Description:
------------
The comments for Example 1 at http://www.php.net/manual/en/language.oop5.interfaces.php appear to be technically incorrect.

The comment states:
"// Fatal error: Class BadTemplate contains 1 abstract methods
// and must therefore be declared abstract (iTemplate::getHtml)"

When I copy & paste the entire example into a text editor and 'Search' for the word 'abstract', the only two places it appears are in the comment as noted above.

This also means iTemplate::getHtml is not declared 'abstract'.

Declaration of Template::getHtml:
    public function getHtml($template)

The only way it seems the comments can be correct are if declaring an interface automatically makes those functions or methods, abstract.  There is no such mention of this, that I could find, at the specified URL.


Test script:
---------------
URL: http://www.php.net/manual/en/language.oop5.interfaces.php

// This will not work
// Fatal error: Class BadTemplate contains 1 abstract methods
// and must therefore be declared abstract (iTemplate::getHtml)
class BadTemplate implements iTemplate
{
    private $vars = array();
  
    public function setVariable($name, $var)
    {
        $this->vars[$name] = $var;
    }
}
?>


Expected result:
----------------
// This will work
// No error: because there is no method or function explicitly declared 'abstract' in this example.
{
    private $vars = array();
  
    public function setVariable($name, $var)
    {
        $this->vars[$name] = $var;
    }
}
?>
