Yac::__construct

Description

Creates a new Yac instance. The optional prefix is prepended to every key this instance stores, which lets several applications or caches on the same machine use overlapping key names without colliding.

Parameters

prefix

A key prefix, up to 48 bytes (YAC_MAX_KEY_LEN).

Errors/Exceptions

Throws an Exception if the cache is disabled (yac.enable=0), or if prefix is longer than 48 bytes.

Examples

Yac::__construct example

<?php
$yac = new Yac();
$yac->set("foo", "bar");

$other = new Yac("app2_");
var_dump($other->get("foo"));    // bool(false): different namespace
$other->set("foo", "baz");       // stored as "app2_foo"
?>
