Question

I have a problem with the extends of PHP. My code in the page.class.php:

    <?php
    require_once ('globals.class.php');
    require_once ('Smarty.class.php');

    class CPage extends Smarty
    {
     .
     .
     .

In the Smarty.class.php the class name is Smarty.

So I don’t know why I get this error:

Fatal error: Class ‘Smarty’ not found in C:\xampp\htdocs\blog\www\classes\page.class.php on line 6

Answer 1

This is more a comment than an actual answer:

As you use require I assume that the Smarty class has been defined.

So you are probably using namespaces, which would require you to use that specific class or provide a fully qualified classname (FQCN) instead:

class CPage extends \Smarty
                    ^- Smarty is in the global namespace in this example

Otherwise use the class on top:

Use \Smarty;

to import it into your current namespace.

The answer is with the pre-condition that the Smarty class you refer to is in the global namespace. I’m not fluent with Smarty so I do not know if it has it’s own namespace yet, and if so, which one it is. So the concrete FQCN might vary.
