Question

Is there an method like isset so I can determine if there is a buffer to delete/flush?

Notice: ob_end_flush(): failed to delete and flush buffer. No buffer
to delete or flush.

I’m not turning error reporting down from the highest sensitivity as doing so is highly insecure if you do enough thinking. So how can I iron out this issue please?

Answer 1

Look at ob_get_level and/or ob_get_status.
