Deprecation of class name constructors means that you no longer can write OOP code
that works both in PHP 4 and PHP 8 without some hackery.
`This works however`__:

    <?php

    class WorksIn4And8
    {
        var $int;

        // Regular method in PHP 4
        // Constructor in 5-8
        function __construct($int)
        {
            error_log('__construct()');
            $this->int = $int;
        }

        // Constructor in PHP 4
        // Constructor overridden by __construct in 5-7
        // Regular method in PHP 8
        function WorksIn4And8($int)
        {
            error_log('WorksIn4And8()');
            $this->__construct($int);
        }

        function getInt()
        {
            return $this->int;
        }
    }

    $obj = new WorksIn4And8(48);

    var_dump($obj->getInt());
