PHP: Help with if OR issue

Had this twice now, don't know what the problem is, I have this normal if statement, with an OR attribute

if((checkBlock($showU['id'], $USER, 'Wall') != 1) || (checkBlock($showU['id'], $USER, 'Wall', 1) == 1)) { 

I want it to check whether the first checkBlock is != 1, OR if checkBlock is == 1

First if checkBlock should be true, if I have blocked an user and the user tries to visit me.

Second should开发者_JAVA百科 be true if I have blocked an user and I try to visit him.

The first ifstatement works with the code above, but not the if statement (the if i have blocked and visits him)..

But the second works if I remove the first statement.. but I want to check for both.

How can i make them both check work? I have tried OR, but didnt affect the issue.

PHP is skipping the second check when the first is true because of short-circuit boolean evaluation. That is, if you have (A || B) and A is true, then there's no need to check B because your conditional has already passed. If you want to check for both conditions then you need to use AND not OR.

---

Your starting condition doesn't make sense, whether you use AND or OR, your checking the same value (consider the interpreted value of your function like: 1 != 1 OR 1 == 1, that doesn't make sense). Please consider checking the values and your logic.

If you want to check them both, it should be AND (&&), not OR
