  • ob_get_clean — Get the contents of the active output buffer and turn it off
  • ob_get_contents — Return the contents of the output buffer
  • ob_get_flush — Flush (send) the return value of the active output handler, return the contents of the active output buffer and turn it off
  • ob_get_length — Return the length of the output buffer
  • ob_get_level — Return the nesting level of the output buffering mechanism
  • ob_get_status — Get status of output buffers
  • ob_implicit_flush — Turn implicit flush on/off
