[OpenLayers-Users] How to use WMS, PHP MAPScript and Openlayers (all together :-) )

["tschobber tschöbbi"]

Hi,

thanks for the answer! Ok that's working with a single php file with JUST the following code:

index.php:

---------------------------------------------------
<?php


dl ("php_mapscript.so");

$request = ms_newowsrequestobj();

$request->loadparams();

ms_ioinstallstdouttobuffer();



 $map_path="/srv/www/myParams/";
 $map = ms_newMapObj ($map_path."myMap.map");
 $layer = $map -> getLayerByName("raster");
//$status = $layer->open();
 $layer->set('data', "map_t20000301.png");



$map->owsdispatch($request);

$contenttype = ms_iostripstdoutbuffercontenttype();

if ($contenttype == 'image/png')
      header('Content-type: image/png');

 if ($contenttype == 'EPSG:31297')
       header('Content-type: EPSG:31297');


ms_iogetStdoutBufferBytes();

ms_ioresethandlers();

?>
--------------------------------------------
When I put some html code into index.php my picture is shown in special characters and I get a header warning (see below). Why is this? (if you could have a look at this file I would be very glad --> attached as index.php)

Headerwarning:
---------------------------------------------------
Warning: Cannot modify header information - headers already sent by (output started at /srv/www/htdocs/test.php:7) in /srv/www/htdocs/index.php on line 50
---------------------------------------------------


Secondly how can I create a Layer in Openlayers that calls this index.php file... by just adding a layer like this?: 

var indexlayer = new OpenLayers.Layer.WMS("test","http://localhost/klima/index.php?",{format:'image/png'});

I've tried that, but Openlayers shows me nothing.


thanks for answers!
