{Code...} newstatic ($ user); what does it mean ??

php
 public static function findIdentityByAccessToken($token, $type = null)    {        foreach (self::$users as $user) {            if ($user['accessToken'] === $token) {                return new static($user);            }        }        return null;    }

In simple terms, self is written in which class, and actually called is this class. the so-called static binding later, static indicates the class used, that is, the static file you write in the parent class, and then the static file is directly/indirectly used through the subclass, static refers to this subclass, so static is similar to $ this, but static can be used for static methods and attributes.

For example,

class ATest {    public function say()    {        echo 'Segmentfault';    }    public function callSelf()    {        self::say();    }    public function callStatic()    {        static::say();    }}class BTest extends ATest {    public function say()    {        echo 'PHP';    }}$b = new BTest();$b->say(); // output: php$b->callSelf(); // output: segmentfault$b->callStatic(); // output: php

This is the sample paper ~

SimilarselfHoweverstaticKeyword can be used for static binding later. Reference: http://php.net/manual/zh/language.oop5.late-static-bindings.php
