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"
}
