用php和html创建表

Question

I'm basically trying to perform a calculation with the first row and first column however I can't seem to get it working correctly.

function tableCreator($height_arrayy, $weight_arrayy) {


    echo "<table><tr><th></th>";

    foreach($height_arrayy as $value1) {

        echo "<th>$value1</th>";

    }

    echo "</tr>";



    foreach($weight_arrayy as $value2) {

        echo "<tr>";

        echo "<td>$value2</td>";

            foreach($weight_arrayy as $value3) {
                foreach($height_arrayy as $value4) {

                echo "<td>" . ($value3) / ( pow( ($value4 / 100), 2 ) ) . "</td>";

                }
            }

        echo "</tr>";


    }

    echo "</table>";



}       

Result I am getting:

Answer 1

you have added an un-necessary foreach loop, update your second foreach loop as below

foreach($weight_arrayy as $value2) {
    echo "<tr>";
    echo "<th>$value2</th>";
    foreach($height_arrayy as $value4) {
        echo "<td>" . ($value2) / ( pow( ($value4 / 100), 2 ) ) . "</td>";
    }
    echo "</tr>";
}

your code will return desired output. use round() if you want to round upto 2 or 3 decimal points.
