ob_end_clean — Clean (erase) the output buffer and turn off output buffering
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.
This function has no parameters.
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:
Example #1 ob_end_clean() example
<?php
ob_start();
echo 'Text that won\'t get displayed.';
ob_end_clean();
?>
