How can an error in a SQL query be identified and resolved in PHP?

To identify and resolve an error in a SQL query in PHP, you can use the mysqli_error() function to retrieve the error message generated by the most recent MySQL function call. This can help you pinpoint the issue in your SQL query and make necessary corrections. 

// Perform a query
$query = "SELECT * FROM users WHERE id = 1";
$result = mysqli_query($connection, $query);

// Check for errors
if (!$result) {
    echo "Error: " . mysqli_error($connection);
} else {
    // Process the query result
}
