How can PHP developers troubleshoot issues with generating dynamic text output from form inputs?

Issue: PHP developers can troubleshoot issues with generating dynamic text output from form inputs by ensuring that the form data is properly sanitized and validated before using it to generate the output. They should also check for any errors in the code that may be causing the issue, such as syntax errors or incorrect variable names. 

<?php
// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Sanitize and validate form inputs
    $input_text = filter_var($_POST['input_text'], FILTER_SANITIZE_STRING);
    
    // Generate dynamic text output
    $output_text = "Hello, " . $input_text . "!";

    // Display output
    echo $output_text;
}
?>
