- Improved php.ini handling: (Jani)
. Added ".htaccess" style user-defined php.ini files support for CGI/FastCGI
. Added support for special [PATH=/opt/httpd/www.example.com/] sections
All directives set in these sections will not be able to be overridden
in user-defined ini-files or during runtime in the specified path
. Added support for special [PATH=/opt/httpd/www.example.com/] and
[HOST=www.example.com] sections. Directives set in these sections can
not be overridden by user-defined ini-files or during runtime.
. Added better error reporting for php.ini syntax errors
. Allowed using full path to load modules using "extension" directive
. Allowed "ini-variables" to be used almost everywhere ini php.ini files
. Allowed using alphanumeric/variable indexes in "array" ini options
. Added 3rd optional parameter to parse_ini_file() to specify the scanning
