如何获得该类别内所有交易的每个类别的总和

在本例中，类别

部门

的总和为

，类别

费用

的总和为

4'492

但是如何在PHP中实现这一点呢

以下是我当前的代码：

function do_maths($expression) {
    eval('$o = ' . preg_replace('/[^0-9\+\-\*\/\(\)\.]/', '', $expression) . ';');
    return $o;
}

function inifile($fname, $word) {
    $contents = file_get_contents($fname.'.ini');
    $pattern = preg_quote($word, '/');
    $pattern = "/^.*$pattern.*\$/m";

    if(preg_match_all($pattern, $contents, $matches)) {
        sort($matches[0]);

        # TABELL
        echo '<div class="table">';

            # LOOP
            foreach($matches[0] AS $found) {
                $transaction = explode('|', $found);

                echo '<div class="table-row'.($transaction[3] == 1 ? ' color-grey-light" title="'.$transaction[1].' är betalad"' : '"').'>';
                    echo '<div class="table-cell-left table-cell-left-width">';
                        echo $transaction[1];
                    echo '</div>';

                    echo '<div class="table-cell-right">';
                        echo '<span class="sum">';
                            echo do_maths($transaction[2]);
                        echo '</span> kr';
                    echo '</div>';
                echo '</div>';
            }

        echo '</div>';


    } else {
        echo '<div class="message color-blue">';
            echo 'Kunde inte hitta något';
        echo '</div>';
    }
}
