Why is the code not functioning as expected when checking for messages in PHP?

The code may not be functioning as expected when checking for messages in PHP due to syntax errors, incorrect logic, or missing variables. To solve this issue, ensure that the code is properly structured, the logic for checking messages is correctly implemented, and all necessary variables are defined and initialized. 

// Example code snippet to check for messages in PHP
$messages = []; // Initialize an empty array to store messages

// Check if the form has been submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Check if the message field is not empty
    if (!empty($_POST["message"])) {
        // Add the message to the array
        $messages[] = $_POST["message"];
    } else {
        echo "Message field is empty.";
    }
}

// Display all messages
foreach ($messages as $message) {
    echo $message . "<br>";
}
