How can debugging tools help identify and resolve issues with textareas in PHP forms?

Textareas in PHP forms may encounter issues such as not displaying user input correctly or not saving data properly. Debugging tools like var_dump() or print_r() can help identify where the issue lies, such as incorrect variable names or missing form attributes. By using these tools to print out the values of variables related to the textarea, developers can pinpoint the problem and make the necessary adjustments to resolve it. 

<?php
// Example PHP code snippet to debug and resolve issues with textareas in forms

// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Use var_dump() to display form data for debugging
    var_dump($_POST);
    
    // Retrieve textarea input from form
    $textarea_input = $_POST['textarea_name'];
    
    // Process textarea input further
    // Add your code here to handle the textarea input
    
    // Display success message
    echo "Textarea input saved successfully!";
}
?>

<form method="post" action="">
    <textarea name="textarea_name"></textarea>
