preg replace (again -.-)

[quote author="Don Robin." date="1218223256"]Hi!
PHP function preg_replace seems to be something which I'll never completely understand, I suppose
Here's the code:

Code:

$layout = preg_replace('~{(.+?)}~', '<div class="$1">'.$this->replace('$1').'</div>', $layout);

I have to replace everything which looks like this:

Code:

{some}

to this:

Code:

<div class="some"> stuff </div>

The problem appears because inside the div tag I have to print something which depends from what I have inside the brackets, but I can't pass the variable '$1' in my method $this->replace() becauase PHP sees it as just "$1".
Where's my mistake? Can't found it :-(
Thank you, in advance, guys. [/quote]

remove the '' from '$1' in replace('$1') ...

Code:

$layout = preg_replace('~{(.+?)}~', '<div class="$1">'.$this->replace($1).'</div>', $layout);
