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"
}
