This function discards the contents of the topmost output buffer and turns off this output buffering. If you want to further process the buffer's contents you have to call ob_get_contents() before ob_end_clean() as the buffer contents are discarded when ob_end_clean() is called.
The output buffer must be started by ob_start() with PHP_OUTPUT_HANDLER_CLEANABLE and PHP_OUTPUT_HANDLER_REMOVABLE flags. Otherwise ob_end_clean() will not work.
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).
If the function fails it generates an E_NOTICE
.
The following example shows an easy way to get rid of all output buffers:
<?php ob_start(); echo 'Text that won\'t get displayed.'; ob_end_clean(); ?>
