Solution in PHP (judge verdict: Accepted)

<?php
    $num = explode(" ",trim(fgets(STDIN)));
    
    hikaku($num,0,1);
    hikaku($num,1,2);
    hikaku($num,0,1);
    
    echo implode(" ",$num)."\n";
  
  function hikaku(&$num, $i, $j){
        if($num[$i] > $num[$j]){
            $temp = $num[$i];
            $num[$i] = $num[$j];
            $num[$j] = $temp;
        }
  }
