调用函数 - 如何简化此操作？

Question

I use the following to display a table of soccer fixtures. It works, but is there any way to simplify it with a loop or something?

$con=mysqli_connect("SERVER","USER","PASS", "DATABASE") or die("I'm drunk officer.");

//If blank, make it red. If it has a /, make it green, otherwise normal.   
function gw($week) 
{
if ($week == "") 
{ 
    echo "<td align='center' style='background: #FF0000'>"; 
}
elseif (strpos($week,'/') !== false) 
{ 
    echo "<td align='center' style='background: #00FF00'>"; 
}
else
{
    echo "<td align='center'>";
}
echo $week."</td>";
}


function GetTeamFixtures($team)
        {
            global $con;
            //Pull info from database
            $queryget = mysqli_query($con, "SELECT * FROM `fixtures` WHERE team='$team' LIMIT 1");

            //go through every row
            $row = mysqli_fetch_assoc($queryget);

            //Get the info from the db
            $team = $row['team'];   
            $gw1 = $row['gw1'];

Answer 1

${'gw' . $i} = $row['gw'.$i]; and gw(${'gw' . $i}); with $i being a counter.
