How can extra commas in a MySQL query cause syntax errors when using PHP?

Extra commas in a MySQL query can cause syntax errors when using PHP because they are not allowed in SQL syntax. To solve this issue, you need to ensure that there are no unnecessary commas in your query string before executing it. 

// Example of a MySQL query with extra commas causing syntax errors
$query = "SELECT * FROM users WHERE id = 1,";
// Remove any extra commas from the query
$query = rtrim($query, ',');
// Execute the corrected query
$result = mysqli_query($connection, $query);
