You can edit that file with nano by running sudo nano /boot/config.txt and then scroll to the bottom and type
dtoverlay=w1-gpio
press ctrl+x and y to confirm, then sudo nano /etc/modules add the following 2 lines to the bottom:
w1-gpio
w1-therm
press ctrl+x and y to confirm , then reboot your pi. Add temp.php to /var/www/ then visit http://127.0.0.1/temp.php
