Why using the "use function" import statements for PHP native functions? - Muzikant - 01-13-2024
Hi. I am strugling to understand, why to use "use function" import statement for PHP native functions. An example code:
PHP Code:
<?php
namespace Acme\Package;
use Acme\Package\SomePackage;
// why this?
use function md5;
use function json_encode;
class AnotherPackage {
// some code with using of a md5 and json_encode functions
}
Can you write me, why to import the PHP native functions? I have no idea and could not find an answer.

1. All PHP native functions are defined in global namespace. That is like \md5(), \json_encode().
2. We can define the same name function in another namespace like \Acme\Package\md5().
If you write `use function md5;`, you will surely call \md5(), when you write code `md5('foo')`.
If you don't write `use function md5;`, \Acme\Package\md5() will be called if defined.

I understand it now, thank you. In the case I found it, it is an another security level to avoid discrepancies while working with third party code I guess.
