[SOLVED] Check if file pointer is valid

[btherl]

Is there any is_file_pointer_valid() in php?  Something which will tell me either "Yes, that's a file pointer" or "No, whatever that thing is it isn't a file pointer"

I found the following..

 

if (is_resource($fp) && get_resource_type($fp) === 'stream') {
  ...
}

 

But it doesn't distinguish between stream types.. to do that you need to use stream_get_meta_data() and look even deeper.  I guess that is the price of flexibility.

get_resource_type should help you out.

Thanks thorpe!  I just learnt a whole lot about how complex php's streams and wrappers and so on really are
