Solution in PHP (judge verdict: Accepted)

<?php
  $t = array(0,0,0);
  for($i=0; $i<10;$i++) {
      $j = (int)fgets(STDIN);

      if($j>$t[2]) {
          if($j>$t[1]) {
              if($j>$t[0]) {
                  $t[2] = $t[1];
                  $t[1] = $t[0];
                  $t[0] = $j;
              } else {
                  $t[2] = $t[1];
                  $t[1] = $j;
              }
