(PECL quickhash >= Unknown)

QuickHashIntHash::__construct — Creates a new QuickHashIntHash object

### Descripción

public QuickHashIntHash::__construct(int `$size`, int `$options` = ?)

This constructor creates a new QuickHashIntHash. The size is the amount of bucket lists to create. The more lists there are, the less collisions you will have. Options are also supported.

### Parámetros

`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: `QuickHashIntHash::CHECK_FOR_DUPES`, which makes sure no duplicate entries are added to the hash; `QuickHashIntHash::DO_NOT_USE_ZEND_ALLOC` to not use PHP's internal memory manager as well as one of `QuickHashIntHash::HASHER_NO_HASH`, `QuickHashIntHash::HASHER_JENKINS1` or `QuickHashIntHash::HASHER_JENKINS2`. These last three configure which hashing algorithm to use. All options can be combined using bitmasks.

### Valores devueltos

Returns a new QuickHashIntHash object.
