OR逻辑运算符的多条件php不返​​回false

Question

I have a conditional statement in php, when I add an OR logical operator it doesn't work as intended, in the below example it returns the code that I am trying to prevent it doing.

Individually each statement works just not when they are together as I have them below. It seems inefficient to repeat the code for each condition.

if (!is_sp_post_type('profile') || !is_category(array('previews','reviews')) || !is_single(array('previews','reviews'))) { //do stuff };

I have read this answer Is there a short-circuit OR in PHP that returns the left-most value? but I'm still stuck

Answer 1

Just make use of the AND (&&) operator.

The OR operator just needs one true to execute the conditional, whereas the AND operator needs all statement to be true.

I'm not hundred percent sure what you are trying to achieve, but I would also suggest having a re-look at your NOT (!) operator and how it is used in your code
