   Why? Just:

chmod -R a+r,go-w $HOME/public_html/*

   If you really want to, you can create an array of directories by:

dirs=( $HOME/public_html/*/ )

    Why do all that?

## set $HOME/public_html to drwx--x--x
chmod 711 $HOME/public_html

## Add read permissions to all files under $HOME/public_html
chmod -R a+r $HOME/public_html

## Set execute permissions on all directories under $HOME/public_html
find $HOME/public_html -type d -exec chmod a+x,go-rw {} \;
