Ok, thx...it seems, it was a missunderstanding while reading the manual
(http://reklov.homeip.net/manual/PHP/function.ob-get-flush.html):
ob_get_flush -- Flush the output buffer, return it as a string and
turn off output buffering
<--- i understood it this way: flush the output into a string an turn
off...
instead of flush (understood as delete) the output, send it and return
to a string and turn off...
perhaps this happened, because of my not very well english (i guess,
you have already noticed that...)
Thx for the answer

Thank you for taking the time to write to us, but this is not

http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
from manual (http://nl3.php.net/ob_flush):
ob_flush -- Flush (send) the output buffer

Description:
------------
On the contrary to the tip in the documentation
(http://www.php.net/manual/en/function.var-dump.php), there's no chance
to stop var_dump() from outputting. Although you can save it with
output buffering into a string, it will be sent to output, anyway...
As you can see in the example, the var_dump()-output is sent to output
twice, first from var_dump(9), second from echo $output.
Reproduce code:
---------------
<pre>
<?php
$a = 'Output';
echo 'Output from var_dump():'."\n";
ob_start();
var_dump($a);
$output = ob_get_flush();
echo 'Same as above: '."\n".$output;
?>
</pre>
Expected result:
----------------
<pre>
Output from var_dump():
Same as above:
string(6) "Output"
</pre>
Actual result:
--------------
<pre>
Output from var_dump():
string(6) "Output"
Same as above:
string(6) "Output"
</pre>
