Hi,
I'm having trouble with output buffering limitation
and the output_callback function of ob_start.
look at this script :
<?php
function ob_perso_handler($buffer)
{
ob_start();
echo 'foo';
$buffer .= ob_get_contents();
ob_end_clean();
return $buffer;
}
ob_start('ob_perso_handler');
echo 'Hello World !';
?>
it outputs : "Fatal error: ob_start(): Cannot use
output buffering in output buffering display handlers"
Why then ? It would be a killer feature for my next
killer appz !
I've tried also :
<?php
function ob_perso_handler1($buffer)
{
return $buffer . 'f1';
}
function ob_perso_handler2($buffer)
{
?>
foo
<?
return $buffer . 'f2';
}
ob_start('ob_perso_handler1');
ob_start('ob_perso_handler2');
echo 'Hello World !';
?>
but were does "foo" go ?
any idea on that ? maybe some source change to PHP to
permit one or the other solution ?
I'm new to this mailing list, please redirect me to
the correct one if I'm wrong here. My thought was it
was a developper problem, since change to the source
has to be done to enable such this feature ...
Many thank's for any help !

I don't really understand your problem, it seams to me you want to add
output to the buffer in the output handler!?
Why not just:
<?php
function myObHandler($buffer)
{
$buffer .= 'foo';
return $buffer;
}
ob_start('myObHandler');
?>
