Retrieving Text
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 toindex2
, or an empty string will
be returned.
