What are common syntax errors in SQL queries when updating data using PHP?

Common syntax errors in SQL queries when updating data using PHP include missing quotation marks around string values, incorrect table or column names, and forgetting to use the SET keyword before specifying the columns to update. To solve these issues, always double-check the syntax of your SQL query and use prepared statements to prevent SQL injection attacks. 

// Example of updating data in a table using PHP with correct syntax

// Assuming $conn is the database connection object

// Define the update query with proper syntax
$sql = "UPDATE users SET username = :username, email = :email WHERE id = :id";

// Prepare the statement
$stmt = $conn->prepare($sql);

// Bind parameters
$stmt->bindParam(':username', $username);
$stmt->bindParam(':email', $email);
$stmt->bindParam(':id', $id);

// Execute the statement
$stmt->execute();
