Re: socket_read() trouble with PHP_BINARY_READ

In the end I decided I'll just use the fsockopen(), feof(), fwrite, fread, etc. function-set instead (got the idea from PEAR's NET_Socket). And that seems to work just fine... too bad I couldn't get the low-level functions to work (still don't know why), but this works great...

thank you all for the help/support though!

Hi there!

Can't it be anything with filepermissions? Just a clue...

hello,

thank you for the help, but I've tried your code, and it returns the exact same thing :( the error #11 temporarily unavailable. If I remove non-blocking, or change the error to ignore to 11 (10035 in your code example) it simply "hangs" doing nothing *at all*...

I'm stumped; really.. thank you for trying though :)

Because of this line the function returns straight away.

MS> socket_set_nonblock($this->socket);

You have to catch the 'not ready' error something like this:
(The error code was under windows)

function get(){
  $ret = '';
  while(1){
    $sbuf = @socket_read($this->connection, 1024, PHP_BINARY_READ);
    if(false === $sbuf){
      $error = socket_last_error($this->connection);
      if($error != 10035){
echo "msgsock read() failed: reason: " .$error.' '. socket_strerror (socket_last_error($this->connection)) . "\n";
        return;//socket not happy
      }
    }else{
      $buf_read = strlen($sbuf);
      if($buf_read === 0) break; // end of text
      $ret .= $sbuf;
    }
  }
  return $ret;
}
