これはMySQLの私のデータです（sqlfiddle.com）

そしてこれは私のPHPコードです：

<?php
   $setting_tahunajaranget = $_GET['setting_tahunajaran'];
   $setting_kodepraktikumget = $_GET['setting_kodepraktikum'];
   $nama_praktikum = $_GET['nama_praktikum'];
   $setting_semesterget = $_GET['setting_semester'];

$query2 = "SELECT `nilai` AS semester FROM `nilaipraktikum` WHERE `modulke`= 0 LIMIT 0, 30 ";
$data   = mysql_fetch_row(mysql_query($query2));
        $query = "SELECT `idpraktikan`,namauser,`modulke`, `nilai`,`status_tugasakhir`,`tahunajaran`,`semester` FROM `nilaipraktikum` LEFT JOIN tabeluser ON tabeluser.npmuser = nilaipraktikum.idpraktikan WHERE `tahunajaran` = '$setting_tahunajaranget' AND`kodepraktikum` = '$setting_kodepraktikumget' AND `semester` = '$setting_semesterget' ";


        $result = mysql_query($query);
    if ($data = mysql_fetch_row($result)>=1)
    {

   $nilai   =   $data['nilai'];
        if ($nilai = $setting_semesterget);

echo "</table>";
            echo "<br/> <a href='javascript:history.back()'>Klik Disini Untuk Kembali</a>";

    }    
?>

私の質問ですが、なぜRata-Rata（平均的なNILAI）の列で、配列の結果を前の配列の結果と合計したのですか？詳しくはこちらの写真をご覧ください。（リンク画像：https ：//www.diigo.com/item/image/3gviv/3m98？size = o ）

一方、結果はこの写真のような列を平均したいと思います。（リンク画像：https ：//www.diigo.com/item/image/3gviv/6ke4？size = o ）

私のスクリプトの何が問題になっていますか？

注意：列Nilai Tugas AkhirNilaiAkhirグレードはまだ修正されていません。

初期化変数を追加するだけです

$nilaimodul = 0; // try adding this to your code
for($i=1;$i<=$jml_modul;$i++) 
{
    echo "<td align='center' valign='middle'>".$array_nilai[$nim][$i]."</td>"; 
    $nilaimodul += (array_sum(array($array_nilai[$nim][$i])));
}
$ratarata = ($nilaimodul);
