Yes, see the file() function. It works on http requests too, even though it's grouped with filesystem functions.

To create a link to the previous page you can use the <pre> getenv("HTTP_REFERER") </pre> command and set it up as a hyperlink. You might also want to put a IF condition on it so it won't get displayed if the user has gone straight in to the page.

To display the current URL, I'd rather use <PRE>$REQUEST_URI</PRE> or <PRE>$SERVER_NAME.$REQUEST_URI</PRE>. This will include the query-string.

does anyone know how to redirect the user to another page?
rob@OhReally.com
To redirect your visitors without interference (no warning/explanation) you should use <PRE>header("Location: http://some.server.com");</PRE>

Hey, I'm looking for a function that can return a directory listing of a website just as if you went to a page with no index. Any help would be great.

Is there a way to trap error or warning messages from the browser so that I can display my own?
paul@honeylocust.com
Is there any way I can know if it's legal to send a Header() at any particular time? I'm writing an error handling function that will redirect the user to a new page if the error happens before any information has been output -- but sends a message with die() otherwise.

I need to parse a response from a webserver over https. A simple fopen statment seems to be close to what im looking for, however the default method is a GET request, where I must have a POST request. In short.. i need to post variables to a script on another server and then process its response.

I have a table showing results from a Mysql database. There are 4 columns. Now my problem is that on clicking on a particular row of any column it should send a value to the calling program to open another page.
jfbolus@m3com.com
I've got a problem with Internet Information Server 4.0. Lets say, for example, I send header("HTTP/1.0 404 Not Found"). When I go to the page, I should get a 404 Not Found error right? Apparently not, cause it doesn't happen. This is the header information that IIS sends when I make a request for that page.
mkhenry@sympatico.ca
Does anyone know how I can pick-up where an http request wants to go, and then based on that information, load their page?
