说明
public QuickHashStringIntHash::__construct

[, int $options = 0

参数
size- The amount of bucket lists to configure. The number you pass in will be automatically rounded up to the next power of two. It is also automatically limited from 64 to 4194304.
options- The options that you can pass in are: QuickHashStringIntHash::CHECK_FOR_DUPES, which makes sure no duplicate entries are added to the hash and QuickHashStringIntHash::DO_NOT_USE_ZEND_ALLOC to not use PHP's internal memory manager.
