with apache+php there couple different ways: server configuration or php code. benefits of performing kind of check in server configuration applied everywhere, or on per-directory basis without having change php on every page in folder or on site. server configuration provides faster runtime.

server configuration

using mod_rewrite, add following lines vhost config file:

rewriteengine on rewritecond %{https} off rewritecond %{server_name} (.*) rewriterule (.*) https://%1/$1 [r=301,l]

obviously, mod_rewrite must enabled on server work. apache's mod_rewrite documentation has more details.

php code

as others have mentioned, php provides header function can used set location http response header, , redirect client https. not require access server configuration or mod_rewrite.
