CollectionFind::offset — Skip given number of elements to be returned

### 说明

public mysql_xdevapi\CollectionFind::offset(int `$position`): mysql_xdevapi\CollectionFind

Skip (offset) these number of elements that otherwise would be returned by the find operation. Use with the limit() method.

Defining an offset larger than the result set size results in an empty set.

### 参数

`position`

  Number of elements to skip for the limit() operation.

### 返回值

A CollectionFind object that can be used for additional processing.

### 示例

示例 #1 mysql_xdevapi\CollectionFind::offset() example

`<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();
$schema = $session->getSchema("addressbook");
$create = $schema->createCollection("people");
$create
->add('{"name": "Alfred", "age": 18, "job": "Butler"}')
->execute();
$create
->add('{"name": "Reginald", "age": 42, "job": "Butler"}')
->execute();
// ...
$collection = $schema->getCollection("people");
$result = $collection
->find()
->sort('age asc')
->offset(1)
->limit(1)
->execute();
var_dump($result->fetchAll());
?>`

以上示例的输出类似于：

    array(1) {
      [0]=>
      array(4) {
        ["_id"]=>
        string(28) "00005b6b536100000000000000f3"
        ["age"]=>
        int(42)
        ["job"]=>
        string(6) "Butler"
        ["name"]=>
        string(8) "Reginald"
      }
    }
