PHP command line output buffer outputs regardless of buffer settings

Question

I have some classes I am writing unit tests for which have echoes in them. I want to suppress this output and thought ob_start() and ob_clean() would s

The following solves this problem for me. Without calling ob_end_clean(), the contents of the buffer remain until the script's end, where it is flushed.

ob_implicit_flush(false);
ob_start();    
/*
  ...
  ... do something that pushes countent to the output buffer
  ...
*/    
$rendered = ob_get_contents();
ob_end_clean(); // Needed to clear the buffer
