czy jest mozliwosc "przeplatania" funkcji kontroli wyjscia miedzy soba? chodzi mi o cos takiego:

[PHP] pobierz, plaintext 
<?php
ob_start();
  echo 'jakis tekst'
  ob_start();
     echo 'lol2';
     $z2 = ob_get_contents();
  ob_end_clean();
  $z1 = ob_get_contents();
ob_end_clean();
?>
[PHP] pobierz, plaintext 

oczywiscie moj przyklad jest bledy, ale chce abyscie zrozumieli +/- o co mi chodzi.

Output buffers are stackable, that is, you may call ob_start() while another ob_start() is active. Just make sure that you call ob_end_flush() the appropriate number of times. If multiple output callback functions are active, output is being filtered sequentially through each of them in nesting order.

The following example shows an easy way to get rid of all output buffers:

Example 1. ob_end_clean() example

[PHP] pobierz, plaintext 
<?php
while (@ob_end_clean());
?>
