Message:

I have a code similar to this:

if($a) {

  return $a;

} elseif($b) {

  return $b;

} elseif($c) {

  return $c;

} else {

  return $d;

} 

it is honestly not so looking good but I need to check the variables to respect some sort of priority order. I was guessing if there is a better way to write this?

My Answer:
You can refactor the code using a switch statement instead of multiple if-else statements. Here's how you can do it:

php
switch (true) {
case $a:
return $a;
case $b:
return $b;
case $c:
return $c;
default:
return $d;
}


This way, you can still check the variables in the desired priority order while making the code more readable and maintainable.
