Web Hosting Talk : Web Hosting Main Forums : Programming Discussion : byte string in php

[Adam Hallett]

I'm creating a php script that uses Gnutella. I've parsed past the headers and now I need to process the descriptor id. The descriptor id is a 16-byte string uniquely identifying the descriptor on the network." How do I convert a byte string into a regular string?

I believe you're looking for this function

PHP has all sorts of multibyte string functions built right in.

Do I need to use ord() with that function?

Btw, http://rfc-gnutella.sourceforge.net/...0_6-draft.html

Here's the code:

while ( ! feof($fp ) ) {
$buf .= fread($fp,1);
if ( strstr($buf, "\r\n\r\n") ) {
$split = split ("\r\n\r\n",$buf);
$data = $split[1];

var_dump($split);

while ( strlen($data) < 23) {
$data .= fread($fp,1);
}

break;
}
}
while(1){
$descrip = substr($data,0,15);
$ttl = ord($data[17]);
$hops = ord($data[18]);
$payload_len = substr($data,19, 22-19);

$plen = ord($payload_len);

$this->_log("hops: $hops; ttl: $ttl payload_len: $plen,$payload_len");

switch (ord($data[16])) {

case 0x00:
$this->_log('ping');
break;
case 0x01:
$this->_log('pong');
// $sin = fread($fp, $datasize);
break;
case 0x40:
$this->_log('push');
// $sin = fread($fp, $datasize);
break;
case 0x80:
$this->_log('query');
// $sin = fread($fp, $datasize);
break;
case 0x81;
$this->_log('queryhit');
// QueryResponseDataAvail($fp, $datasize);
break;
} // switch


fread($fp,$payload_len);
$data = '';
while ( strlen($data) < 23 ){
$data .= fread($fp,1);
}

}
