如何显示存储在多维数组PHP中的对象的结果

print_r($variable);

var_dump($variable);

<?php
class Person {
    public $name;
    public $age;
}

$person1 = new Person();
$person1->name = "John";
$person1->age = 25;

$person2 = new Person();
$person2->name = "Jane";
$person2->age = 30;

$people = array($person1, $person2);

// 使用print_r()函数显示多维数组中对象的结果
echo "Using print_r():\n";
print_r($people);

// 使用var_dump()函数显示多维数组中对象的结果
echo "\nUsing var_dump():\n";
var_dump($people);
?>

Using print_r():
Array
(
    [0] => Person Object
        (
            [name] => John
            [age] => 25
        )

    [1] => Person Object
        (
            [name] => Jane
            [age] => 30
        )

)

Using var_dump():
array(2) {
  [0]=>
  object(Person)#1 (2) {
    ["name"]=>
    string(4) "John"
    ["age"]=>
    int(25)
  }
  [1]=>
  object(Person)#2 (2) {
    ["name"]=>
    string(4) "Jane"
    ["age"]=>
    int(30)
  }
}
