ob_end_flush

(PHP 4, PHP 5)

This function will send the contents of the topmost output buffer (if
any) and turn this output buffer off. If you want to further
process the buffer’s contents you have to call
ob_get_contents() before
ob_end_flush() as the buffer contents are
discarded after ob_end_flush() is called.
The function returns TRUE when it successfully
discarded one buffer and FALSE otherwise. Reasons for failure are first
that you called the function without an active buffer or that for some
reason a buffer could not be deleted (possible for special buffer).

Note:
This function is similar to ob_get_flush(), except
that ob_get_flush() returns the buffer as a string.

The following example shows an easy way to flush and end all output
buffers:

Example 1. ob_end_flush() example

  while (@ob_end_flush());

Note:
If the function fails it generates an E_NOTICE.

The boolean return value was added in PHP 4.2.0.
