`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.]

`settings with the value of 'yes' will be returned as '1'.

I had my setting = yes and then checked it as ==="yes" for epic fail.

Boolean-like values are evaluated as follows: "true", "on", "yes" evaluate to "1" (string 1), while "false", "off", "no" evaluate to "" (empty string).

`keep in mind get_cfg_var() returns a string(1) '1' for the value: On

A3=getcfgvar("A")==="1";//A3 = get_cfg_var("A") === "1";//A3=getcfgvar("A")==="1";//A1 is false //$A2 is false //$A3 is true ?>
