include_once("t9input.class.php");

$input = "8378464";
$result = getPossibleWords($input);
var_dump($result);

Custom dictionary:

include_once("t9input.class.php");

$t9input = new T9input();
$input = "8378464";
$t9input->addDictionary("another_dictionary.txt", str_split($t9input->key[$input[0]]));
$result = $t9input->translate($input);
var_dump($result);
