+ Prototype: string fread ( resource $handle [, int $length] );
+ Description: reads up to length bytes from the file pointer referenced by handle. 
+   Reading stops when up to length bytes have been read, EOF (end of file) is 
+   reached, (for network streams) when a packet becomes available, or (after 
+   opening userspace stream) when 8192 bytes have been read whichever comes first.
