i wonder if its possible to combine both operators (OR and AND) in one if statement like this.
if($apple==1 && $orange==2 || cake==0)
What i want to state is: if apple equals 1 AND orange equals 2, OR cake equals 0 then do this. In other words, i need apple and orange to equal the numbers stated above OR cake to equal 0.
Is this expression correct? If not, whats the simplest way to do it?
Thank you.
You should use inner parentheses for precedence ..
The reason is.. the first condition that was wrapped inside the parentheses will be evaluated as a block
As the other user mentioned, && has higher precedence over the || there is no need for the parentheses , but say if your if statement goes on like this..
if($apple==1 || $orange==2 && cake==0)
Then you need to go on with ..
if(($apple==1 || $orange==2) && cake==0)
Sidenote : Always its a good practice to use parantheses...
&& has a higher precedence.&& has higher precedence than ||&& has higher precedence than ||. So your answer is correct
The expression
$apple==1 && $orange==2 || $cake==0
is equivalent to
($apple==1 && $orange==2) || $cake==0
because && has a higher precedence. As such, it means "when apple is 1 and orange is 2, or cake is 0".
While parenthesis can be used - and can make code more readable - they are not required in this case. However, parenthesis would be required when writing
$apple==1 && ($orange==2 || $cake==0)
which means "when apple is 1 and it is the case that either orange is 2 or cake is 0".
In your case the clause should look like following.
if(($apple==1 && $orange==2) || cake==0)
