PHP Generators – an example

I’ve ignored generators for sometime in PHP, but recently realised why they can be quite handy 🙂 As an example, imagine you are querying a web service, which returns  data in chunks of up to 100 results….

Mockery (test doubles/mocking dependencies)

[This is a relatively old post I think I forgot to publish….] Previously, I’d only used PHPUnit’s mock implementation; however lately I’ve been exposed to Mockery. While they both achieve broadly the same result (at least from my point of view), here’s an example of how to mock dependencies with Mockery.

Fixing REMOTE_ADDR when behind a proxy/varnish server

I had an annoyance where varnish proxy infront of a LAMP server and the LAMP server therefore thought all clients were from the varnish proxy – rather than the client’s real IP address – i.e. $_SERVER[‘REMOTE_ADDR’] was set to the IP address of the Varnish proxy and not that of the client’s actual IP address.… Continue reading Fixing REMOTE_ADDR when behind a proxy/varnish server
