Example #1 TokyoTyrantQuery iterator example
<?php/* Connect to a table database */$tt = new TokyoTyrantTable("localhost", 1979);/* Add rows */$tt->put(null, array("column1" => "some data", "column2" => "something here"));$tt->put(null, array("column1" => "more data", "column2" => "best data this far"));$tt->put(null, array("column1" => "again data", "column3" => "foobar here"));$tt->put(null, array("column45" => "random data", "column2" => "something along the lines"));$tt->put(null, array("column21" => "test data", "column2" => "generating.."));$tt->put(null, array("column1" => "foobar data", "column2" => "value here"));/* Get a new query object */$query = $tt->getQuery();/* Add a search condition */$query->addCond("column2", TokyoTyrant::RDBQC_STROR, "something");/* Iterate the results */foreach ($query as $key => $value) { echo "pk: $key, columns: ", count($value) ,"\n";}?>
以上例程的输出类似于：
pk: 1, columns: 2 pk: 4, columns: 2
