I had a problem with checking falsy conditions and don't understand how 'false' works.

I tested the code above,

echo (0 == false); //->true
echo ("0" == false); //->true
echo ("0" == 0); //->true
echo ("000000000000" == 0); //->true
echo ("000000000000" == false); //->false

And don't understand why the last result is false instead of true.

Thanks for your explanation.

"000000000000" and "00" and indeed anything other than "0" are evaluated as true because they are treated as regular non-empty strings in PHP and therefore not considered as a falsy value. PHP will only evaluate "0" as false.
