Example #1 TokyoTyrantQuery::hint example
<?php
$tt = new TokyoTyrantTable("localhost", 1979);
$tt->vanish();
for ($i = 0; $i < 11; $i++) {
$tt->put(null, array('a_col' => 'a' . $i, 'b_col' => 'b' . $i));
}
$query = $tt->getQuery();
$query->addCond('a_col', TokyoTyrant::RDBQC_STRBW, 'a');
$query->search();
var_dump($query->hint());
?>
