Description:
------------
According to the documentation, filesize() supports wrappers that also support stat().

This seems to be false with both PHP 5.1.6, and 5.2.1-dev.

Unfortunately this function does not work as expected with FTP URLs. See the reproducable code for an example.

However, the manual states that "As of PHP 5.0.0 this function can also be used with some URL wrappers. Refer to Appendix M, List of Supported Protocols/Wrappers for a listing of which wrappers support stat() family of functionality."

From the manual, in regards to "Appendix M, List of Supported Protocols/Wrappers" in the "FTP and FTPS" section: "Supports stat() No As of PHP 5.0.0: filesize(), filetype(), file_exists(), is_file(), and is_dir() elements only. As of PHP 5.1.0: filemtime()."

Reproduce code:
---------------
<?php
print filesize("http://au2.php.net/distributions/php-5.2.0.tar.bz2")."\n";
?>

Expected result:
----------------
6789838

Actual result:
--------------
Warning: filesize(): stat failed for http://au2.php.net/distributions/php-5.2.0.tar.bz2

Changed summary from "HTTP/FTP and filesize()" to just "FTP and filesize()".

Originally I thought this was HTTP *and* FTP related, however it seems the manual only mentions FTP supporting stat() so for all intensive purposes, change the URL in my example code to:

ftp://ftp2.au.netbsd.org/pub/php/php-5.1.1.tar.bz2

or something else on an FTP server. My apologies.

Works for me:

PHP 5.2.1-dev CLI

Ubuntu 6.10

php -r "echo filesize('ftp://ftp2.au.netbsd.org/pub/php/php-5.1.1.tar.bz2');"

I've resolved this issue by writing my own (I think, better) fix in PHP, its here: http://au3.php.net/manual/en/function.filesize.php#71098

But this does still not resolve the underlying issue on why its not working for me.

Don't use --with-curlwrappers
