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
ob_get_clean
(PHP 4 >= 4.3.0, PHP 5)
ob_get_clean — 現在のバッファの内容を取得し、出力バッファを削除する
説明
string ob_get_clean
( void
)
現在のバッファの中身を取得し、出力バッファを削除します。
ob_get_clean() は、基本的に ob_get_contents() および ob_end_clean() を同時に実行するのと同じです。
返り値
出力バッファの内容を返した後で出力のバッファリングを終了します。 出力バッファリングが開始されていない場合は FALSE が返されます。
例
例1 単純な ob_get_clean() の例
<?php
ob_start();
echo "Hello World";
$out = ob_get_clean();
$out = strtolower($out);
var_dump($out);
?>
上の例の出力は以下となります。
string(11) "hello world"

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;
}
}
?>
