范例
Example #1 TokyoTyrantTable::putKeep() 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)); try { $tt->putKeep($index, array("column1" => "something new", "new_column" => "other data")); } catch (TokyoTyrantException $e) { if ($e->getCode() === TokyoTyrant::TTE_KEEP) { echo "Existing record! Not modified\n"; } else { echo "Error: " , $e->getMessage() , "\n"; } } /* Get the row back */ var_dump($tt->get($index)); ?>
以上例程的输出类似于:
array(2) { ["column1"]=> string(9) "some data" ["column2"]=> string(9) "more data" } Existing record! Not modified array(2) { ["column1"]=> string(9) "some data" ["column2"]=> string(9) "more data" }
