The get function is
one you'll use a lot. It returns the text located from
index1 to
index2. If
index2 isn't specified, only the
character located at index1 is returned.
The usage of get is as follows:
$t = $text->get(index1 [ , index2 ]);
As with any index ranges, index1 must be
less than or equal to index2, or an empty string will
be returned.
