( resource handle, int length [, string ending] )
Returns a string of up to length bytes read from the file
pointed to by handle. Reading ends when
length bytes have been read, when the string specified by
ending is found (which is not included
in the return value), or on EOF (whichever comes first).
If an error occurs, returns FALSE.
This function is nearly identical to fgets()
except in that it allows end of line delimiters other than the
standard \n, \r, and \r\n, and does not
return the delimiter itself.
