I' ve declared a class HtmlPage and a class HtmlSubPage that extends HtmlPage.
In HtmlPage I use an array and in HtmlSubPage I want to adjust it.

look at this sample of my code:

class HtmlPage{

//more declarations
public $styles;
public function __construct(){

//<!-- HtmlPage_constructor -->'
//more initialisations
$this->styles = array( array('href'=>'css/layout.css', 'media'=>'screen'));

}

}

class HtmlSubPage extends HtmlPage{

private $type;
private $path; //Path to main dir!

public function __construct($kind){

parent::__construct();
$this->type=$kind;
$this->path='../';
foreach($this->styles as $item)

$item['href']=$this->path.$item['href'];

//this has no effect in the html, but if I echo directly "$this->path.$item['href'];" then it outputs normal (../css/layout.css).

}
Has anyone got a clue how this is possible?

The complete source code is in the attached zip file!

what exactly do you want to achive?

I want to generate my html dynamically, the structure of my website is 1 root site and many subsites (like an foldersystem).
The class HtmlPage creates an root-page, the class HtmlSubPage creates an sub-page...
But there are some properties that stay the same for any page (CSS, footer-images, Javascript files to include) and its that path that is stored in the array.

But the weird thing was:

when I write:

PHP Code:

foreach($this->styles as $item)

   echo '<!-- '.$this->path.$item['href'].'-->'; 

I get the expected outcome,but when I write:

PHP Code:

foreach($this->styles as $item)

   $item['href']=$this->path.$item['href']; 

Then none of the items in the array have been adjusted.

So the question is actually this:
Why isn't the value assigned to the array-item?

Hello,

This is because in this loop:
foreach($this->styles as $item)
$item['href']=$this->path.$item['href'];

the $item is a copy of the actual variable in the array. You must use key=>value pair in the loop:

foreach($this->styles as $k=>$item) {
$this->styles[$k]['href'] = $this->path . $this->styles[$k]['href'];
}

Also you could opt to use PHP5's
foreach($this->styles as &$item) {
$item['href']=$this->path.$item['href'];
}

but this breed of foreach had (or still has) errors: http://bugs.php.net/bug.php?id=31118
