范例

Example #1 TokyoTyrantTable::putCat() example

<?php
/* Connect to a table database */
$tt = new TokyoTyrantTable("localhost"1979);

/* Passing null to put generates a new uid */
$index $tt->put(null, array("column1" => "some data""column2" => "more data"));

/* Get the row back */
var_dump($tt->get($index));

/* Modify an existing row */
$tt->putcat($index, array("column1" => "something new""new_column" => "other data"));

/* Get the row back */
var_dump($tt->get($index));
?>

以上例程会输出:

array(2) {
  ["column1"]=>
  string(9) "some data"
  ["column2"]=>
  string(9) "more data"
}
array(3) {
  ["column1"]=>
  string(9) "some data"
  ["column2"]=>
  string(9) "more data"
  ["new_column"]=>
  string(10) "other data"
}
