ob_get_status() returns status information on either the top level output buffer or all active output buffer levels if full_status is set to TRUE.
If called without the full_status parameter or with full_status = FALSE a simple array with the following elements is returned:

Key: level

Key: name
Value: Name of active output handler or ' default output handler' if none is set
Key: del
Value: Erase-flag as set by ob_start()
If called with full_status = TRUE an array with one element for each active output buffer level is returned. The output level is used as key of the top level array and each array element itself is another array holding status information on one active output level.
The full output contains these additional elements:
