PHP edition at Beginning Google Maps Applications

PHP edition

We tried our best but here are the little things we missed:

Listing 2-8: In some printings of the book the parameters to addMarker function are (lonigtude, latitude, description) however the correct order is (latitude, longitude, description). The downloadable source code is correct.

Listing 3-1 and 3-2: There is an erroneous 2 in map.addControl(new GMap2TypeControl()); where it should be map.addControl(new GMapTypeControl());
Listing 3-6: When creating the MARKER XML node, there shouldn’t be a \n at the end of the line.
Listing 3-6: The input should be properly encoded and escaped:
$found = htmlspecialchars(strip_tags(utf8_encode($_GET[’found’])));
$left = htmlspecialchars(strip_tags(utf8_encode($_GET[’left’])));
$icon = htmlspecialchars(strip_tags(utf8_encode($_GET[’icon’])));
Listing 3-8: There is a missing semi-colon after retrieveMarkers()

Google Geocoding 403: With Google’s Geocoding rate limiting you’re required to make a request to the server no more frequently than once every 1.75 seconds. The source code for this chapter had usleep(175000) but it should have been usleep(1750000). This has been corrected in the downloadable code on this site.

Problems with GPoint: A little GMap/GMap2 incompatibility crept into Chapter 6, and affects Listing 6-14 and Listing 6-15. In both cases, new GPoint(pointData.longitude, pointData.latitude) should changed to new GLatLng(pointData.latitude, pointData.longitude).

Listing 9-9: When creating the copyright block, the line copyrights.addCopyright(visibleEarth); should be outside the closing brace of the New GCopyrightCollection();
