# ob_end_flush

(PHP 4, PHP 5)

ob_end_flush — Flush (send) the output buffer and turn off output buffering

### Description

bool ob_end_flush ( void )

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.

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

### Return Values

Returns `TRUE` on success or `FALSE` on failure. 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).

### Errors/Exceptions

If the function fails it generates an `E_NOTICE`.

### ChangeLog

Version | Description
--- | ---
4.2.0 | The boolean return value was added.
