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().
