Example #1 TokyoTyrantTable::putKeep() example
<?php
$tt = new TokyoTyrantTable ( "localhost" , 1979 );
$index = $tt -> put ( null , array( "column1" => "some data" , "column2" => "more data" ));
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" ;
}
}
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" }
