How can the mysql_error() function be utilized to determine the success of a query execution in PHP?

To determine the success of a query execution in PHP, you can utilize the `mysql_error()` function to check for any errors returned by the database. If the function returns an empty string, it means the query executed successfully. If it returns an error message, then there was an issue with the query execution. 

// Execute the query
$result = mysql_query($query);

// Check for errors
if(!$result){
    echo "Query failed: " . mysql_error();
} else {
    echo "Query executed successfully!";
}
