PHP_SELF and IIS

[barand]

I've just transferred an application to IIS and strange things happening.

A.php
a form with two submit buttons.
Button B calls header("location: B.php")

B.php
a form action=$PHP_SELF to validate contents.
on submit, goes to A.php !!

Change 'action = $PHP_SELF' to B.php and it works.

(Using $_SERVER['PHP_SELF'] gives same results.)

So the question is why, in B.php, is $PHP_SELF==A.php?

I'm not entirely sure since this has never happened to me, but I would guess from what you said that an HTTP redirect would cause the $SERVER['PHP_SELF'] to carry over to the script it redirects to, since I know $SERVER['HTTP_REFERER'] does this.

Ive done a bit of experimenting and using

echo "<META HTTP-EQUIV=\"Refresh\" CONTENT=\"0;URL=B.php\">";

in A.php to transfer to B.php instead of the header() function works.

Looks like this could be a "feature" of PHP's header function.
