adding label to point layer in PHPMapscript

[Pietro Giannini]

Dear Murat,

the code is ok, the problem seems to be the 'labelitem'

>  $koyadi="deneme";
>  $point_layer->set("labelitem","$koyadi");

If I set this property the label don't shows,
if I don't set the label shows.

I believe the MS override the labels of the features if we set the label
for the shapes; there is a little difference between 'shape', which is a
geometry joined with a record on a table, and 'feature', which is only a
geometry with, if requested, a label.

Whith the function $layer->addFeature($shape) we add a feature to the layer.

Try & let me know

regards
Pietro
