What are the key differences between using try/catch blocks and if/else statements for error handling in PHP code, especially when dealing with database operations?

When dealing with database operations in PHP code, using try/catch blocks for error handling is generally preferred over if/else statements. Try/catch blocks provide a more structured and organized way to handle exceptions and errors that may arise during database operations. They also allow for more specific and detailed error messages to be captured and handled accordingly. 

try {
    // Database connection and query execution
    $db = new PDO("mysql:host=localhost;dbname=myDB", "username", "password");
    $stmt = $db->prepare("SELECT * FROM myTable");
    $stmt->execute();
    
    // Process the results
    while ($row = $stmt->fetch()) {
        // Do something with the data
    }
} catch (PDOException $e) {
    // Handle any database-related exceptions
    echo "Database Error: " . $e->getMessage();
}
