Arrays in PHP can contain objects. In PHP, an array is an ordered collection of data that can contain various types of data, including integers, floating point numbers, strings, Boolean values, and objects.

In PHP, an object is a special data type that can be instantiated from a class. A class is a user-defined data structure that defines the properties and behavior of an object. We can create an object by creating an instance of a class and assigning the object to the elements of the array.

Here is a sample code that shows how to use arrays to store objects in PHP:

class Person {
  public $name;
  public $age;
  public function __construct($name, $age) {
    $this->name = $name;
    $this->age = $age;
  }
  public function getDetails() {
    return "Name: " . $this->name . ", Age: " . $this->age;
  }
}
// 创建对象
$person1 = new Person("John Doe", 25);
$person2 = new Person("Jane Smith", 30);
// 创建数组并将对象添加为元素
$people = array($person1, $person2);
// 遍历数组并调用对象的方法
foreach ($people as $person) {
  echo $person->getDetails() . "\n";
}

In the above example, we first define a Person class that has name and age Properties and getDetails method. Then, we create two Person objects $person1 and $person2 and add them to the $people array. Finally, we use a foreach loop to iterate through the array and call the getDetails method of each object to output the object's details.

Therefore, it can be seen that in PHP, array is a very flexible data structure that can accommodate various types of data, including objects. This makes PHP a very powerful and versatile programming language.
