An object is an individual instance of the data structure defined by a class. We define a class once and then make many objects that belong to it. Objects are also known as instances.
In this article, we will create an object without using a class in PHP.
Using new stdClass() to create an object without class: For creating an object without a class, we will use a new stdClass() operator and then add some properties to them.
Syntax:
// Creating an object $object = new stdClass(); // Property added to the object $object->property = 'Property_value';
Example1: The following code demonstrates the new stdClass() method.
PHP
<?php // Create an Object $object = new stdClass(); // Added property to the object $object->name = 'neveropen'; $object->address = 'Noida'; // Print the object print_r($object); ?> |
stdClass Object
(
[name] => neveropen
[address] => Noida
)
Convert an array into an object without class: We will create an associative array with the list of keys and values, and after that, we use typecast to convert the array into an object.
Syntax:
// Declare an array
$arr = array(
key1 => val1,
key2 => val2,
...
);
// Typecast to convert an array into object
$obj = (object) $arr;
Example 2: The following code demonstrates the conversion of an array into an object without a class.
PHP
<?php // Create an associative array $studentMarks = array( "Biology"=>95, "Physics"=>90, "Chemistry"=>96, "English"=>93, "Computer"=>98 ); // Use typecast to convert // array into object $obj = (object) $studentMarks; // Print the object print_r($obj); ?> |
stdClass Object
(
[Biology] => 95
[Physics] => 90
[Chemistry] => 96
[English] => 93
[Computer] => 98
)
