Using AND/OR in if else PHP statement

Question

How do you use \'AND/OR\' in an if else PHP statement? Would it be:

1) AND

if ($status = \'clear\' AND $pRent == 0) {
    mysql_query(\"UPDATE rent 
         


        

Answer 1

A bit late but don't matter...
the question is "How do you use...?" short answer is you are doing it correct

---

The other question would be "When do you use it?"
I use && instead of AND and || instead of OR.

$a = 1
$b = 3

Now,

if ($a == 1 && $b == 1) { TRUE } else { FALSE }

in this case the result is "FALSE" because B is not 1, now what if

if ($a == 1 || $b == 1) { TRUE } else { FALSE }

This will return "TRUE" even if B still not the value we asking for, there is another way to return TRUE without the use of OR / || and that would be XOR

if ($a == 1 xor $b == 1) { TRUE } else { FALSE }

in this case we need only one of our variables to be true BUT NOT BOTH if both are TRUE the result would be FALSE.

I hope this helps...

Answer 2

You have 2 issues here.

1. use == for comparison. You've used = which is for assignment.

2. use && for "and" and || for "or". and and or will work but they are unconventional.

Answer 3

AND is && and OR is || like in C.

Answer 4

Yes. The answer is yes.

Two things though:

• Many programmers prefer && and || instead of and and or, but they work the same (safe for precedence).
• $status = 'clear' should probably be $status == 'clear'. = is assignment, == is comparison.
