It depends how the user will get to the php page:
1. Form
If the user is about to submit a form and you want some
Javascript variable from
your page to end up as a php variable after the form is
submitted then:
Create a hidden form variable e.g. <INPUT TYPE=HIDDEN
NAME="myvariable">
Set this formvariable to your Javascript variable in the
Javascript
e.g. document.form.myvariable.value =
myjavascriptvariable;
After submission $myvariable will be a php variable in the
target page with the value you gave it.
2. Link
If you want to set a php variable in a page which the user
will get to by a link,
then you need to add a GET query to the link e.g. your
Javascript will have something like this:
document.myhref.location =
document.myhref.location+"?myvariable="+myjavascriptvariable;
i.e. the link becomes myoriginallink?myvariable=...
php will automatically become up the value you specify and
set $myvariable to that value.
