What error message did the user receive when trying to use each() in the code snippet?

The issue is that the `each()` function is deprecated in PHP 7.2 and removed in PHP 7.3. To solve this issue, you should use a `foreach` loop instead to iterate over arrays. Here is a PHP code snippet that replaces the `each()` function with a `foreach` loop: 

$colors = array("red", "green", "blue");
foreach ($colors as $key => $value) {
    echo "Key: $key, Value: $value<br>";
}
