Apache App

Hi, i have moved an app to a new VM.  one section of the site is not working.  I am receiving this error in the apache2 log:

PHP Fatal error:  require_once():  Failed opening required '../../../lib/init.php'
(include_path='/usr/share/php:/usr/share/pear') in /var/www/directory/index.php on line 8

Thanks,

Jackson

Undefined variable messages are "Notice" level messages.  These are suppressed in PHP by default, thus allowing you to use undefined variables as if they were NULL, FALSE or zero.  So it may be that the old version of the error reporting was something like this:

error_reporting(E_ALL ^ E_NOTICE);

Personally, I always use error_reporting(E_ALL) so that I can see the Notice messages, because when I encounter an undefined variable, it is usually a typographical error on my part.  But if your script is designed to use undefined variables silently, you may want to change the error reporting to stop the Notice messages.

Hi Jackson,

When you open file:

/var/www/directory/index.php

what configuration is on line 8?

Are you running a 64 bit or 32 bit system?

Where is your php.ini file located?

When you moved your app to the new VM did you recompile apache and php with the same modules as on the previous server?

What version of PHP are you running on the original server and on the new server?

If you create a phpinfo.php file on both servers in the /var/www/appfolder with the following content:

<?php phpinfo(); ?>

You can then go to URL/phpinfo.php This will give you your PHP information for each server so you can compare modules. (remember to remove this after as it is a security risk giving everyone your PHP information).

For apache you can check loaded modules by locating your apachectl file and running /path/apachectl -M or /path/httpd -M this will show loaded modules.

Line 8 of index.php probably says something like this:

require('../../../lib/init.php');

The fatal error means that the path to the init.php script does not point to the right place.  The script may be missing or it may be in a different directory tree.

You are correct about how the line reads.  Where should the init.php file be located?

Ray PaseurCommented:
Anywhere you want!  Just be sure the require() function calls for the correct path.

I'm a bit new to php, how do I know where it is looking for it.  I see the prefix of the location
.../.../.../lib/init.php

What directory does the .../ represent?

Ray PaseurCommented:
I believe that it is two dots between the directory separators.  A google search for ../ relative path turns up this.
http://en.wikipedia.org/wiki/Path_%28computing%29

So I guess that the ../../../ is telling the machine to look "up" three parent directories above the existing directory.
