Can you instantiate an object and call a method in one line in PHP?

Instantiating Objects and Calling Methods in a Single Line in PHP

In PHP, one would typically instantiate an object and then call a method on it using separate lines of code. However, a common question arises: is it possible to combine these steps into a single line?

Question: Can an object be instantiated and a method called in the same line in PHP?

Answer: Yes, this feature became available in PHP 5.4. The syntax for this operation is:

$method_result = (new Obj())->method();

This allows you to instantiate an object, represented by Obj(), and immediately access one of its methods, method(), assigning the result to the variable $method_result.

Details:

The introduction of this feature in PHP 5.4 addressed requests for a more concise and convenient way to instantiate objects and access their methods. Prior to PHP 5.4, it was necessary to declare the object and then separately call its method:

$obj = new Obj();
$method_result = $obj->method();

The new syntax streamlines this process, providing a more efficient and readable approach for PHP developers.
