What changes need to be made in PHP 7.1.0 for classes and constructors?

In PHP 7.1.0, the way constructors are defined in classes has changed. The old way of defining constructors using the class name is deprecated, and now constructors should be defined using the magic method `__construct()`. To update your classes to be compatible with PHP 7.1.0, simply replace the old constructor definition with `__construct()`.

class MyClass {
    // Old way of defining constructor (deprecated)
    // function MyClass() {
    //     // Constructor code here
    // }

    // New way of defining constructor
    function __construct() {
        // Constructor code here
    }
}
