Fgets ();-- reads a line from the file pointer

String fgets (resource $handle [, int $length]) / / reads a line from the file pointer.

Parameter: handle: the file pointer must be valid and must point to a file successfully opened by fopen () or fsockopen () (which has not been closed by fclose ()).

Length: reads a line from the file pointed to by handle and returns a string up to length-1 bytes in length. Encounter a newline character (included in the return value), EOF, or stop after reading the length-1 byte (see which case occurs first). If no length is specified, the default is 1K, or 1024 bytes.
