PHP provides several methods to convert object data into an array. Here are a few ways to accomplish this:
Using Type Casting
Type casting an object to an array is a simple and direct approach:
// Define a sample class
class Sample {
public $property1 = 'Value 1';
public $property2 = 'Value 2';
}
// Create an instance of the class
$object = new Sample();
// Convert object to an array using type casting
$array = (array) $object;
// Output the resulting array
var_dump($array);
Using get_object_vars()
The get_object_vars() function retrieves all the properties of an object as an associative array:
// Define a sample class
class Sample {
public $property1 = 'Value 1';
public $property2 = 'Value 2';
}
// Create an instance of the class
$object = new Sample();
// Convert object properties to an array using get_object_vars()
$array = get_object_vars($object);
// Output the resulting array
var_dump($array);
Using JSON Serialization
Another method involves converting the object to JSON format and then decoding it back to an associative array:
// Define a sample class
class Sample {
public $property1 = 'Value 1';
public $property2 = 'Value 2';
}
// Create an instance of the class
$object = new Sample();
// Convert object to array using JSON
$array = json_decode(json_encode($object), true);
// Output the resulting array
var_dump($array);
Note:
- When type casting or using
get_object_vars(), only public properties will be converted to an array. Private and protected properties won’t be accessible. - Using JSON serialization might not be efficient for complex nested objects or objects containing non-serializable data types.
