I already read the documentation, but when testing, I'm still not able to understand well the difference between them.
For example, with this simple file:

QUESTION
I'm confused about the speed of the sizeof($x) vs $x when in a loop. This site: phpbench.com claims that the loop of sizeof($x) without pre calc -count() is THOUSANDS of percent slower than with pre calc count(). So I did a test as below, but I'm not sure if this is the right way to test it. The results show that the time is almost the same for each function. So I don't understand how it would be so much different from the phpbench website.
In summary, I'd like to know a definite answer if function a (with sizeof($unset)) is really considerably slower than function b (with pre calculated $unset value). I think now the values/functions are stored in memory so sizeof($x) could actually be faster than on servers from several years ago?

and count()
perform about the same, however to squeeze more performance out of the loop itself you can do the following:

Install PHPbench
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
