Personal changes to Homebrew's extra/httpd-vhosts.conf. See on my blog: http://diegoe.be/2014/03/26/setting-up-apache-php-mysql-on-osx-with-homebrew

httpd-vhosts.conf

<VirtualHost *:8080>
    <IfModule php7_module>
        AddType application/x-httpd-php .php
        AddType application/x-httpd-php-source .phps
        <IfModule dir_module>
            DirectoryIndex index.html index.php
        </IfModule>
    </IfModule>

    ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot "/Users/diego/Sites"
    ServerName localhost
    ServerAlias localhost
    ErrorLog "/Users/diego/Sites/logs/localhost-error_log"
    CustomLog "/Users/diego/Sites/logs/localhost-access_log" common

    <Directory /Users/diego/Sites>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted
    </Directory>

    # PHPMyAdmin
    Alias /phpmyadmin /usr/local/share/phpmyadmin
    <Directory /usr/local/share/phpmyadmin/>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

For Apache 2.4 the Allow directive is deprecated!
