ob_flush — Flush (send) the return value of the active output handler

Descrizione

ob_flush(): bool

This function calls the output handler (with the PHP_OUTPUT_HANDLER_FLUSH flag), flushes (sends) its return value and discards the contents of the active output buffer.

This function does not turn off the active output buffer like ob_end_flush() or ob_get_flush() does.

ob_flush() will fail without an active output buffer started with the PHP_OUTPUT_HANDLER_FLUSHABLE flag.
