settings with the value of 'yes' will be returned as '1'.
//#my ini file
//A = 1
//B = any-thing
//C = yes
//D = /some/path/file
get_cfg_var('A') // returns '1'
get_cfg_var('B') // returns 'any-thing'
get_cfg_var('C') // returns '1', wait, why?
get_cfg_var('D') // returns '/some/path/file'
I had my setting = yes and then checked it as ==="yes" for epic fail.

get_cfg_var — Gets the value of a PHP configuration option
Gets the value of a PHP configuration
This function will not return configuration information set when the PHP was compiled, or read from an Apache configuration file.

The configuration option name.

FALSE if an error occurs.
|5.3.0||get_cfg_var() was fixed to be able to return "array" ini options.|
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.]
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:
and this at the bottom:
to put it back to whatever default I had at the time.
