php - 使用 PHP 和 MYSQL 创建数据透视表 - 当前显示的表重复标签

Question

我希望获得一些有关如何修改 PHP 代码以在 HTML 中显示数据透视表的帮助。现在，它创建了一个表，每行包含位置、组件和计数，但我宁愿将位置作为列标题，将组件作为行标题，而计数作为数据。

这是我的代码:

function print_table_commodity_location_count_inbd_pivot(){
    $query_items = "SELECT `tbl_origin_dest`.`name` AS 'Location',
                    `tbl_component`.`component_name` AS 'Component',
                    COUNT(`tbl_entry_item`.`entry_item_id`) AS 'Comp_Count'
            FROM tbl_entry
                LEFT JOIN tbl_entry_item ON `tbl_entry`.`entry_id`=`tbl_entry_item`.`entry_id`
                LEFT JOIN tbl_customer ON `tbl_entry`.`customer_id`=`tbl_customer`.`customer_id`
                LEFT JOIN tbl_serv_prov ON `tbl_entry`.`serv_prov_id`=`tbl_serv_prov`.`serv_prov_id`
                LEFT JOIN tbl_origin_dest ON `tbl_entry`.`location`=`tbl_origin_dest`.`id`
                LEFT JOIN tbl_project ON `tbl_entry`.`project_id`=`tbl_project`.`project_id`
                LEFT JOIN tbl_component ON `tbl_entry_item`.`component_id`=`tbl_component`.`component_id`
            WHERE `tbl_entry`.`in_out_type`='I' AND `outbound_entry_id` IS NULL AND `outbound_entry_item_id` IS NULL
            GROUP BY `tbl_origin_dest`.`name`,
                    `tbl_component`.`component_name`";                  

    $result_items=mysql_query($query_items);
    $num_items=mysql_numrows($result_items);

    echo "<table style=\"background-color: silver;\" border=\"1\" cellpadding=\"1\" cellspacing=\"1\">
        <tbody>
            <tr>
                <td><font face=\"Arial, Helvetica, sans-serif\">Location</font></td>
                <td><font face=\"Arial, Helvetica, sans-serif\">Component</font></td>
                <td><font face=\"Arial, Helvetica, sans-serif\">Inventory Count</font></td>
            </tr>"; 
    $x=0;
    while ($x < $num_items) {
        $x1=mysql_result($result_items,$x,"Location");
        $x2=mysql_result($result_items,$x,"Component");
        $x3=mysql_result($result_items,$x,"Comp_Count");

        echo "<tr>
            <td><font face=\"Arial, Helvetica, sans-serif\">".$x1."</font></td>
            <td><font face=\"Arial, Helvetica, sans-serif\">".$x2."</font></td>
            <td><font face=\"Arial, Helvetica, sans-serif\">".$x3."</font></td>
        </tr>";

        $x++;
    }
    echo "</table>";
}

截至目前的结果显示位置 - 组件 - 每行计数。

function print_table_commodity_location_count_inbd_pivot(){
    $query_items = "SELECT `tbl_origin_dest`.`name` AS 'Location',
                    `tbl_component`.`component_name` AS 'Component',
                    COUNT(`tbl_entry_item`.`entry_item_id`) AS 'Comp_Count'

    $result_items=mysql_query($query_items);
        $locationArray = array();
        $components = array()
        echo '<table style=\"background-color: silver;\" border=\"1\" cellpadding=\"1\" cellspacing=\"1\">
                <tbody><tr><td></td>';
        $locations = array();
                while($row = mysql_fetch_assoc($result_items)){
        //create an array with all the locations
        if(!in_array($row['Location'], $locations){
        $locations[] = $row['Location'];
        }
        //create an array for every component and the count at a location
        $components[$row['Component']][$row['Location']] = $row['Comp_count'];


        }
            //create the first row columnns (header)
            foreach($locations as $location){
            echo '<td>'.$location.'</td>'
            }
            echo '</tr>';
            foreach($components as $component => $componentLocations){
                echo '<tr><td>'.$component.'</td>';
                foreach($locations as $loc){
                    //if there is no component at this location
                if(!array_key_exists($loc, $componentLocations)){
                echo '<td>0</td>';
                }else{
                echo '<td>'.$componentLocations[$loc].'</td>';
                }
                }
            echo .'</tr>';
            }
     echo '</tbody></table>';

应该是这样
