范例
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
