Hi, I am having problem in aptana studio 3,in my html file i put php code but it always says tha "<" missing '>' for end of tag
it's pointing in this php code

  echo 'hello aptana';

I already fix the html file association with php,and now the php code is formatted in php means to say it color white same as in php file,i thought it is working but when i try to save the html file with php code,it generate error as what i said above.

how can fix this?Thank you in advance.
