[PHP] Reg patch for PHP4.0.6

[SenthilVelavan]

Hello Folks,
                    I have applied a patch from 
http://www.php.net/do_download.php?download_file=rfc1867.c.diff-4.0.6.gz
for PHP 4.0.6. Is my patched PHP4.0.6 is compatible to PHP4.2.2. If not please list 
the features or bugs that are not fixed with my patch applied version.

Which one is advicable?
1.Either the PHP4.0.6 with patch from 
http://www.php.net/do_download.php?download_file=rfc1867.c.diff-4.0.6.gz
OR
2.To directly go for PHP4.2.2

Any help is appreciated.

Advance thanks and regards,
Senthil.
