What are some common errors to watch out for when passing arrays to PHP pages?

One common error when passing arrays to PHP pages is not properly encoding the array before sending it. To avoid this issue, you can use functions like `json_encode()` to convert the array to a JSON string before passing it to the PHP page. Another error is not decoding the array correctly on the receiving end. You can use `json_decode()` to convert the JSON string back to an array in PHP. 

// Encoding the array before sending it
$array = [1, 2, 3];
$jsonArray = json_encode($array);
// Send $jsonArray to the PHP page

// Decoding the array on the receiving end
$jsonArray = $_POST['jsonArray']; // Assuming the JSON string is sent via POST
$array = json_decode($jsonArray, true); // true parameter to return an associative array
