Daniel,

thanks for the answer. Sorry, I guessed that the info indicated on the page 
means that the bug was resolved, but wasn't sure. And the problem using 
your suggested method I still get "0" values. But I found a slightly 
different way.

[....]

// draw legend
$image_legend = $map -> drawLegend();
$url_legend = $image_legend -> saveWebImage(MS_PNG, 1, 1, 0);

// calculate height
$legHeight = $image_legend -> height;  //----> works fine
$legHeight = $map -> legend -> height; //-----> does not work

Yes they are accessible using $map->legend->width and<br>
$map->legend->height.  They've been there since 2001-10-17
according to<br>
the bug report that was mentioned in the list message above.<br><br>
