TIL*¹ you can import just a function in a .php file, like we do with classes. It works from PHP 5.6+, so there’s no weird compatibility issue. And it’s dead simple.
Here’s an example from Safe PHP, specifically let’s say we want to use the safer*² version of
json_decode. Pay attention at how this allows us to override PHP’s default
json_decode global function:
// First we import it use function Safe\json_decode; // And then we just use it $foobar = json_decode($content);
Yes, it’s not a jode. That’s all. You tell PHP that what you’re importing is a function and the just use the function’s name instead of a class name. After that, you can use said function in you code as if it were a global or local function. How cool is that?!

falsewhen an error is encountered. For more information about this project you can go to their repo https://github.com/thecodingmachine/safe
