php mysql javascript refresh problem, please help...

[munky69]

Hi,  Firstly I am a bit new to this, got a project to do and spent the last month or so trying to develop a googlemaps application using mysql to store the information, php to retrieve it and return the results in xhtml  ? using document.createElement.

This list is read by javascript and used in googlemaps.

 

This is all working but the information in the database changes rapidly so i need to on a timed basis(every 60 secs) do the php query and the javascript update markers. Can't refresh the whole page as it would increase  hits to googlemaps and reset the start location.

 

I have tried using the php sleep for the php, found that it buffered the output, included the @ob_flush(); But i still have php has taken longer than 30 secs to execute problem.

 

I was going to try javascript setinterval to update the markers from the xhtml.

 

Am i going about things all wrong?? would i be better using <meta http-equiv="refresh" to do something?

 

ANY HELP WOULD BE REALLY APPRECIATED

 

Thanks,
