Most likely not soon... internally PHP uses a signed integer for string lengths and other things. What exactly do you want to do with this?

I have to manage astronomical images which are rather big !
I would like to get filesize to display basic data on them via
a browser.

If they are smaller than 4GB you can do this:

printf("%u", filesize("filename")); Everything larger would be a problem, as the return value from filesize is an integer.

thanks :)
But most of my files are bigger....will wait for
the next release ;) Thanks

You might try using standard shell commands
(ls -la) and capturing the values into either 
strings or double floats.  You could probably
work something out that would give you most of
what you need.

A hack... most definately, but I've had
good luck dealing with 64bit ints as doubles
without loosing too much precision.

Thanks your help :)
Will check the Changelog file in the next release.

Don't expect this to be added in the near future... it will probably wait until we all use 64bit CPUs ;)

Do you mean you are still using those old 32bits machine ? ;)

Yup :) Feel free to sponsor me with a 64bit machine :)

Need to get one first to install the next php release ! ;)

Problem tracked in #27792.
