How can you check if a value in an array is an array in PHP?

To check if a value in an array is an array in PHP, you can use the `is_array()` function. This function takes a variable as a parameter and returns true if the variable is an array, and false otherwise. By using this function, you can easily determine if a specific value in an array is itself an array. 

$value = $array[$index]; // get the value from the array
if (is_array($value)) {
    echo "The value is an array.";
} else {
    echo "The value is not an array.";
}
