ob_flush
Maybe it can be useful
$__ob_stack=array();
function ob_break() {
global $__ob_stack;
while (ob_get_level()>0)
array_push($__ob_stack,ob_get_clean());
}
function ob_continue() {
global $__ob_stack;
while (count($__ob_stack)>0) {
ob_start();
echo array_pop($__ob_stack);
}
}
ob_start();
echo "1"; // now we write to "ob" buffer
ob_break();
echo "2"; // now we write to stdout
ob_continue();
echo "3"; // now we write again to "ob" buffer
$output=ob_get_clean();
echo $output;
// output is 213

If you're trying to capture the output from an included 3rd party script you don't seem to be capturing everything, the following might help:
function ob_end_clean_all()
{
$s = "";
do
{
$s = ob_get_contents() . $s;
} while(ob_end_clean());
return $s;
}
This function closes all nested output bufferings, therefore closing any buffers that the included script does not explicitly close. It's basically a ob_end_clean that sweeps together all the output buffers instead of just the innermost one.

Notice that the function beneath does not catch errors, so throw in an @ before those ob_* calls

Running PHP4 < 4.3.0, you can simply add the following to use the function anyway:
<?php
if (!function_exists("ob_get_clean")) {
function ob_get_clean() {
$ob_contents = ob_get_contents();
ob_end_clean();
return $ob_contents;
}
}
?>
