Base64 Decode To PDF - Save PDF On Server?

Dec 1, 2009

How can I take a base64 encoded PDF and decode it then save it on my server for linking back to the saved file later? I have searched for some time now on multiple forms and with google, and I have come up empty handed for anything that can even push me in the right direction. Maybe my search terms are poorly constructed, The string that is the base64 encoded pdf comes to me via an xml feed and is dynamically generated through the USPS system. I have tested the encoded strings in 3rd party apps I have found along my search for finding a way to do it with php, and it does work in those.

So if anyone has any experience with this, or can point me towards a decent document (other than the site for the encode manual) that can help me out, or if anyone wants to throw me a demo concept to work with,

.net - C# To PHP Base64 Encode / Decode?

So I have this c# application that needs to ping my web server thats running linux/php stack.
I am having problems with the c# way of base 64 encoding bytes.

my c# code is like:

byte[] encbuff = System.Text.Encoding.UTF8.GetBytes("the string");
String enc = Convert.ToBase64String(encbuff);

and php side:

$data = $_REQUEST['in'];
$raw = base64_decode($data);

with larger strings 100+ chars it fails. I think this is due to c# adding '+'s in the encoding but not sure.

Base64 Decode French Characters?

We are getting base64 encoded (XML) data from a third party. If the XML data is in English, everything works fine, I am able do base64 decode, and parse the XML. If the XML is all lower case French characters, everything works fine. But if the xml data contains upper case French characters (like &Agrave), if I do base64 decode and try to parse it, the parser fails.

Ajax - Flash To Base64 Encode / Decode

I'm using AS3 to base64 encode a JPG and pass it to Javascript. I'm attempting to use AJAX to pass that base64 encoded string to PHP and have PHP decode it. (I know I could send it back to Flash and Flash could decode it and send it to PHP, but I'm trying to eliminate the need for Flash on the decoding end).

It appears that AS3's encodeToBase64String() function and and PHP's base64_decode() function do not use the same algorithm, as PHP evaluates it as a base64 encoded object, but does not seem to output it properly. Is there a way to rectify this problem? Note: Please no posts about not needing Javascript. Javascript is a necessary step for reasons not detailed here.

My major problem is how to download a file from the web and save it into the server by php so that I can open and read it. I would really appreciate any ideas that you professionals might have.

Should I Save Images To The Server

I'm using php to generate pictures, the pictures are maps with different locations plotted on them in different colors to signify information. Right now what the php does is it goes and looks in a mySQL database to get latitude and longitude and information about the location then it draws the location on the map. Right now it does this for every person who goes and looks at the site. I'm wondering if this puts an undue amount of strain on the server and I should look into a way of generating images and then uploading them as flat image files to the server and serving those image files?

So should I make the images every time?

or should I save the images to the server and serve those to the client?

Save A Snapshot Of A SWF To The Server With AS3?

I have explored a few solutions of generating an image serverside with PHP, but they all seem to use a method where the server sends the image to the user. I'm wondering if it's possible to save $GLOBALS["HTTP_RAW_POST_DATA"], which in that example contains the ByteArray sent by Flash, to the server as an image file....

Dl File From Remote URL And Save On Server

I have code using fopen and fread etc that I can tweak, and that I've been tweaking for a while now that will read an image from a specific URL and save on on my server. However, it isn't 100% bug proof and I can foresee problems occuring in the future.

Is there a function or method that will simply download an image/file from a specific remote url and save it to a specific file on my server?
