# sudo pecl install apc

Starting to download APC-3.1.6.tgz (-1 bytes)
....done: 3,585 bytes
Could not get contents of package "/tmp/tmpspT8Og/APC-3.1.6.tgz". Invalid tgz file.
Download of "pecl/apc" succeeded, but it is not a valid package archive
Error: cannot download "pecl/APC"

What does this error mean? How do I fix it, thank you.

would not be surprised to find that 3k file is an html page. perhaps a 404 or a 503? Also, did you install the pre-requisites? The default CentOS 5.5 requires up-to-date php-pear, php-devel, and httpd-devel before pecl can run and compile apc.
