# apc_store

(PECL apc >= 3.0.0)

apc_store — Cache a variable in the data store

### 설명

bool apc_store ( string `$key` , mixed `$var` [, int `$ttl`= 0 ] )

Cache a variable in the data store.

> Note: Unlike many other mechanisms in PHP, variables stored using apc_store() will persist between requests (until the value is removed from the cache).

### 인수

`key`

  Store the variable using this name. `key` s are cache-unique, so storing a second value with the same `key` will overwrite the original value.

`var`

  The variable to store

`ttl`

  Time To Live; store `var` in the cache for `ttl` seconds. After the `ttl` has passed, the stored variable will be expunged from the cache (on the next request). If no `ttl` is supplied (or if the `ttl` is 0), the value will persist until it is removed from the cache manually, or otherwise fails to exist in the cache (clear, restart, etc.).

### 반환값

성공할 경우 `TRUE`를, 실패할 경우 `FALSE`를 반환합니다.

### 예제

Example #1 A apc_store() example

`<?php
$bar = 'BAR';
apc_store('foo', $bar);
var_dump(apc_fetch('foo'));
?>`

위 예제의 출력:

    string(3) "BAR"
