Thanks for this question. At first thought I wanted to ask why the hell is this important?!
But then I tested out the performance differences between == and ===. And (at least with my testing
environment (average time spend for 100.000 comparisons x 1000 tries to have an average result in php8.2) I
was able to find out that == needs only 75% execution time of ===. And I learned about a function
I didn't know before. microtime(true);

So thanks again for your great input!
