That is some truly disgusting code...
Could you give us a large snippet?
Parse error: syntax error, unexpected $end in /home/content/12/9807012/html/wp-content/plugins/exec-php/includes/runtime.php(42) : eval()’d code on line 30
Suggests that you haven't given us the right snippet of code; we need this file: (that riduclous location here)/includes/runtime.php
Just post the entire thing if you could
