title: migrate php site from http to https
body: <p>i read the other threads about this topic but i couldn't find anything that i felt could apply in my case. It seams pretty basic though. I have a website built in php with apache server. In this moment all the traffic is done via http. The people who paid for the site, now want to move it to https. They bought a certificate and the web server hosts will install it. What changes do i need to make to make it work via https, besides changing the redirects within the code?
  I also found this link which seems pretty helpful, but i think maybe it's too complex?</p>
  
  <p>Thank you,
  Alex</p>
