Is === in PHP binary-safe in string comparison?

Question

Php functions strcmp, strcasecmp and other from this family are binary-safe.

Are operators == and === binary-safe?

And if yes what should be used in binary-safe string comparison: functions or operator?

(binary-safe: "operator or function that can be applied to variables without altering their current state")

They are, by your definition, but if you're comparing strings containing binary data, you should be aware of the fact that in PHP $a == $b can return true even when $a and $b are different. Example: "2e2" == "200"
