What are some common pitfalls when trying to output the contents of a multidimensional array in PHP without using a loop?

One common pitfall when trying to output the contents of a multidimensional array in PHP without using a loop is attempting to directly echo the array, which will only display the data type of the array. To solve this issue, you can use the `print_r()` or `var_dump()` functions to display the contents of the multidimensional array. 

// Example of outputting the contents of a multidimensional array using print_r()
$multiArray = array(
    array(1, 2, 3),
    array('a', 'b', 'c')
);

echo "<pre>";
print_r($multiArray);
echo "</pre>";
