范例

Example #1 TokyoTyrantTable::putCat() example

<?php

$tt  = new  TokyoTyrantTable ( "localhost" 1979 );


$index  $tt -> put ( null , array( "column1"  =>  "some data" "column2"  =>  "more data" ));


var_dump ( $tt -> get ( $index ));


$tt -> putcat ( $index , array( "column1"  =>  "something new" "new_column"  =>  "other data" ));


var_dump ( $tt -> get ( $index ));
?>

以上例程会输出:

array(2) {
  ["column1"]=>
  string(9) "some data"
  ["column2"]=>
  string(9) "more data"
}
array(3) {
  ["column1"]=>
  string(9) "some data"
  ["column2"]=>
  string(9) "more data"
  ["new_column"]=>
  string(10) "other data"
}
