我有一个页面，它从数据库中获取信息并将其显示在表格中。它确实有效，但它非常麻烦。

//Table header here
echo "<tr><td>".$teamname."</td>";

//For Gameweek 7
if ($gw7 == "") 
{ 
    //The team has no game - highlight the cell in red
    echo "<td align='center' style='background: #FF0000'>"; 
}
    elseif (strpos($gw7,'/') !== false) 
{ 
    //The team has 2 games this week - highlight it in green
    echo "<td align='center' style='background: #00FF00'>"; 
}
else
{
    //this means the team has a single game this week - normal cell.
    echo "<td align='center'>";
}
echo $gw7."</td>";
echo "</tr>";

//for gameweek 8 to 36, the above for loop is just repeated (mostly copy/pasted)

//Table footer here

有更清洁的方法吗？我不喜欢多次复制/粘贴相同的代码。

比赛周称为$gw7、$gw8、等$gw9，$gw10并以文本格式包含球队面临的对手。$gw7 中的 7 代表本赛季的第 7 套比赛。它们被分组到游戏周中。如果不清楚，请告诉我。

 $team_array=array("team1","team2","team3","team4"); //as many teams you want
 foreach($team_array as $teamname)
 {
    $rows=getfixturesfromdb($teamname);
    //if fixtures are like $rows['gw1'],$rows['gw2']....etc
    foreach($row as  $gw)
    {
       echo "<tr><td>".$teamname."</td>";
       if ($gw == "") 
     { 
          //The team has no game - highlight the cell in red
          echo "<td align='center' style='background: #FF0000'>"; 
     }
         elseif (strpos($gw,'/') !== false) 
     { 
        //The team has 2 games this week - highlight it in green
        echo "<td align='center' style='background: #00FF00'>"; 
      }
        else
      {

         echo "</tr>";

像这样创建函数

function gw($week) {
    //For Gameweek 7
    if ($week == "") 
    { 
        //The team has no game - highlight the cell in red
        echo "<td align='center' style='background: #FF0000'>"; 
    }
    elseif (strpos($week,'/') !== false) 
    { 
        //The team has 2 games this week - highlight it in green
        echo "<td align='center' style='background: #00FF00'>"; 
    }
    else
    {
        //this means the team has a single game this week - normal cell.
        echo "<td align='center'>";
    }
    echo $week."</td>";
}

//Table header here
echo "<tr><td>".$teamname."</td>";
gw($gw7); // call here function for $gw7 for others as well
echo "</tr>";

您将游戏周放在一个数组中，遍历并调用数组索引高于 6 的自定义代码。

function table_cell($color) {
    echo "<td align='center' style='background: $color'>"; 
}

//Table header here
echo "<tr><td>".$teamname."</td>";

//For Gameweek 7
if ($gw7 == "") 
{ 
    table_cell('#FF0000');
    //The team has no game - highlight the cell in red

}
    elseif (strpos($gw7,'/') !== false) 
{ 
    table_cell('#00FF00');
    //The team has 2 games this week - highlight it in green
}
else
{
    //this means the team has a single game this week - normal cell.
    echo "<td align='center'>";
}
echo $gw7."</td>";
echo "</tr>";
