PHP8 APCUIterator 类

(PECL apcu >= 5.0.0)
简介
APCUIterator 类可以更轻松的迭代大型 APCu 缓存。 它所支持的逐步迭代功能对于遍历大型缓存非常有用,每次加锁后只会获取指定数量(默认 100 条)的缓存条目就会释放锁而非一直锁住整个缓存,以便其他活动对缓存进行操作。 此外,使用正则表达式匹配是更高效的,因为它已经被移到了 C 语言层级(C level)。

)
public current(): mixed
public getTotalCount(): int
public getTotalHits(): int
public getTotalSize(): int
public key(): string
public next(): bool
public rewind(): void
public valid(): bool
}
