# apc_store

(PECL)

apc_store -- Cache a variable in the data store

## Beschreibung

bool apc_store ( string key, mixed var [, int ttl] )

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

## Parameter Liste

`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.).

## Rückgabewerte

Gibt bei Erfolg `TRUE` zurück, im Fehlerfall `FALSE`.

## Beispiele

Beispiel 1. A apc_store() example

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

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    string(3) "BAR"
