# Memcached::deleteByKey

(PECL memcached >= 0.1.0)

Memcached::deleteByKey — Delete an item from a specific server

### Description

public bool Memcached::deleteByKey ( string `$server_key` , string `$key` [, int `$time` = 0 ] )

Memcached::deleteByKey() is functionally equivalent to Memcached::delete(), except that the free-form `server_key` can be used to map the `key` to a specific server.

### Parameters

`server_key`

  The key identifying the server to store the value on or retrieve it from. Instead of hashing on the actual key for the item, we hash on the server key when deciding which memcached server to talk to. This allows related items to be grouped together on a single server for efficiency with multi operations.

`key`

  The key to be deleted.

`time`

  The amount of time the server will wait to delete the item.

### Return Values

Returns `TRUE` on success or `FALSE` on failure. The Memcached::getResultCode() will return `Memcached::RES_NOTFOUND` if the key does not exist.
