How can you append a new two-dimensional array to an existing array in PHP?

To append a new two-dimensional array to an existing array in PHP, you can use the array_merge function. This function merges two or more arrays together, creating a new array with values from both arrays. By using this function, you can easily add a new two-dimensional array to an existing array without overwriting any existing data. 

// Existing array
$existingArray = array(
    array('a', 'b', 'c'),
    array('d', 'e', 'f')
);

// New two-dimensional array to append
$newArray = array(
    array('g', 'h', 'i'),
    array('j', 'k', 'l')
);

// Append the new two-dimensional array to the existing array
$mergedArray = array_merge($existingArray, $newArray);

// Output the merged array
print_r($mergedArray);
