You are giving $template when you create an $Contenido object.

new Plantilla('el codigo es {CODIGO_RANDOM}');

You mean it to be set as local property of class. But the construction function in PHP calls not by class name, but with special name __construct()

The code of class should start with the following

class Plantilla
{
    function __construct($template_file)      //<-- this function name changes
    {
        $this->tpl_file = $template_file;
    }
}

Please, follow this manual: https://www.php.net/manual/en/language.oop5.decon.php
