TokyoTyrantTable::putCat — Concatenates to a row

说明

public TokyoTyrantTable::putCat ( string $key , array $columns ) : void

参数

key: The primary key of the row or NULL
columns: Array of row contents

返回值

Returns the primary key and throws TokyoTyrantException on error.

范例

Example #1 TokyoTyrantTable::putCat() 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));

/* Modify an existing row */
$tt->putcat($index, array("column1" => "something new", "new_column" => "other data"));

/* Get the row back */
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"
}
