apcu_store

PHP function Edit on GitHub ✎

(PECL apcu >= 4.0.0)

Cache a variable in the data store

Description

apcu_store(string $key, mixed $var, int $ttl = 0): bool

apcu_store(array $values, mixed $unused = NULL, int $ttl = 0): array

Cache a variable in the data store.

Note

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

key: Store the variable using this name. keys 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.).
values: Names in key, variables in value.

Success Second syntax returns array with error keys.

php

<?php
$bar = 'BAR';
apcu_store('foo', $bar);
var_dump(apcu_fetch('foo'));
?>

The above example will output:

output

string(3) "BAR"
