It’s about time that PHP joined the band wagon of anonymous functions. Anonymous functions, also known as closures, are functions with no specified name. These functions are stored in variables and can be passed around. Anonymous functions have been in other programming languages like Javascript, so if you know Javascript then anonymous functions are nothing new.

Colon syntax is another way to style your PHP code. Instead of using curly braces you use colons. Below I have included an example of a couple different curly brace styles and also each statement using the colon syntax. I don’t know of any performance benefits or loss to using this syntax over any other. Please comment here if you have any more information about its affects on performance.
