TokyoTyrant::putKeep — Puts a record
Puts a key-value pair into the database or multiple key-value pairs. If keys is string then the second parameter value defines the value. The second parameter is mandatory if keys is a string. If the key already exists this method throws an exception indicating that the records exists.
This method returns a reference to the current object and throws TokyoTyrantException on failure.
Beispiel #1 tokyotyrant::putKeep() example
<?php
/* Connect to a database on default port */
$tt = new TokyoTyrant("localhost");
/* Create a new key */
$tt->put("key", "value");
try {
$tt->putKeep("key", "new value");
} catch (TokyoTyrantException $e) {
if ($e->getCode() === TokyoTyrant::TTE_KEEP) {
echo "Existing record! Not modified\n";
} else {
echo "Error: " , $e->getMessage() , "\n";
}
}
echo $tt->get("key");
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Existing record! Not modified value
