C++ allow inline initialisation

As a PHP developer, I was greatly surprised when discovering, while learning C++, the inline initialisation process

Using PHP 7, you would start a class for example with :

/**
 * Class User
 * @package
 */
class User {
    /**
     * @var int $id
     */
    private int $id;

    /**
     * @var string $name
     */
    private string $name;

    /**
     * User constructor.
     *
     * @param int $id
     * @param string $name
     */
    public function __construct(int $id, string $name) {
        $this->id = $id;
        $this->name = $name;
    }
}

Using C++, same class would become

user.h

#ifndef USER_USER_H
#define USER_USER_H

#include <iostream>


class User {
private:
    /**
     *
     */
    int m_id;

    /**
     *
     */
    std::string m_name;
public:
    /**
     * Constructor
     * @param id
     * @param name
     */
    User(int id, std::string name);
};

#endif //USER_USER_H

user.cpp

#include "user.h"

User::User(int id, std::string name) : m_id(id), m_name(name) {
    // Other logic in constructor
}

The inline initialization takes place where nowadays in PHP you would specify return type. Using this notation, you clearly light up constructor method body.
