This is your fucked up comprehension of comparison.

You are making an incorrect assumption about the way a string variable is
compared to the number 0. You are not comparing the string "Zero" with
the strings "A" and "Z", you are comparing the number 0 with the strings
"A" and "Z". If you check the relevant php documentation, you will
understand that the behaviour here is exactly as it is documented to be.

You are not comparing the string "zero", you are comparing the number 0.
You are only considering part of the test you are discussing in your
above statements. You need to consider the whole test. The behaviour
appears on inspection to be correct.
