Yac::__construct — Constructor

Опис

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.

Параметри

prefix

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

Помилки/виключення

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

Приклади

Приклад #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"
?>
