Example #1 TokyoTyrantIterator::__construct() example
<?php

$tt = new TokyoTyrantTable("localhost", 1979);
/* Passing null to put generates a new uid */
$index = $tt->put(null, array("column1" => "some data", "column2" => "more data"));
/* Construct an iterator */
$it = new TokyoTyrantIterator($tt);
foreach ($it as $value) {
var_dump($value);
}
?>
以上例程会输出：
array(2) {
["column1"]=>
string(9) "some data"
["column2"]=>
