EDIT the problem i encountered is whenever i checked http://localhost/log.php this appears:

Parse error: syntax error, unexpected ';' in C:\xampp\htdocs\log.php on line 7

i have tried modifying the syntax in numerous ways but the problem presist. I suspect my code may have some underlying fundamental problem that is not syntax related, but i can't tell due to my lack of experience. Again, any help/clue is greatly appreciated. Thank you very much
