Hi anilsoni7 welcome to the forum.

Based on the warnings it seems that the problems are in this lines:
The first 2 warnings the problem seems to be that the fopen is not opening the $CF_QUESTIONFILE right so it returns FALSE. I would double check that $CF_QUESTIONFILE holds a valid path. (On I side not I find the functions file and file_get_contents easier to work with then the fopen,fread,fclose combo).

The last warning is basically saying that the encode_decode function doesn't exist. I know it doesn't exist in PHP so make sure it is implemented before it is used, either in the same file or in the require_once/require/include_once/include files.

P.S. Please use the PHP tags so that the PHP code retains the indentation when copied and is syntax highlighted. Easier to read.
