloaded file, make sure you're actually looking at the contents of the file you just downloaded (not the file in /var/www/html or something you downloaded yesterday.

Also when you do that what does a tail on the apache logs show. Normally you should see an entry in the access.log when you request the file via http://localhost/

Here is the log.

Code: Select all

==> /var/log/apache2/access.log <==
::1 - - [28/Dec/2016:01:33:48 +0000] "GET /index.php HTTP/1.1" 200 22668 "-" "Mozilla/5.0 (X11; Linux armv7l; rv:45.0) Gecko/20100101 Firefox/45.0"

That might suggest that the php side of things is working, It looks like it's generating a 22k html page. If you opened the contents of what's been downloaded you'll probably see a lot of html rather than the phpinfo command (assuming that's what's in your index.php)

Rather than a browser you can also use curl in the command line (curl http://localhost/index.php) which should show the resulting html on standard out.

This would suggest that apache isn't telling the browser it's html code so as the browser doesn't know how to deal with it you get a file to download. This is probably an issue with the mime headers, I'm not sure off hand what config you have to change for that.

Yes, it outputs a whole lot of HTML.

I need to put a doctype header in the .php files and .html files to get them to work?

[php]

Tried to use different HTML doctypes in .php files. Still didn't load.

[php]

How do I check/fix the mime headers? Anywhere on this forum I should specifically ask?

Grab a fresh SDCard, get a copy of Raspbian installed. Then run
sudo apt-get install apache2 php5 php5-cli libapache2-mod-php5
Add /var/www/html/index.php with sudo nano

Code: Select all

<?php
phpinfo(); 
?>

restart the webserver then point your browser at http://192.168.3.14/ (or http://pi.local/)

There's got to be something you've missed or messed up on your current system, so starting from a clean install is more likely to get sensible results.

You can also use a used SD card and erase it first.

It seems like you've changed something else in the config which means the ouptput from your php isn't being treated as html by the browser, rather than spending hours of time trying to find what bit of config you've changed from the default it's probably easier to start from scratch.

When starting from scratch you may want to keep a backup of the files you change, that way if something breaks you can (more) easily find the bit that changed to break it.

Any change in the config wasn't something I did.

I'm going to try Ubuntu Mate. Raspbian seems to be too much of a PIA just for a LAMP stack. I typically don't have issues with Linux Mint or Ubuntu derivatives.

This is exactly the way I was thinking.

I suspect very much that it is something you've done. Most people seem to setup a LAMP stack fairly easily. The Ubuntu packages are going to be very similar (potentially the only difference being branding) as the Raspbian ones as they both use Debian as their base.

[php]

1. Wiped the SD card
2. Reformatted to FAT32
3. Installed Ubuntu Mate for RPi2 on SD card
4. Installed new OS, rebooted
5. Run terminal commands @DougieLawson suggestedp
6. Didn't say php5 was available, but php 7.0 is, installed php 7.0
7. Checked Apache works by going to localhost
8. Checked Apache was running using - service apache2 status - it was
9. Put .php files into /var/www/html/ as admin
10. Still won't load files, tries to donwload
11. WTF?

I have not installed MySQL.

Did you install libapache2-mod-php? You need that for Apache to recognise and execute PHP files.

FWIW, I find it very simple to set up a working LAMP stack on Raspbian, Debian and Ubuntu.

I usually use phpmyadmin (even though it's horribly insecure without some extra effort) to pull in all the dependencies.

sudo apt-get install apache2 mariadb-client phpmyadmin php5-cli

Installed it, still gave me a "page not found" in Firefox. Any other suggestions?

"Page not found" and getting a file to download are not the same error. One indicates apache can't find the html/php file the other suggests a misconfiguration of apache.

When I try to open it with Firefox it gives a File:/// path and keep giving me an "Opening processorder.php" page.

I then replaced that with localhost which gives me "Not found - The request URL ____ was not found on the server". Localhost is the correct path?

[rpdom]

Using a file:///... path for a PHP file in a browser won't work. It is getting the file directly and just displaying it, not getting it from the web server which will process it first.

Where is the file on your file system?

What URL(s) are you trying to use to access that file?

That's just the way Ubuntu Mate automatically processess it.

Files are in /var/www/html, I use http://localhost/var/www/html/whatever.php.

Files are in /var/www/html, I use http://localhost/var/www/html/whatever.php.

If /var/www/html is the document root for your webserver, you should be trying http://localhost/whatever.php or http://127.0.0.1/whatever.php

You don't put the full local file path in the URL.

Thanks, that worked!

In the book I have it shows the path to the folder where the file is in the browser. Can I do this on Ubuntu? Should I just put them into - /var/www/html - and then use localhost?
