What is stdClass in PHP

stdClass is an empty class in PHP used to convert other types to objects. It is similar to a Java or Python object. stdClass is not the base class of objects. If you convert an object to an object, it will not be modified. However, if you convert/type the object type, an instance of stdClass is created if it is not NULL. If NULL, the new instance will be empty.

Purpose:

1.stdClass directly access members by calling them.

2. It is useful in dynamic objects.

3. It is used to set dynamic properties, etc.

Program 1: Use array to store data

<?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); 
?>

Output:

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

Program 2: Use stdClass instead of array to store employee details Information (Dynamic Properties)

<?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); 
?>

Output:

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

Note: You can convert array types to objects and objects to arrays.

Program 3: Convert array to object

<?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); 
?>

Output:

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