Solution in PHP (judge verdict: Accepted)

<?php
$D=[];
$D[0]=trim(fgets(STDIN));

for($i=1;$i<10;$i++){
  $d=trim(fgets(STDIN));
  if($D[0]<$d){$D[$i]=$D[0];$D[0]=$d;}
  else{$D[$i]=$d;}
}
for($j=1;$j<3;$j++){
  for($i=$j+1;$i<10;$i++){
    if($D[$j]<$D[$i]){$d=$D[$i];$D[$i]=$D[$j];$D[$j]=$d;}
  }
}

echo $D[0],PHP_EOL,$D[1],PHP_EOL,$D[2];
?>
