I have this code.

<?php

class SomeClass
{
    protected $name;

    public function __construct($name = null)
    {
        if (!empty($name) && is_scalar($name)) {
            $this->name = $name;
        } else {
            $this->name = 'World';
        }
    }

    public function __destruct()
    {
        $this->name = null;
    }

    public function sayHello($name = null)
    {
        if (!empty($name) && is_scalar($name)) {
            $this->name = $name;
        }

        echo 'Hello ' . $this->name . '<br>' . PHP_EOL;
    }
}

SomeClass.php

<?php

require 'SomeClass.php';

$SomeClass = new SomeClass();
$SomeClass->sayHello();

$random = mt_rand(1, 999);

index.php

If I run this code on PHP since 5.5 to7.3 (32 bit) with the latest version of Xdebug, anything cannot be log and Webgrind or QCachegrind can only display SomeClass.php with __destruct() method.
The index.php file did not appears and mt_rand() function also did not appear.
