ob_implicit_flush

Description

ob_implicit_flush will turn implicit flushing on or off. Implicit flushing will result in a flush operation after every block of code resulting in output, so that explicit calls to flush will no longer be needed.

Note: Printing empty strings or sending headers is not considered output and will not result in a flush operation.

Note: This function does not have any effect on user level output handlers such as those started by ob_start or output_add_rewrite_var.
