Assistance using php_start_ob_buffer

Okay after looking at the php source looks like the problem is in
php_request_shutdown where it flushes all the buffers.

So I'm trying from my extension to register a shutdown function to be
called prior to that(only alternative I see other than mucking the php
source).

I've figured out basic calling for the

zif_register_shutdown_function

but I'm stuck on how to put something on the

argument_stack

so that it can pass

zend_get_parameters_array

which is called in z

if_register_shutdown_function.

any help appreciated

thanks

Hi,

I'm trying to write an extension that(running under php in fcgi mode)
does the equivalent of

-php.ini
auto_prepend_file = start.inc
auto_append_file = end.inc

-start.inc
ob_start()

-end.inc
$len = ob_get_length()
// modify buffer slightly based on length value
// php prints final buffer on script termination

So I thought I merely needed to do the C equivalent of these, in short:

RINIT

php_start_ob_buffer(NULL, 0, 0 TSRMLS_CC);

RSHUTDOWN

zval * outbuf = NULL;
zval outbuflen;

INIT_ZVAL(outbuflen);

if ( php_ob_get_length(&outbuflen TSRMLS_CC) != FAILURE &&
Z_L_VAL(outbuflen) != 0 ) {

ALLOC_INIT_ZVAL(outbuf);
php_ob_get_buffer(outbuf TSRMLS_CC);

// Modify buffer based on len parameter

}

// Done php prints buffer by itself on script return

However no matter what variation on the above I've tried, including
different php_ob_* api calls I can't ever get any buffer length(I do see
script data output). It's like ob_start() was never called.

In php.ini I have
output_buffering = Off

Can someone please point out what I'm missing here? thanks!
