How can the error messages related to invalid MySQL result resources be resolved in PHP?

When working with MySQL result resources in PHP, it is important to check if the result is valid before attempting to use it. If an invalid result resource is used, it can lead to errors such as "Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given". To resolve this issue, you can check if the result is valid before using it in your code. 

// Check if the result is valid before using it
if ($result && mysql_num_rows($result) > 0) {
    while ($row = mysql_fetch_array($result)) {
        // Process the data
    }
} else {
    echo "Invalid result resource";
}
