9 line function logic problem

Hi, I am going crazy with this function please have a look at it and tell me what i am doing wrong. This is my setup: I have a file called one.html.cache in the directory /cache/ in one.html.cache I have a time()+ 3600 number (eg: 1096224755) I need to know if the number in that file is still bigger than the present time() or not the problem is, it is always returning zero... heres the function: echo "b".is_cache("one.html"); function is_cache($get_file) { $th_file = $include_path.$get_file . '.cache'; $fp = fopen($th_file, 'a+'); fseek($fp, 0); $rd = fread($fp, filesize($th_file)); fclose($fp); if (time() - $rd > 5) return 0; else return 1; } What am i doing wrong? or is there a better way of doing this?
