TokyoTyrant::add — Adds to a numeric key

### Description

public number TokyoTyrant::add ( string `$key` , number `$increment` [, int `$type` = 0 ] )

Adds to an int or double value. This increments the value by the given amount and returns the new value. If the key does not exist a new key is created with initial value of the increment parameter.

### Parameters

`key`

  The string key

`increment`

  The amount to increment

`type`

  `TokyoTyrant::RDBREC_INT` or `TokyoTyrant::RDBREC_DBL` constant. If this parameter is omitted the type is guessed from the `increment` parameters type.

### Return Values

Returns the new value on success

### Examples

Example #1 TokyoTyrant::add() example

`<?php
$tt = new TokyoTyrant("localhost", TokyoTyrant::RDBDEF_PORT);
/* Adds integer 3 to key and creates a new key */
$tt->add("test", 3);
/* String value is converted to double */
echo $tt->add("test", "3.5", TokyoTyrant::RDBREC_DBL);
?>`

The above example will output something similar to:

    6.5
