范例

Example #1 TokyoTyrantQuery::addCond() 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" => "not 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 */
$query->addCond("column2", TokyoTyrant::RDBQC_STROR, "something");
/* Dump the search results */
var_dump($query->search());
?>

以上例程会输出：

array(2) {
  [1]=>
  array(2) {
    ["column1"]=>
    string(9) "some data"
    ["column2"]=>
    string(14) "something here"
  }
  [4]=>
  array(2) {
    ["column45"]=>
    string(11) "random data"
    ["column2"]=>
    string(25) "something along the lines"
  }
}
