Usage of phpinfo() in gd_version() of captcha.php

[laurent.duretz]

In gd_version() of captcha.php, you parse the phpinfo() result to retreive the GD version if GD is loaded.

GD provide the method gd_info() which return the version.

It's:
-> More easy to code
-> More easy to read
-> More efficient when phpinfo() is disabled by web hoster ;-)

Translation please?

It means we should use gd_info() to determine the version of GD installed instead of parsing the output of php_info().

In the comments section of the gd_info() page, a user provided a way to take advantage of gd_info on newer systems (PHP 4.3+) while falling back on php_info() for older versions of PHP. It also caches the gd version so it doesn't have to be recalculated every time.

MyBB still using phpinfo...

Since PHP 4.3.0 the http://php.net/gd_info func' is available, considering MyBB dropped support for PHP 4, why not gd_info()?

We also can read the constant GD_VERSION since PHP 5.2.4, so I would suggest to check it before the use of phpinfo().

we use gd_info for 1.6 and above. 1.4 still will stay compatible with PHP 4
