Main page on main domain, affects subdomain. - php

Question

So I have www.example.com and m.example.com. Now when I go to m.example.com I see the same content as www.example.com. I have an index.php inside the m.example.com, so I'd expect that to show instead.
Here's my m.website.com.conf
<VirtualHost *:80>
ServerName m.example.com
ServerAdmin webmaster#localhost
DocumentRoot /var/www/m/
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
And a part of my apache2.conf
<VirtualHost *:80>
ServerAdmin web#webite.com
DocumentRoot /var/www/m
ServerName m.example.com
ErrorLog /var/log/apache2/mlog.log
</VirtualHost>
So now I'd expect it to work off of /var/www/m, and inside that I have a separate file that isn't rendering, because the main domain takes it over. Any help would be great.

For adding virtual hosts to your Apache use this tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-virtual-hosts-on-debian-7
It's my first time seeing someone that puts virtualhost information on 2 files, both at the apache2.conf and at the sites-available folder. In my setup, I have an "include" statement in my apache2.conf file which includes the files in the sites-enabled directory and not other information at all - this is the default for Debian Linux, I didn't touched it at all. I put all my virtualhost configurations in the sites-available directory. That's where you should put them also.
