Read Binary File Containing UDP Packets?

I have a program which listens to some udp packets being sent by other programs and saves it to a file. I need to make a parser in php to ready in the information which was captured from the other program which was listening.

I am attempting to use un_pack to get the UDP header, from which I could get the contents, but the ports and length headers do not match up with the current logs that the program is giving me so I think I am doing something wrong. I am kinda new to this kind of stuff, but bellow is what I have going on.

$i = 0;
$sourceport = unpack("S", $content[$i++].$content[$i++]);
$targetport = unpack("S", $content[$i++].$content[$i++]);
$length = unpack("S", $content[$i++].$content[$i++]);
$checksum = unpack("S", $content[$i++].$content[$i++]);

Oh and one more thing, I don't really know how to parse the data, will it just be in plain text or will I need to do something else with it?

Read A Binary File In Java?

I have a java program that stores a byte array of 128 bytes length in a MySQL "BINARY (128)" field.

Then, with PHP I access to the database and I give the option to export this data into a file, so I unpack() the binary data, and write it into a file.

This file then, has to be read in a Java program that I am writing, but I can't find how I have to read this data. Any suggestion?

I tried with:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
int i = 0;
while (i < 128) {

But returns an int, and the byte array I sent to the mysql db was a string:

Outputting A Binary File As A Javascript Binary String?

I have a binary file (the type doesn't matter) that I have opened in PHP. I want to be able to output the data from PHP to a Javascript variable, ie, a binary string. For a comparison and proof of possibility, if you set a XmlHttpRequest's override mime type to text/plain and charset of user-defined, you can force the full binary file to be loaded as a binary string and then access that in javascript world.

I am unable to use ajax and therefore need to be able to output that same data directly from a PHP script. After correctly escaping all javascript related data such as quotes, backslashes and newlines as well as aligning it to UTF-16, The browser will complain about an illegal character inside the string while parsing. Therefore I have missed a character that I need to escape (probably).

Read A Binary String In C#?

There is a php script which sends a binary string to the client application:

$binary_string = pack('i',count($result_matrix));
foreach ($result_matrix as $row)
foreach ($row as $cell)
$binary_string .= pack('d',$cell);


Silverlight application receives $binary_string via POST protocol. How can I parse this binary string?

Or maybe there is a better way to send matrix from PHP to Silverlight?

File Download Problem - Change A Binary File Into A Text And Open It In A Browser

I have uploaded files to mysql (doc and xls) using the tutorial. The problem comes when I try to download. Again I followed instructions in the tutorial. When I click on the link to download the file, it formats it as text and sends it to the browser instead of seeing it as binary and offering me a download box. PHP Code:

    include 'includes/configdb.php'
    include 'includes/opendb.php'

    $id      = $_GET['id'];
    $query   = "SELECT name, type, size, content FROM upload WHERE id = '$id'";
    $result  = mysql_query($query) or die('Error, query failed');
    list($name, $type, $size, $content) = mysql_fetch_array($result);

    header("Content-Disposition: attachment; filename=$name");
    header("Content-length: $size"); ....

Email With Attachment - Annot Be Accessed. The File May Be Read-only, Or You May Be Trying To Access A Read-only Location.

It is a basic email with an attachment. The email and attachment are getting sent and received ok. When the recipient tries to open the attachment, the right application opens (eg. Excel) but then throws up an error. I am using base64 encoding. For example:

.xls file with base64 encoding:
'testing.xls' cannot be accessed. The file may be read-only, or you may be trying to access a read-only location. Or, the server the document is stored on may not be responding.

.pdf file with base64 encoding:
There was an error opening this document. The file is damaged and could not be repaired.
so the file isn't being decoded right. I have tested on Yahoo and Outlook. PHP Code:
