Reading Binary Files in PHP

[ihere]

Recently I need to write a PHP script that would process a binary file I had created in my VB program. Can PHP do this? and how?
PS: Sorry for my bad English.

It is not so simple as you think. I have a binary file test.qbt that I had created in my VB6 program. In this binary file: simple text, picture and expression. Now i have to read all data from that file and write to browser (text, picture and expression). I dont know how? Please help me!!!!

[PHP]
<?php
session_start() ;
$fp=fopen("p1.p hp",'rb');
$i=0;
do{
fseek($fp,$i);
$buff=fread($fp ,1);

echo ord($buff))."<b r>\n";
$i++;
}while($i<=file size('p1.php')) ;
[/PHP]

that is the way to do it-(i hope :-)
it reads file byte by byte and displays as binary

by the way how u going to use those images?
i hope it helps

You will need to know the file format structure of the binary file you are using. Do you?

You have to send the right HTTP Headers that define the Content-Type.. eg:
[PHP]
header('Content-Type: image/png');[/PHP]

If you image is a png image.

Then read the binary image data from teh file and output it in the HTTP Body.

[PHP]
// send HTTP headers
header('Content-Type: image/png');
header('Content-Length: '.filesize($bin ary_file_path)) ;

// send HTTP Body
$fp = fopen($binary_f ile_path, 'rb'); // open file pointer
fpassthru($fp); // dump file stream to http
fclose($fp);

[/PHP]

I think this is a stupid question..but how do you dump it in the http body? I cant seem to make it appear in my webpage. All I get is a corrupted file. Thanks for your reply!
