In an awesome article at Sitepoint Christopher Pitt explains how he used the yay macro library to build up plugin framework to add new language features tophp.

Chris made plugins that allows this syntax in PHP.

// short closure syntax $items = ["one", "two", "three"]; $ignore = "two"; array_filter($items, ($item) => { return $item !== $ignore; }); //class accessors class Sprocket { private $type { get { return $this->type; } set { $this->type = $value; } unset { $this->type = "type has been unset"; } } }

As with all things, this can be abused. Macros are no exception. This code is definitely not production-ready, though it is conceptually cool.

Please don’t be that person who comments about how bad you think the use of this code would be. I’m not actually recommending you use this code, in this form.

Having said that, perhaps you think it’s a cool idea. Can you think of other language features you’d like PHP to get? Maybe you can use the class accessors repository as an example to get you started. Maybe you want to use the plugin repository to automate things, to the point where you can see if your idea has any teeth.

Very cool stuff.
