get_cfg_var

(PHP 4, PHP 5)

get_cfg_var — PHP 설정 옵션의 값을 얻습니다.

설명

string get_cfg_var ( string $varname )

varname 으로 지정한 PHP 설정 변수의 값을 반환하거나, 에러가 발생했을 때 FALSE를 반환합니다.

PHP 컴파일시에 설정했거나, (php3_configuration_option 지시어를 이용하여) 아파치 설정 파일에서 읽는 정보는 반환하지 않습니다.

시스템이 어떤 설정 파일를 사용하는지 확인하려면, cfg_file_path 설정값을 확인해보십시오. 존재한다면, 그 설정 파일을 사용합니다.

참고: ini_get().

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 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.]
