how to communicate between 2 scripts

[Anon]

I have two php scripts running simultaneously and need to be able to share variables between the two scripts while they are both running. I tried using session variables but it seems like the other script can not access them until the creator script is finished running.

Thanks in advance.

thanks audrus. Anyone else have other suggestions?

1) Write the variables as client-side cookies
2) Write the variables as server-side cookies
3) Write the variables to a database and read them with the other script.

Thanks David.

The problem we face is that more then 1 person may be running this script at once. So all files created by the script must be in a unique directory for that session. Also the 2nd script doesn't know what that unique directory is. So are cookies unique for each session? and would both scripts by default be writing/reading from the same cookie?

I'll try to do either #1 or #2, but I think we'd face a problem with method #3.

thanks again for your help. Is there any more ideas out there? PLEASE HELP 🙂

If you can give some more precise details, I'll have a think. How many people are running how many scripts each? How do you want the scripts to interact? What do the scripts do?

Best,
David

David,

Each person, when they start a session they are running 2 scripts. The 1st script is being called by the broweser through the address bar (i.e. script1.php?sid=23424) and a javascript function calls a function from the 2nd script which all it's doing is returning data. there are three variables that the 2nd script needs to know from the first script at real time. There isn't any interaction really, I just want to be able to see those 3 variables in script 1 so I can return the latest data script 1 is parsing from an xml file.

the purpose of javascript is that it nicely scrolls the data onto the browser.

I hope that's precise enough. thanks.

Hi Vala,

To reconfirm: Script1 calls script2 with parameters. Script2 passes data back to script1 which then formats and displays this data?

How about the following:

script1.php:

<!--Pass the parameter 'mypar1' to script2-->
<script language='javascript' src='script2.php?mypar1=Google'>
</script>
<!-- script2 sets the results variable 'returndata'-->
<script language='javascript'>
alert (returndata);
</script>

script2.php:
<?
// Input: myvar1
// Output: resultvar
echo "returndata='This was the parameter passed: $mypar1';\r";
?>

You can always pass the SID as parameter to script2 if necessary, of course.
Cheers,
David
