mapscript map loading error

Thu Jul 20 02:14:11 EDT 2006

Hello!

I'd like some help in using PHP/Mapscript. I have a freshly installed
Mapserver machine and is testing some simple php webpages to see if
everything is working, especially PHP/Mapscript:

<?php
	dl ("php_mapscript.so");
	echo("php_mapscript.so loaded.\n");   //to see if the library will
sucessfully load.
	$map_path="/usr/local/apache2/htdocs/recipe1/hello.map";
	echo($map_path);                             // absolute path to the map file
	$map = ms_newMapObj($map_path);
	$image=$map->draw();
	$image_url=$image->saveWebImage();
?>
<HTML>
 <HEAD>
 <TITLE>Mapserver "hello world"</TITLE>
 </HEAD>
 <BODY>
<img SRC="<?php echo $image_url; ?>">
 <p>This is the simplest example I could come up with.</p>
...
</BODY>
</html>

I'm using the following map file. It should produce an image with just
a line of text in it:

MAP
	NAME HELLO
	STATUS ON
	EXTENT 0 0 4000 3000
	SIZE 400 300
	IMAGECOLOR 200 255 255
	WEB
		IMAGEPATH "/usr/local/apache2/htdocs/tmp/"
		IMAGEURL "/tmp/"
	END

	LAYER
		NAME "credits"
		STATUS DEFAULT
		TRANSFORM FALSE
		TYPE ANNOTATION
		FEATURE
			POINTS
				200 150
			END
			TEXT 'Hello world.  Mapserver rocks.'
		END
		CLASS
			LABEL
				TYPE BITMAP
				COLOR 0 0 0
			END
		END
	END

END

The output I'm getting from the browsers is just the following:

                 php_mapscript.so loaded.
/usr/local/apache2/htdocs/recipe1/hello.map

So it seems that everything is working, but only until it encounters
the "$map = ms_newMapObj($map_path);" line. I've checked the tmp
folder I've made to store the images and no images are made (no
surprise there). Would somebody know what the problem might be and
what could be the solution for this? I really, really need to know.

Thanks,
