Re: Simple Unidentified Variable

Hi, Everyone makes it sounds that since 4.2.0 it's impossible to do: http://www.example.com/foo.php?a=apple print $a; // apple It is still very possible. The main way to make this possible is via the register_globals directive, a PHP setting that can be changed in PHP's configuation file, php.ini The default of this directive changed from on to off as of 4.2.0, this is just the default. Everyone should read php.ini as it contains information about many directives that affect our scripts. Please do not hesitate to ponder over php.ini: http://cvs.php.net/co.php/php4/php.ini-dist There are several ways to "reflect" the behavior of register_globals, methods include: 0) turning it on in php.ini (sysadmin) a) .htaccess : if the sysadmin allows use of .htaccess, then the following will work in it: php_flag register_globals on b) use extract() or import_request_variables() c) don't code with this behavior Check the archives for more tips, I've ranted a few times in the recent past :) Such as: http://marc.theaimsgroup.com/?l=php-general&m=102036870428992 And btw, undefined variable errors are of level E_NOTICE and configured via either the error_reporting directive in php.ini or at runtime via the error_reporting() function.
