Can't open pdf file downloaded via php header Hi, I am getting some problem to open the pdf file which is downloaded via PHP header.
After download when I try to open this Its give me the error like "Adobe could not open this file either its not supported or file has been demaged it was sent as an email attachment and was not correctly decoded" Can any body help me.
The code I am using that is: PHP Code:.
Just setting a header doesn't make a file that type. Can you open the original file in Adobe? After that, I see that you seem to be missing 2 important headers when using readfile Example 2 Caching directives.
PHP scripts often generate dynamic content that must not be cached by the client browser or any proxy caches between the server and the client browser. Many proxies and clients can be forced to disable caching with:. You may find that your pages aren't cached even if you don't output all of the headers above.
There are a number of options that users may be able to set for their browser that change its default caching behavior.
By sending the headers above, you should override any settings that may otherwise cause the output of your script to be cached. Headers will only be accessible and output when a SAPI that supports them is in use.
You can use output buffering to get around this problem, with the overhead of all of your output to the browser being buffered in the server until you send it.
The HTTP status header line will always be the first sent to the client, regardless of the actual header call being the first or not. The status may be overridden by calling header with a new status line at any time unless the HTTP headers have already been sent.
There is a bug in Microsoft Internet Explorer 4. There is no workaround. There is also a bug in Microsoft Internet Explorer 5. Session ID is not passed with Location header even if session.
It must by passed manually using SID constant. Change language: Edit Report a Bug. Parameters header The header string. Return Values No value is returned.
Changelog Version Description 5. Example 2 Caching directives PHP scripts often generate dynamic content that must not be cached by the client browser or any proxy caches between the server and the client browser. Many proxies and clients can be forced to disable caching with: 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.
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.
Then I have the Content-Length again. 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.
