Create a class and a style like eg:
$oClass = ms_newClassObj($oLayer);
$oStyle = ms_newStyleObj($oClass);
$aColor[0] = 0;
$aColor[1] = 0;
$aColor[2] = 0;
$oStyle->color->setRGB($aColor[0], $aColor[1], $aColor[2]);
And set the expression of the class with set Expression:
$oClass->setexpression( '([id] = '.$aRec['id'].')' );
Best regards,
Bart

Subject: [UMN_MAPSERVER-USERS] PHP/MapScript: How to change the color of a
point?
This is what I do to draw a point:
$point = ms_newPointObj();
$point->setXY($x,$y);
$line = ms_newLineObj();
$line->add($point);
$feature = ms_newShapeObj(0);
$feature->set("text"," ");
$feature->add($line);
$layer = $map->getLayerByName($layer_name);
$layer->addFeature($feature);
What I need is to change the color of the point (RGB) according to some
condition, can anyone help me?
Alexandre.
