<p>Hi,</p>
<p>Thanks for you answer.</p>
<p>I did try " unset($layer->labelitem); " but it didn't work. The layer keep the previous value of " labelitem " when I "unset" it.</p>
<p>I forgot to tell that I use the Version 6.4.1 of MapScript PHP dll.</p>

<p>Hi everyone,</p>
<p>Probably a stupid question but I can't figure it out :</p>
<p>I open a Layer through " <span class="x">$map->getLayer() " and I want to remove " labelitem " and " classitem" parameters.<br /></span></p>
<p><span class="x">I tried to set these parameters to NULL " $layer->labelitem = NULL; " or " $layer->set('labelitem', NULL); " and to empty " $layer->labelitem = ''; " or " $layer->set('labelitem', ''); " but it doesn't remove the " LABELITEM " in the " LAYER " in the MapFile when I save the MapFile " $map->save() ".</span></p>
<p><span class="x">I found that setting an int/double parameter to -1 value removes it (like " maxscaledenom " or " minscaledenom ").</span></p>
<p><span class="x">How can I remove " labelitem " / " classitem " parameters ?</span></p>
<p><span class="x">Thanks a lot for your help !</span></p>
