if you use ob_start with a callback function as a parameter, and that function changes ob string (as in example in manual) don't expect that ob_get_contents will return changed ob.

it will work as you would use ob_start with no parameter at all. So don't be confused.

transfer image, another method (alternative to fsockopen or function socket) :



server(192.168.0.1)

makeimage.php

       ...........

       ...........

       $nameimage="xxxx.jpg"

       $comand=exec("plotvelocity.sh $nameimage $paramater1 $paramater2");

       ob_start();

        readfile($nameimage);

        $image_data = ob_get_contents();

        ob_end_clean();

        echo $image_data;

        unlink($nameimage);



Client  (192.168.0.2)

  $bild="images/newimage2.gif";

  $host="192.168.0.1";

  $url=file_get_contents("http://$host/makeimage.php?$querystring");

  $fp = fopen("$bild", 'wb');

  fwrite($fp, $url);

  fclose($fp);

  echo '<img src="'.$bild.'">';
