I may have up to a few dozen curl handles (from curl_init()), which I'm 
passing off to curl_multi etc... to make in parallel.  As requests 
finish, I'm using curl_multi_info_read to figure out which curl handle 
completed.  I have other objects which have additional information about 
the curl handles which I need in order to process them.

I'm disappointed to see there isn't an equivalent to spl_object_hash for 
resources.

In any case, it looks like casting a resource to a string results in a 
unique identifier [1], but the manual also states that the structure is 
"subject to change".  I interpret that as it will still be unique (at 
least for that resource type), but it may be in a different format.

So, I'm wondering if using the (string) cast of a Resource as an array 
key is going to lead to unexpected bugs during some future PHP upgrade. 
  I'd rather not loop through all my objects to find the matching one. 
It's a small enough set that I might do that if there isn't another 
reliable way to achieve this, but I'd rather have an O(1) solution.


Thanks,
Daniel.
