PHP中的stdClass是什么

用途：

1.stdClass通过调用它们直接访问成员。

2.它在动态对象中很有用。

3.它用于设置动态属性等。

程序1：使用数组存储数据

<?php 
      
// 定义一个数组employee 
$employee_detail_array = array( 
    "name" => "John Doe", 
    "position" => "Software Engineer", 
    "address" => "53, nth street, city", 
    "status" => "best"
); 
  
// 显示内容
print_r($employee_detail_array); 
?>

输出：

Array
(
    [name] => John Doe
    [position] => Software Engineer
    [address] => 53, nth street, city
    [status] => best
)

程序2：使用stdClass而不是数组来存储员工详细信息（动态属性）

<?php 
      
// 定义employee对象样式
$employee_object = new stdClass; 
$employee_object->name = "John Doe"; 
$employee_object->position = "Software Engineer"; 
$employee_object->address = "53, nth street, city"; 
$employee_object->status = "Best"; 
      
// 显示内容 
print_r($employee_object); 
?>

输出：

stdClass Object
(
    [name] => John Doe
    [position] => Software Engineer
    [address] => 53, nth street, city
    [status] => Best
)

注意：可以将数组类型转换为对象，将对象转换为数组。

程序3：将数组转换为对象

<?php 
  
// 
$employee_detail_array = array( 
    "name" => "John Doe", 
    "position" => "Software Engineer", 
    "address" => "53, nth street, city", 
    "status" => "best"
); 
  
// 从数组到对象的类型转换
$employee = (object) $employee_detail_array; 
      
print_r($employee); 
?>

输出：

Array
(
    [name] => John Doe
    [position] => Software Engineer
    [address] => 53, nth street, city
    [status] => Best
)
