You have several problems.你有几个问题。

Array indexes start at 0 , not 1 .数组索引从0开始，而不是1 。 But it's usually clearer to use foreach .但通常使用foreach更清晰。
You shouldn't hard-code the array lengths, use count() .您不应该对数组长度进行硬编码，请使用count() 。
You're missing several $ before variable names.你在变量名之前缺少几个$ 。
You're not printing the times from $times .你不是从$times打印$times 。 They should be printed as a header line before the first day.它们应该在第一天之前作为标题行打印。
You shouldn't have $i = $i + 1;你不应该有$i = $i + 1; , as you'll increment $i twice because of $i++ . ，因为你会因为$i++而增加$i两次。

$days = array('Monday', 'Tuesday', 'Wednesday', 'Thurstday', 'Friday');
$times = array('08:00-08:45','09:00-09:45','10:05-10:50','11:05-11:50','12:05-12:50','13:20-14:05','14:20-15:05');
$columns = count($times);

echo "<table border='1'>";
echo "<tr><th>Day</th>;";
foreach ($times as $time) {
    echo "<th>$time</th>";
}
echo "</tr>";
foreach ($days as $day) {
    echo("<tr><th>$day</th>");
    for ($i = 0; $i < $columns; $i++) {
        echo "<td></td>"; // empty fields for each period
    }
}
echo "</tr>";
echo("</table>");
