ob_get_contents

(PHP 4, PHP 5)

ob_get_contents — Gibt den Inhalt des Ausgabe-Puffers zurück

Beschreibung

string ob_get_contents ( void )

Gibt den Inhalt des Ausgabepuffers ohne Löschung zurück.

Rückgabewerte

ob_get_contents() gibt den Inhalt des Ausgabepuffers zurück ohne ihn zu löschen oder FALSE, wenn die Ausgabe-Pufferung nicht aktiv ist.

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

<?php

ob_start
();

echo 
"Hello ";

$out1 ob_get_contents();

echo 
"World";

$out2 ob_get_contents();

ob_end_clean();

var_dump($out1$out2);
?>

Dieses Beispiel produziert folgende Ausgabe:


string(6) "Hello "
string(11) "Hello World"

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.'">';

naturally you can transfer whichever thing and not only images
