  Some stuff
}

// Needed Output
echo check_status("User", 38, true); // "Hello User, Your Age Is 38, You Are Available For Hire"
echo check_status(38, "User", true); // "Hello User, Your Age Is 38, You Are Available For Hire"
echo check_status(true, 38, "Osama"); // "Hello User, Your Age Is 38, You Are Available For Hire"
echo check_status(false, "User", 38); // "Hello User, Your Age Is 38, You Are Not Available For Hire"

    You can do a check on the type of the variable and concatenate the string to get the final one. I would do something like:

    <?php
function check_status($a, $b, $c) {
  $name = null;
  $age = null;
  $availability = null;
  if (is_string($a)) $name = $a;
  if (is_string($b)) $name = $b;
  if (is_string($c)) $name = $c;
  
  if (is_int($a)) $age = $a;
  if (is_int($b)) $age = $b;
  if (is_int($c)) $age = $c;
  
  if (is_bool($a)) $availability = $a;
  if (is_bool($b)) $availability = $b;
  if (is_bool($c)) $availability = $c;

  $availableString = $availability ? "available" : "not available";
  echo "Hello $name, your age is $age, you are $availableString for hire n";
}

check_status("John", 26, true);
check_status(26, "John", true);
check_status(true, 26, "John");
check_status(true, "John", 26);
check_status(false, "John", 26);
?>

    The output is:

    Hello John, your age is 26, you are available for hire   
Hello John, your age is 26, you are available for hire 
Hello John, your age is 26, you are available for hire 
Hello John, your age is 26, you are available for hire 
Hello John, your age is 26, you are not available for hire

    It’s not the shortest way to do it, it’s an example. It’s all about concatenating variables after checking the type.
    The concatenation could’ve be done with sprintf instead

    For, these cases you can use associative array as a function args.

    function check_status($params) { 
      $availability = $params['availability'] ?? false;
      $name = $params['name'] ?? '';
      $age  = $params['age'] ?? 0;'enter code here'
      $availableString = $availability ? "available" : "not available";
      echo "Hello $name, your age is $age, you are $availableString for hire";
    }
