in my code I wanted to compare two strings and first I did it with === but later i tryed strcmp(). When i write:
echo strcmp("test","test");
the result was 0. I also tried it with ===
echo ($subject === $empty)
there i used my actual strings i wanted to compare.
However. Why is the string comparde method only True if the zweo string arent the same. Because:
echo strcmp("test","tedddst");
delivers True.
strcmp doesn't return a boolean true/false, it returns an int. From the strcmp documentation:
Returns < 0 if str1 is less than str2; > 0 if str1 is greater than str2, and 0 if they are equal.
