It is a very common error to read code with include , or require , functions, or another file access function, and have spaces or empty lines that are output before header is called. There are two special-case header calls. For example, if you have configured Apache to use a PHP script to handle requests for missing files using the ErrorDocument directive , you may want to make sure that your script generates the proper status code. The second special case is the "Location: Not only does it send this header back to the browser, but it also returns a REDIRECT status code to the browser unless the or a 3xx status code has already been set. The optional replace parameter indicates whether the header should replace a previous similar header, or add a second header of the same type.

All that being said, your code should look more like this: Havenard Havenard You don't need the closing tag? In this case, it's better to remove it.

Notes Note: Most of the pages were displayed correct, but on some of them apache added weird content to it: A 4-digits HexCode on top of the page before any output of my php script , seems to be some kind of checksum, because it changes from page to page and browser to browser.

Several times this one is asked on the net but an answer could not be found in the docs on php. If you want to redirect an user and tell him he will be redirected, e. If not, click here.

So, either you have to use the HTML meta refresh thingy or you use the following: Browsers typically re-request a page every time, cache a page for the session, and cache a page for longer, or even indefinitely.

If the status code is not specified, header 'Location: It seems the note saying the URI must be absolute is obsolete. Found on https: When using PHP to output an image, it won't be cached by the client so if you don't want them to download the image each time they reload the page, you will need to emulate part of the HTTP protocol.

How to Use PHP to Force a File Download

Here's how: If using the 'header' function for the downloading of files, especially if you're passing the filename as a variable, remember to surround the filename with double quotes, otherwise you'll have problems in Firefox as soon as there's a space in the filename.

So instead of typing: Sorry, the site won't let me post such a long link Thanks Rasmus Lerdorf and his team to wrap off parts of unusual php functionality ,php 7 roolez!!!!! It is important to note that headers are actually sent when the first byte is output to the browser.

In the case of redirects, if you forget to terminate your script after sending the header, adding a buffer or sending a character may change which page your users are sent to.

This redirects to 2.

You also won't see any "headers already sent" errors because the browser follows the redirect before it can display the error. This is because headers aren't sent until the output buffer is flushed. Also, be aware that IE versions 5, 6, 7, and 8 double-compress already-compressed files and do not reverse the process correctly, so ZIP files and similar are corrupted on download. The following example disables compression in all versions of IE: BrowserMatch ".

To remedy this you need to call: It will tell the PHP session code to not do any cache header changes of its own. According to the RFC https: You can use HTTP's etags and last modified dates to ensure that you're not sending the browser data it already has cached.

After lots of research and testing, I'd like to share my findings about my problems with Internet Explorer and file downloads. Take a look at this code, which replicates the normal download of a Javascript: Fri, 01 Jan User may change settings. The Content-Length header is required by some browsers to activate download box. I use it here to make sure the box opens.

Anyway, I set the Content-Disposition to attachment because I already know that the box will appear. Then I have the Content-Length again.

Problem with overriding HTTP headers for PDF downloads

Now, here's my big point. Only use the Expires header, after all, it will require the file to be downloaded again the next time. This is not a bug! IE stores downloads in the Temporary Internet Files folder until the download is complete. I know this because once I downloaded a huge file to My Documents, but the Download Dialog box put it in the Temp folder and moved it at the end.

Just think about it. If IE requires the file to be downloaded to the Temp folder, setting the Cache-Control and Pragma headers will cause an error! I hope this saves someone some time!

My files are in a compressed state bz2. When the user clicks the link, I want them to get the uncompressed version of the file. After decompressing the file, I ran into the problem, that the download dialog would always pop up, even when I told the dialog to 'Always perform this operation with this file type'.

As I found out, the problem was in the header directive 'Content-Disposition', namely the 'attachment' directive. If you want your browser to simulate a plain link to a file, either change 'attachment' to 'inline' or omit it alltogether and you'll be fine. This took me a while to figure out and I hope it will help someone else out there, who runs into the same problem. PageRank may be transferred. The new URI is not a substitute reference for the originally requested resource and is not cached.

Otherwise you will face problem of headers not being properly sent eg. Cannot modify header information - headers already sent by output started at C: Just to inform you all, do not get confused between Content-Transfer-Encoding and Content-Encoding Content-Transfer-Encoding specifies the encoding used to transfer the data within the HTTP protocol, like raw binary or base Eg Use: If you want to remove a header and keep it from being sent as part of the header response, just provide nothing as the header value after the header name.

For example PHP, by default, always returns the following header: Fri, 16 Oct I just want to add, becuase I see here lots of wrong formated headers. All used headers have first letters uppercase, so you MUST follow this.
