問題

私が直面している問題は、expected_weight から動的に損失を差し引くことができないことです。playing_dates カウントが終了するまで expected_weight を変更したい。期待される出力を参照してください。前もって感謝します！

コード：

echo "<pre>";
        $benchmark = 96.5; //The first weight from which a person commits to lose their weight every week.
        $lose = 10; //Percentage of how much they commit to lose
        $lose_weight = ($benchmark/100)*$lose; //This gives how much they should lose every week to meet the target

        while($row_teams = mysql_fetch_assoc($result_select_teams)){
            echo"   {<br />";
            echo"       benchmark ==> ".$benchmark." Kg<br />";
            echo"       loss% ==> ".$lose."%<br />";
            echo"       lose_weight ==> ".$lose_weight." Kg<br /><br />";
            echo"       my_teams ==> ".$row_teams['t_name']."<br /><br />";
            $playing_dates = $row_teams['playing_dates'];
            $playing_dates = explode('|', $playing_dates);

            $date = date('Y');
            $noofweighins = count($playing_dates);
            echo"       noofweighins ==> ".$noofweighins."<br /><br />";
            $lose_atleast = round($lose_weight/$noofweighins, 2);
            $expected_weight = 0;
                for($k=0; $k<count($playing_dates);$k++){
                    $expected_weight = $benchmark - $lose_atleast;
                    if(substr($playing_dates[$k], -4)<=$date){
                        echo"       my_playing_dates ==> ".$playing_dates[$k]." to lose ==> ".$lose_atleast."<br />";
                        echo"       Expected weight ==> ".$expected_weight."<br /><br />";
                    }
                }
            echo"   }<br />";
        }
    }
    echo "</pre>";

$expected_weight = $benchmark - $lose_atleast;私はPHPなどを本当に知りません。コードをざっと読んだだけですが、次のように変更するとどうなりますか$expected_weight = $expected_weight - $lose_atleast;

望ましい結果は次のとおりです。 Expected weight ==> 87.815 (88.78 - 0.965)

$benchmark = 96.5;ずっと変わらないまま。

そして、その式は次のとおりです。 $expected_weight = $benchmark - $lose_atleast;

$benchmark目的の結果を得るには、ループ内を変更する必要があるようです。
