In PHP, how can one convert multiple arrays into a multidimensional array?

To convert multiple arrays into a multidimensional array in PHP, you can use the array_merge function to merge the arrays together. This will create a new array where each original array becomes a sub-array within the multidimensional array. 

$array1 = [1, 2, 3];
$array2 = ['a', 'b', 'c'];
$array3 = ['x', 'y', 'z'];

$multiArray = [$array1, $array2, $array3];

print_r($multiArray);
