Yac::__construct — Constructor

説明

public function Yac::__construct(string $prefix = "")

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.

パラメータ

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

エラー / 例外

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

例

例1 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"
?>
