Installed apache and PHP on a new server. Using include("blah.php"); works fine but it doesn't work when I try to include from the directory behind, include("../blah.php");
PHP.ini has both: allow_url_fopen = On allow_url_include = On
Does anyone know what is causing this?
According to the documentation
If a path is defined — whether absolute (starting with a drive letter or \ on Windows, or / on Unix/Linux systems) or relative to the current directory (starting with . or ..) — the include_path will be ignored altogether. For example, if a filename begins with ../, the parser will look in the parent directory to find the requested file.
When you include ("blah.php"); PHP uses the include_path, but if you use a relative specifier, like . or .., PHP builds a path relative to where it is, i.e. the currently executing script.
Is it a Windows installation? If yes, you are using the wrong directory separator. You can avoid such discrepancies by using the DIRECTORY_SEPARATOR constant:
include('..'.DIRECTORY_SEPARATOR.'blah.php');
You can also use absolute paths instead:
include dirname(realpath(__FILE__)).DIRECTORY_SEPARATOR.'..'.DIRECTORY_SEPARATOR.'blah.php'
/ as a directory separator.

Try including the full path to the file (e.g. /path/to/your/file) to see if its a context problem, you may be in the wrong directory. is_readable() is not the greatest function, try using file_exists to check if the file is there first. Also double-check the file permissions just in case.
Try using something like this:
include(dirname(__FILE__).'/../file.php')
The issue with relative includes is if you are not in the working directory you expect when you execute the file, they will fail. Remember, they are relative to getcwd(), not the location of the file. Using the dirname(FILE) trick means they end up relative to their actual location on disk.
Note that if you are using 5.3.x or above, you can use DIR instead of dirname(FILE)
Check your logs (or put error_reporting(E_ALL)). If a file is unreadable, or not loaded, you will see a log entry with an explanation. Paste it here if it doesn't help you.
