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"
}
