Regarding the statement by the earlier poster that:
"Unfortunately, you almost never want to know the original value in the config file. Instead, you want to know the value currently in effect."
I have found this useful for changing the error reporting levels for a few specific pages while testing. I turn on all error_reporting while testing, but for a few pages I want to turn off notices. So, I put this at the top of the page:
<?php
error_reporting(8183);
?>
and this at the bottom:
<?php
error_reporting(get_cfg_var('error_reporting'));
?>
to put it back to whatever default I had at the time.
get_cfg_var
(PHP 4, PHP 5)
get_cfg_var — Gets the value of a PHP configuration option
Description
string get_cfg_var
( string $option
)
Gets the value of a PHP configuration option.
This function will not return configuration information set when the PHP was compiled, or read from an Apache configuration file.
To check whether the system is using a configuration file, try retrieving the value of the cfg_file_path configuration setting. If this is available, a configuration file is being used.
Parameters
- option
-
The configuration option name.
Return Values
Returns the current value of the PHP configuration variable specified by option, or FALSE if an error occurs.

get_cfg_var returns the value from php.ini directly,while the ini_get returns the runtime config value. I have tried it on PHP 5.1.6
[EDIT by danbrown AT php DOT net: The author of this note means that ini_get() will return values set by ini_set(), .htaccess, a local php.ini file, and other functions at runtime. Conversely, get_cfg_var() will return strictly the server php.ini.]
