DPC2019: Interface Segregation for PHP - Dan Ackroyd
"Interface Segregation for PHP by Dan Ackroyd
When people give talks on the ""S.O.L.I.D."" design principles one of the letters that doesn't get enough attention is the ""i"" - the ""interface segregation principle"". This talk seeks to redress that imbalance by going into a bit more in-depth into:
An introduction to interface segregation and an explanation of how it makes your code easier to test.
Why in PHP we need to apply the principle more broadly, to make types be more specific, so that code is more reasonable. *Me babbling on about emotions, and how good code is boring. Which is good!
What will people learn from your talk:
The difference between code being reasonable and understandable.
The purpose behind using types to make your code be less likely to have bugs.
How 'interface segregation' applies to more than just classes in PHP.
How to overcome some emotional barriers to writing clean code.
