How to write if else in short

Question

Someone show me how I can write this line of codes in short.

if($x[$key_url] == $last_news)          
{
    $new_next = $first; 
}
else{
    $new_next = $x[$key_url + 2];   
}

Answer 1

Using ternary operator it becomes:

$new_next = $x[$key_url] == $last_news ? $first : $x[$key_url + 2]

Answer 2

Here is the example

$new_next = $x[$key_url + 2];   
if($x[$key_url] == $last_news) {
   $new_next = $first; 
}

Or

 $new_next =  ($x[$key_url] == $last_news) ? $first : $x[$key_url + 2];
