使用DB PHP中的<td>值生成表行

Question

I am trying to create a dynamically made table that will display multiple drop down lists within each row with previously selected values that are stored within a DB.

Currently I am stuck on just displaying the proper values within each <td>.

//$query..               
$data = mysqli_query($dbc, $query);

echo"<table>
        <tr>
        <th>Component</th>
        <th>Component Type</th>
        <th>Component Thickness</th>
        </tr>";

while ($row = mysqli_fetch_array($data)) { //while I have rows..

    //add column values to an array
    $facSecComponentID[] = $row['facility_section_components_id'];
    $facSecComponent[] = $row['roof_component_id'];
    $facSecComponentType[] = $row['roof_component_type_id'];
    $facSecComponentThickness[] = $row['component_thickness'];

    //try to loop through each index of each row and get the DB value..
    //eventually use this value to assign a selected index within the drop down list
    foreach ($row as $componentIndex => $selectedComponent) {
        echo "<tr>";
        echo "<td>" . $facSecComponent[$selectedComponent] . "</td>";
        echo "<td>" . $facSecComponentType[$selectedComponent] . "</td>";
        echo "<td>" . $facSecComponentThickness[$selectedComponent] . "</td>";
        echo "</tr>";   
    }
}

echo "</table>";

I can't get the values I need here to display properly, I have also tried to do something like: "<td>" . $componentIndex[$selectedComponent] . "</td>"; which didn't help.

I keep getting undefined index errors or all fields being a single value.

Let me know if anything is unclear or needs further explanation and I will try to make my question more clear.

Any help would be great,

Thanks

Try:

$facSecComponentID = array();
$facSecComponent = array();
$facSecComponentType = array();
$facSecComponentThickness = array();

while ($row = mysqli_fetch_array($data)) {
    $facSecComponentID[] = $row['facility_section_components_id'];
    $facSecComponent[] = $row['roof_component_id'];
    $facSecComponentType[] = $row['roof_component_type_id'];
    $facSecComponentThickness[] = $row['component_thickness'];
}

$numItems = mysqli_num_rows($result);

for($i=0;$i<$numItems;$i++){
    echo "<tr>";
    echo "<td>{$facSecComponent[$i]}</td>";
    echo "<td>{$facSecComponentType[$i]}</td>";
    echo "<td>{$facSecComponentThickness[$i]}</td>";
    echo "</tr>";   
}
