Hello...
Been testing the new beta release of MS4W (beta3), and i have noticed a strange
behaviour.
I use a small PHP mapscript to generate a picture. But when I use the
mapscriptfunction "set("status", 1)" on a POSTGIS, WMS or WFS layer...the web
browser "hangs" for many seconds before the PHP page is finished rendering.
This behaviour dos not occur when "set("status", 1)" is used on a ESRI SHAPE or
a RASTER layer.
I do not know if this is a mapserver or php thing...? I can even see in my ms
tmp folder that the GIF file is produced...but the webpage "hangs" for many
seconds before it is finished rendered.
Have tested using different web browsers...even using WGET..., so I guess this
behavoiur have something to do with MS or PHP?
PS! This does not occur in MS4W 2.2.3...
I also downloaded MS4W 2.2.4 and the same problem is present there also...
My example PHP looks like this:
<?
//map
$mapObject = ms_newMapObj("mapfile.map");
$mapObject->set("width",1000);
$mapObject->set("height",800);
//Shape - this is OK
$av_digitize_point = $mapObject->getLayerByName("1");
$av_digitize_point->set("status", 1);
//wms - browser hangs!!
//$av_digitize_point = $mapObject->getLayerByName("2");
//$av_digitize_point->set("status", 1);
//wfs - browser hangs!!
//$av_digitize_point = $mapObject->getLayerByName("3");
//$av_digitize_point->set("status", 1);
//raster - this is OK
//$av_digitize_point = $mapObject->getLayerByName("4");
//$av_digitize_point->set("status", 1);
//postgis - browser hangs!!
//$av_digitize_point = $mapObject->getLayerByName("5");
//$av_digitize_point->set("status", 1);
//Draw map image
if (!$mapImage) {
$mapImage = $mapObject->draw();
}
//save image
$mapImage = $mapImage->saveWebImage(MS_GIF,0 ,0,100);
//image url
$mapImage = "http://"; . $SERVER_NAME . $mapImage;
print "<img src=\"".$mapImage."\"/>";
?>
Best Regards
