          <select name="score-1" class="score-1">
            <?php
              if(isset($_SESSION['s_score1'])){ //echoes currently set team
              echo $_SESSION['s_score1'];
              }else {
                echo "<option>0</option>
                      <option>1</option>
                      <option>2</option>
                      <option>3</option>
                      <option>4</option>";
              }
            ?>
          </select>


<?php //SETTING SESSION VARIABLES FOR ROUND 1 TEAMS AND SCORE

session_start();

  if (isset($_POST['go1'])) {

    include_once 'dbcon.php';

    $_SESSION['t_team1'] = $_POST['team-1'];
    $_SESSION['t_team2'] = $_POST['team-2'];
    $_SESSION['s_score1'] = $_POST['score-1'];
    $_SESSION['s_score2'] = $_POST['score-2'];
    header("Location: ../tables.php?tables=winner");
}
?>

它基本上用单个空格代替当前会话变量填充选择框我似乎找不到问题

您有条件地打印选项。您应该始终打印选项，并仅将适当的选项标记为“已选择”。

<select name="score-1" class="score-1">
            <?php
                 $val = isset($_SESSION['s_score1']) ? $_SESSION['s_score1'] : false;
                 foreach(range(0,4) as $n) {
                   $selected = $n === $val ? 'selected' : ''; 
                   echo '<option ' .$selected . '>'.$n.'</option>';
                 }
            ?>
          </select>

选择框使用设置的会话回显空白
