Question

Iam很难用属性对一组对象进行分组。我无法在这个问题上找到一个好的答案;可能是我累了;可能是我错过了这里必不可少的东西。无论如何 - 我创建了一个包含员工对象的Employee类。包括姓名，电子邮件，电话和部门。我想按部门对我的员工进行分组。因此，如果我打印出我的阵列，那么每个销售人员都会聚在一起。

现在看起来像是什么：

 $employees = array();
     while ($loop->have_posts() ) : $loop->the_post();

    $data = array(
    'name' => get_post_meta(get_the_ID(), 'prefix_name', true),
    'email' => get_post_meta(get_the_ID(), 'prefix_mail', true),
    'phone' => get_post_meta(get_the_ID(), 'prefix_phone', true),
    'department' => get_post_meta(get_the_ID(), 'prefix_department', true)
    );
    array_push($employees, new Employee($data));
endwhile;

员工类：

class Employee
{

public $name;
public $email;
public $phone;
public $department;


public function __construct(Array $params = array()){
    if(count($params)){
        foreach($params as $key => $value) {
            $this->$key = $value;
        }
    }
}

}

$employees需要是一个关联数组，将各个部门作为其关键字。

像这样：

$employees = array();
while ($loop->have_posts() ) : $loop->the_post();

    $data = array(
      'name' => get_post_meta(get_the_ID(), 'prefix_name', true),
      'email' => get_post_meta(get_the_ID(), 'prefix_mail', true),
      'phone' => get_post_meta(get_the_ID(), 'prefix_phone', true),
      'department' => get_post_meta(get_the_ID(), 'prefix_department', true)
    );

    // Check if there is already an index for this department, or create it
    if(!isset($employees[$data['department']])) {
        $employees[$data['department']] = array();
    }

    // Assign the employee object to that key (department)
    $employees[$data['department']][] = new Employee($data));

endwhile;

PHP对象数组 - 按属性分组
