How i can transfer variable to PHP from javascript(javascript is intro PHP)?

I guess what you're doing (screen resolution?) ...

Your javascript will EITHER have to reload some page sending the data via querystring (script.php?width=123&height=234) - look at location in the javascript reference.

OR, you can set a cookie with javascript. cookies can be read by php scripts, too.
(setcookie functions)

browse through the javascript object reference a bit.

I have a list with checkboxes, if you click the first one, all the other are checked with the following javascript function:
function selectall() {
for (i=1;i<=20;i++) {
document.msgform.msg.checked=
document.msgform.msg[0].checked;
}
}
problem is, if i want to submit the form, an have the value's of my checkboxes in an array, the name of my checkboxes had to end with [], otherwise it isn't an array.
but javascript doesn't like this, what should i change in my javascript function to check al the checkboxes(20) with name="msg[]"
??
Thanks in advance,
Bruno
