PHP namespaces grouped

Consider the following code:

<?php
namespace abc;
use function is_string;
use function get_class;

class main {
    protected $string;
    public function __construct( $string ) {
        if ( is_string( $string )) {
            $this->string = $string;
        } else {
            $this->string = get_class( $this );
        }
    }
}

Nothing fancy. Just a class in a namespace using two functions from the global namespace (is_string & get_class).
Those two functions are imported from the global namespace as that will give a small performance boost.

But if you have 20-30 build in PHP functions that list will get very long….

Luckily you can merge them:

use function is_string, get_class;

For now I’m not sure I’ll always import build in PHP functions, the boost is small. And it’s annoying to keep track of.
