In PHP, you can create and assign values to multi-dimensional arrays in the following way:

// 创建一个空的多维数组
$multiDimArray = array();

// 直接赋值
$multiDimArray = array(
    array(1, 2, 3),
    array('a', 'b', 'c'),
    array(true, false)
);

// 动态赋值
$multiDimArray[] = array(4, 5, 6);
$multiDimArray[] = array('d', 'e', 'f');

// 访问多维数组元素
echo $multiDimArray[0][1]; // 输出 2
echo $multiDimArray[1][2]; // 输出 c

Through the methods mentioned above, it is possible to create multi-dimensional arrays and assign values to them as well as access their elements.
