Digg  get_cfg_var
Gets the value of a PHP configuration option
(PHP 4, PHP 5)
Code Examples / Notes » get_cfg_varstephen
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: error_reporting(8183); and this at the bottom: error_reporting(get_cfg_var('error_reporting')); to put it back to whatever default I had at the time. verdana
ini_get() return the current value of the configuration option. But the get_cfg_var() always get the value from config file, php.ini. This is the test code: ini_set('sendmail_from', 'verdana@263.net'); echo '<br /> <br />'; echo '<br /> Current Value:'; var_dump(ini_get('sendmail_from')); echo '<br /> Value in cfg file:'; var_dump(get_cfg_var('sendmail_from')); digitalife
ini_get() return the current value of the configuration option. But the get_cfg_var() always get the value from config file, php.ini. ------------------------------------------------------ In PHP4.3.0£¬I test this in WindowXP£¬I found the Get_Cfg_Var() and ini_get() is same return the current value of the configuration,not from config file php.ini NOW!!! matt
If you are using PHP 4.0+ (and if not, why not!) use ini_get(). This will return the local value - even if you've set it via apache in http.conf as I did during testing. surfchen
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

As implemented, this function is an odd wart--it calls cfg_get_string, which returns the value originally set in the config file, if any. Unfortunately, you almost never want to know the original value in the config file. Instead, you want to know the value currently in effect. (These two values can be different if you have no php.ini file, or if you're setting options in httpd.conf or .htaccess files.) To get the current value of a configuration option you should use ini_get() instead |
