apcu_add

apcu_add

Cache a new variable in the data store

bool **apcu_add** string $key mixed $var int $ttl

array **apcu_add** array $values mixed $unused int $ttl

Caches a variable in the data store, only if it's not already stored.

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

key Store the variable using this name. s are cache-unique, so attempting to use to store data with a key that already exists will not overwrite the existing data, and will instead return false. (This is the only difference between and .) key``apcu_add``apcu_add``apcu_store

varThe variable to store

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

valuesNames in key, variables in value.

Returns TRUE if something has effectively been added into the cache, FALSE otherwise. Second syntax returns array with error keys.

Voorbeeld: A example

<?php
$bar = 'BAR';
apcu_add('foo', $bar);
var_dump(apcu_fetch('foo'));
echo "\n";
$bar = 'NEVER GETS SET';
apcu_add('foo', $bar);
var_dump(apcu_fetch('foo'));
echo "\n";
?>

string(3) "BAR"
