+ Prototype: int fwrite ( resource $handle,string string, [, int $length] );
+ Description: fwrite() writes the contents of string to the file stream pointed to by handle.
+              If the length arquement is given,writing will stop after length bytes have been
+              written or the end of string reached, whichever comes first.
+              fwrite() returns the number of bytes written or FALSE on error
