Answer 1

Assuming you have a working PHP implementation, try:

location / {
    rewrite ^/c-(.*)$ /catpost.php?id=$1 last;
    rewrite ^/a-(.*)-(.*)$ /archives.php?month=$1&year=$2 last;

    try_files $uri $uri/ @rewrite;
}
location @rewrite {
    rewrite ^/(.*)$ /viewpost.php?id=$1 last;
}

The main thing to remember is that nginx URIs begin with a leading /.

The first two rewrites may be inside the location block or not - depending on what other location blocks you have. See this document for details.

The conditional rewrite is basically what try_files is designed to do. We use a named location to lose the leading /. See this document for details.
