[GIS] GEOSERVER and Php

geoserverPHP

I want to use a Php script to retrieve information from the .db file of a shapefile saved as a layer in Geoserver. I need to retrieve attribute data from the layer and present it at the client side.

Is this possible with the functionality provided by the geoserver?

yes it is very possible and called web feature service, you can make wfs requests to geoserver with curl library and pass that information to your client. data from geoserver is served as GML,JSON etc. you need to parse this information

[GIS] How to transform/convert Coordinate Reference System with Proj4 and php

Yes you can get them to work together. Below is a sample of code from a php page I coded that uses proj4js, mine is slightly different going from a state plane into wgs84 but the concept is the same. (The syntax is a little off as I had problems pasting it into a code block and my code is sort of spread all over the place in a couple php files but I think you can follow the logic)

enter code here

require_once "config.php";
   foreach ($zones as $id => $zone) {
     $zone_selector .= '<option    value="'.$id.'">'.$zone['name'].'</option>';}
if ($_REQUEST['zone']) {
    $zone_id = $_REQUEST['zone'];
    $zone_name = $zones[$zone_id]['name'];
    $zone_vars = $zones[$zone_id]['vars'];}
if (!$zone_name) $zone_name = "State Plane Coordinates Converter";

points = new Array();
noaa_points = new Array();
var p;
var thispoint;

Proj4js.defs["'.$zone_id.'"] = "'.$zone_vars.'";

var dest = new Proj4js.Proj("EPSG:4326");  /* Lat and Lon projection */
var source = new Proj4js.Proj("'.$zone_id.'");


if ($_REQUEST['n'] && $_REQUEST['e']) 
{echo '
p = new Proj4js.Point('.$_REQUEST['e'].','.$_REQUEST['n'].');
Proj4js.transform(source,dest,p);
points.push({num:1,north:"'.$_REQUEST['n'].'",east:"'.$_REQUEST['e'].'",zone:"'.$zone_name.'",elev:0,desc:"Single Converted Point",lat:p.y,lng:p.x,noaalat:0,noaalng:0});

[GIS] OpenLayers 2.1x load WMS layers from PHP

Yes, it is possible. But what is the source of layer list? If that information is stored in a some kind of database, then PHP will be the right way. But when you want to load all layers from WMS server/workspace, then AJAX call to GetCapabilities or GeoServer API will be better. Last but not least, if layer list is immutable, this could be done entirely in JavaScript. If you provide some details about the layer list source, I'll post some code examples.
