i have the same problem with these same zip files.

i am using mozilla firefox version 1.0.6 on windows 2000 sp4
and tried to unzip these files with winrar 3.50. i have redownloaded these files but no luck in extracting them.

i have come to the conclusion that the files must be corrupt on the server or perhaps in a combination of the above configuration makes them corrupt.

i downloaded the older php version to see for any compatibilities within my code.

maybe someone should repackage them and put them on the server again.

i have also downloaded all other php version from 4.0.5 to latest and found no other corrupt zip files.

in addition to my previous report,

'php-4.0.2-Win32.zip' does not seem corrupt but packaged like tar.gz files do as an uncompressed archive within a compressed file.

if i unzip 'php-4.0.2-Win32.zip' i get the file 'php-4.0.2-Win32' with no extension, if opened with winrar it apears to be an archive wich i can extract. 

also the other zip files,
php-4.0.1-Win32.zip
php-4.0.1pl1-Win32.zip
php-4.0.3-Win32.zip
php-4.0.4-Win32.zip

give an "unexpected end of file" error making me believe 
they might not be fully uploaded to the server, i.e. an 
incomplete ftp transfer.

i hope this helps in restoring the php museum.

The files were compressed with gzip on top of zip. I have uncompress them now, and they seem to be fine.

Thanks for the report!
