using "include" for different directories

[bazaarboy]

ok so I'm trying to generate a graph with pchart and then email it with phpmailer

the script to generate the graph works fine, and contains the lines:

include("pChart/pData.class");  

include("pChart/pChart.class"); 

... and the script that sends the emails has:

include_once("class.phpmailer.php");

I run both scripts from one parent script that is trying to generate the graph and send the emails - the problem is if the parent script is places in the pchart folder the phpmailer script produces errors, and if I put the parent script in the phpmailer folder the pchart script produces errors

how can I specify to each of the scripts how they should respect their own respective "include" paths?? do I need to use the "exec" function??

thanks!!

how about something like this:

/parent file
/pChart/FILES
/phpmailer/FILES

in parent script

include("pChart/pChart.class"); 
include("phpmailer/class.phpmailer.php");
