PHP data corruption in form submission on new server

One of my variables "link1" that is storing a bunch of urls is having random lines being duplicated on form submission. I just recently swithed servers from a PHP 4.3.3 to a 4.2.2 version. This error has only started appearing on the new machine. The script worked fine on the old server and still does on the test server. Any ideas? I think it might have to do with the ini config. i am stumped. here is a link to my code. http://host107.ipowerweb.com/~madpundi/bad.php this is the links that the form should echo http://host107.ipowerweb.com/~madpundi/exgood.php thiis is what it is echoing after submit http://host107.ipowerweb.com/~madpundi/exbad.php i have debugged my code and traced it all. i have the script running flawless on the old server and on a local test server. there is just something about data transmission in submitting that screws it up. i think it is a ini misconfig, but i cant see anything that would cause that. i included the 2 php info files, incase i am missing something. i am stumped as to what to do now. the only thing i know to try is compile php/apache/mysql from scratch from the latest versions. (the colocation setup used rh9 rpms, so the versions are slightly old and all the data is scattered in custom locations). i have had nothing but trouble and errors in all my rpm endeavors. here is the phpinfo() from the old server http://host107.ipowerweb.com/~madpundi/oldserver.htm here is the phpinfo() from the new server http://host107.ipowerweb.com/~madpundi/newserver.htm
