Variable Pass

[EchoFool]

Hey,

 

I have been trying to find a simple demo script for passing variables with ajax but to no avail any has really made any sense to me.

 

I was wondering if some one could simple show a crude example of how to send a variable from a php script to a different php script and return it.

 

For example:

 

PHP1 script:Send $Var to PHP2PHP2 script:

Assign to $Var2 do some processingSend $Var2 back to PHP1

 

Can some one please show me a simple example so i can fiddle with and learn from it.

 

Thanks

This is a very simple example written by the guy who first wrote php.

 

You would however be much better off using a framework such as jQuery these days.

Oh i did not know jquery did it also... which is easiest/server efficient (if the script in question is calling a php script every half a second)

 

To give idea of what im doing im trying to build a live chat with ajax (which is already working) as it calls a script which loads out the logs but currently it does not do any checks if there are new messages, as i only want it now to call if there are new messages which will add to server efficientcy.
