PHP ini development concept seems pretty straightforward to me, anyway I can't figure out how to make a php.ini setting to be "admin value", e.g. not changeable with `ini_set()` function from within php script, whatever access type its definition has. I looked into apache mod_php5 module source, to find out how php_admin_value/flag is implemented, and it seems there's special handler, different than "normal" variable change handler. Type of php.ini variable access is controlled via third argument to PHP_INI_ENTRY() macro, anyway php_admin_value implementation overrides it somehow, I mean no matter what kind of access was defined with the variable definition in php source, if the value is set with php_admin_value, it is not changeable later, and this is exactly what I want. There's also a modification handler for php.ini variables, but obviously this is also variable-definition setting, I mean, if e.g. modfication handler for mysql.port is onUpdateString, I cannot in my extension change it to OnOtherUpdateStringProcedure, as mysql extension's php ini variables are already defined in mysql extension source. Anyway with mod_php php_admin_value/flag does it somehow (make php ini variable unchangeable). To be exact - I want to set any php.ini variable inside extension code - and this is something I know how to do it - and mark it to be "admin value" (not changeable later) - and this is something I cannot figure out. I actually use php as cgi/fcgi, and since I noticed, that command-line specified variable (-d switch) is not automatically marked as "admin value" (works according with variable access type). The only one advanced php api information I could find was "Extending and Embedding PHP" book, written by Sara Golemon, anyway php.ini chapter does not say anything about overriding original access type setting.
