O am creating a record of sites, the process data in php and mysql, and s开发者_如何学Goaved to XML. Everything works fine, but I could not get setMap function () hide the markers arranged by type.

That's probably because you are calling the function on the array:

markersArray.setMap(null); 

You have to call the function for each marker in the array! ;)
