How to make Moving Symbols using MapScript

[vdharan]

Hello,
Iam working on a vehicle tracking system. I want to show symbols
representing vehicles to move in the map as and when the co-ordinate of the
vehicle changes. I continuously get the co-ordinate of the vehicles at
regular intervals. I want this to happen without refreshing the page.

Can any one suggest me a way to do this.
Iam using Redhat9 and PHP Mapscript.

Best Regards,
vdharan
