CakePHP and DefaultPasswordHasher syntax error - cakephp-3.0

Question

I have no clue why but for the line
use Cake\Auth\DefaultPasswordHasher;
I'm getting an error
Error: syntax error, unexpected '?'
and full code of user.php
namespace App\Model\Entity;
use Cake\ORM\Entity;
use Cake\Auth\DefaultPasswordHasher;
/**
* User Entity
*
* #property int $id
* #property string $email
* #property string $password
* #property \Cake\I18n\Time $created
* #property \Cake\I18n\Time $modified
*
* #property \App\Model\Entity\Bookmark[] $bookmarks
*/
class User extends Entity
{
/**
* Fields that can be mass assigned using newEntity() or patchEntity().
*
* Note that when '*' is set to true, this allows all unspecified fields to
* be mass assigned. For security purposes, it is advised to set '*' to false
* (or remove it), and explicitly make individual fields accessible as needed.
*
* #var array
*/
protected $_accessible = [
'*' => true,
'id' => false
];
/**
* Fields that are excluded from JSON versions of the entity.
*
* #var array
*/
protected $_hidden = [
'password'
];
protected function _setPassword($value){
$hasher = new DefaultPasswordHasher();
return $hasher->hash($value);
}
}
Any thoughts? I'm using latest CakePHP

Answer 1

Please try with this one. Please update your CakePHP project with composer, it will update all dependency if you miss something.
namespace App\Model\Entity;
use Cake\Auth\DefaultPasswordHasher;
use Cake\ORM\Entity;
class User extends Entity
{
// Make all fields mass assignable except for primary key field "id".
protected $_accessible = [
'*' => true,
'id' => false
];
// ...
protected function _setPassword($password)
{
return (new DefaultPasswordHasher)->hash($password);
}
// ...
}
Also please read this doc here. Hope it should be help you to solve this issue.
