php perform isset in if statement without grouped statement

I have this if statement

if ($something !== $array[$key]) {
    // do something
}

But I can't be 100% sure that $array[$key] exists. So I'd like to do something like this:

if ($something !== $array[$key] ?? null) {
    // do something
}

The if statement should run when the array key does not exist or or different from the variable. Of course, I could do something like this:

if ($something !== (isset($array[$key]) ? $array[$key] : null)) {
    // do something
}

But I want to avoid this since it makes the code less readable. Are there any other options except this one:

$compare = $array[$key] ?? null;
if ($something !== $compare) {
    // do something
}
Solution

  • Following code might help:

    if (!array_key_exists($key, $array) || $array[$key] !== $something) {
   // Do it
}
