You cannot open a new window / new tab using PHP. You must use Javascript to do that. And in the year 2008, it will most-likely be blocked by pop-up blocker.
You will have to use a URL and have the person click on it.
<a href="new_page.php" target="_new">Continue to next page</a>
Simply put, I want to direct the user to the resulting page, based on whatever
choice they have made, and have this new web page open in a new web browser than into the existing browser page from which they made the selection.
Well Ok then.
So if there is no way of doing this with PHP so I guess I will use HTML (JScript) to do it. At least I tried
But FYI, JSP allows for this, and sometimes it is best if not a must that such redirecting of content into a new web browser page should be done by code that was executed server side.
The problem isn’t having PHP return a different page, as this falls within the realm of server-side. The problem is opening a new browser window, which is client-side. I imagine the JSP code you are referring to uses javascript (or some flavor of ECMA) to do so.
