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.

There was an error opening this document. The file is damaged and could not be repaired.

Converting Binary To String Then Back To Binary

This is the synopsis: the PHP code is an interpreter of commands given in a terminal-like fashion, so as a string. Basically PHP receives a string argument, interprets it based on a given regular expression and then execute it. Here, the code receives a string similar to

ftp>fput -file(contents-of-file)

In this case, the code will ftp-fput a string to a given server. Works fine when file is ASCII. Now if the file is binary (ie, an image), the regex will bug and even if it wouldnt I want to encode the binary contents of the file so it can fit into the command string. I then need to be able to decode it on the interpreter side. I've tried base64 encode/decode, hex2bin bin2hex, pack unpack, but the file ftp'd always ends up not being readable by browser. The generated file, when attempted to be opened on Linux, generates an error like

Fatal error reading PNG image file: PNG file corrupted by ASCII-conversion

Binary File

I have a file with information formatted in Binary, which was saved from a C++ program. It's in a structure with different data types: Strings, integers, more structures. I use fread() to read each structure, and it returns the binary data, but I can't seem to get it to understand what part of it I want to use.

Create A Function That Will Use The File Read Function But Not Read The Codes Inside That File

What I want to do: What I want to do is create a function that will use the file read function but not read the php codes inside that file. e.g. <?php print "hello"; ?> would just send out the word hello, php codes that get information from a database would do the same, it would print out the information being written by the php code. Example of the database php codes:

$res = mysql_query($sql);
while($row = mysql_fetch_array($res)){
print $row["table_data"];

Lets say $row["table_data"] equals the name "Bob", that php code will send out the name Bob plus other names that could be printed from that php code and leave the php coding out so it does not get printed after  being put through the ReadFile function.


All the function above does is reads the file and that means the text between the <? & ?> tags also get read, what I want to know is how I could make a function that calls the page as it is ment to be shown. E.G. - If I wanted to get the current year and on the "" page I write <?=date('Y');?> what fopen does is read that as it is but what I need it to do is to run the code as it would normaly do and for example it would print out "2010" and thats what fopen would read. So <?=date('Y');?> on the file will print out 2010 after going through the ReadFile function.

Puzzling Dilemma With Fopen() - Generate A RSS File From A File Via Reading The Latter Into A Buffer

I'm changing a site. Currently I'm changing the PHP script that generates a RSS file from a PHP file via reading the latter into a buffer then disecting its data to then write to a new XML file. Before I was opening a source PHP file online. Now, I've changed the path to open the source PHP file be it localhost or online.

$rss_from_file= $_SERVER['DOCUMENT_ROOT'].'/online-auto-news/ford/ford-auto-news.php';
//open source and destination files
$rss_source_file = fopen("$rss_from_file", "r") or die("can't open file [SOURCE]");
$rss_write_file = fopen("$rss_to_file", "a") or die("can't open file [DESTINATION]");
//read the entire contents of source file into buffer
while (!feof ($rss_source_file))

The bad news: ford-auto-news.php is a long file, i.e, a couple hundred lines of code. When I however test for $source_file_array_count it will always report "1" suggesting that only one line from the source PHP has been read into $source_file_contents. This is indeed the case because if I echo out $source_file_contents I will always get "</html>" hence the absolute last line of code in the source PHP file.

The problem: Basically, why is it opening the file ok, even reading the data within the file but only reading the last line thus causing the $source_file_contents to be "1". This naturally makes the rest of the script fall over given it looks for tags nested within the source PHP file.

$rss_from_file always reports a valid path to the source PHP file, which is as I've said above, proven by the fact that $rss_source_file reports "Resource Id #4" on fopen(). This script worked absolutely fine when $rss_from_file was provided in the form of "http:\www......etc". Logically one could say it's opening the file ok, reading the file ok but somehow only skipping to the last line in the file, i.e. while (!feof ($rss_source_file)) always loops only once.

i wrote this to create a sitemap for my users on my community site, The have their own personal area a mini site so to speak. currently this is working by adding to a simple text file, i then manually add the new entries into the XML sitemap file.

The closing tag which i need to delee before appending the new data.


This is my current code

$url = "<url>";
$loc = "<loc>";
$location = "$domlink/users/index.php?$uid";[code]......

I just need to know how to delete the last line in a file, after that i know what to do
