8 Prototype: resource fopen(string $filename, string $mode

10 Description: Opens file or URL.
11
12 Prototype: bool fclose ( resource $handle );
13 Description: Closes an open file pointer
14
15 Prototype: bool feof ( resource $handle )
16 Description: Returns TRUE if the file pointer is at EOF or an error occurs
17   (including socket timeout); otherwise returns FALSE.
