One example:

PHP код:

myobject = CreateObject(19371, X, Y, Z+0.5, 0.0, 0.0, 0.0, 300.0);
SetObjectMaterial(myobject, materialindex, modelid, txdname[], texturename[], materialcolor); 


Second example:

PHP код:

SetObjectMaterial(CreateObject(19371, X, Y, Z+0.5, 0.0, 0.0, 0.0, 300.0), materialindex, modelid, txdname[], texturename[], materialcolor); 


As first param "objectid" you can't use ID of object just, it is meant for created object ID (createobject...).
