MapScript: Adding line between points

[Olli --]

Hellou,

I have the coordinates of three points and I need to add a line from point 1
to point 2 and from point 2 to point 3.

I tried to work with this example and modify to my own code...
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?PHPMapScriptDynamicLine

...but I didn't get it work. Is there any simple solution for this problem?

Thanks.
