PHPでMYSQLデータベースを転置する方法

この機能を試してください：

function array_transpose($array, $selectKey = false) {
    if (!is_array($array)) return false;
    $return = array();
    foreach($array as $key => $value) {
        if (!is_array($value)) return $array;
        if ($selectKey) {
            if (isset($value[$selectKey])) $return[] = $value[$selectKey];
        } else {
            foreach ($value as $key2 => $value2) {
                $return[$key2][$key] = $value2;
            }
        }
    }
    return $return;
}


$fruits = array(
    array('id' => 1, 'name' => 'Apple', 'color' => 'Red'),
    array('id' => 2, 'name' => 'Orange', 'color' => 'Orange'),
    array('id' => 3, 'name' => 'Mango', 'color' => 'Yellow')
);
echo "<pre>";
print_r(array_transpose($fruits));
echo "</pre>";

返品：

Array
(
    [id] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
        )

    [name] => Array
        (
            [0] => Apple
            [1] => Orange
            [2] => Mango
        )

    [color] => Array
        (
            [0] => Red
            [1] => Orange
            [2] => Yellow
        )

)
