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";
}
?>

Il precedente esempio visualizzerĂ  qualcosa simile a:

pk: 1, columns: 2
pk: 4, columns: 2
