How can one troubleshoot and debug issues with PDO Prepared Statements in PHP?

Issue: To troubleshoot and debug issues with PDO Prepared Statements in PHP, you can enable error reporting, check for syntax errors in your SQL query, ensure proper binding of parameters, and use try-catch blocks to catch exceptions. 

<?php
// Enable error reporting
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

// Create a PDO connection
$pdo = new PDO('mysql:host=localhost;dbname=database', 'username', 'password');

// Prepare and execute a SQL query with parameters
$stmt = $pdo->prepare('SELECT * FROM table WHERE id = :id');
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$id = 1;
$stmt->execute();

// Fetch results
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);

// Handle exceptions
try {
    // Your code here
} catch (PDOException $e) {
    echo 'Error: ' . $e->getMessage();
}
?>
