How can a beginner effectively troubleshoot and debug PHP code when trying to display API data in an HTML table?

To effectively troubleshoot and debug PHP code when trying to display API data in an HTML table, beginners can start by checking for any syntax errors, ensuring that the API is properly accessed and returning data, and verifying that the data is being processed correctly before being displayed in the HTML table.

<?php
// Sample PHP code to display API data in an HTML table

// Make API request to retrieve data
$response = file_get_contents('https://api.example.com/data');
$data = json_decode($response, true);

// Check if data is successfully retrieved
if ($data) {
    // Display data in an HTML table
    echo '<table>';
    foreach ($data as $row) {
        echo '<tr>';
        foreach ($row as $value) {
            echo '<td>' . $value . '</td>';
        }
        echo '</tr>';
    }
    echo '</table>';
} else {
    echo 'Error retrieving data from API.';
}
?>
