How can the error message "supplied argument is not a valid MySQL result resource" be resolved when using mysql_fetch_object() in PHP scripts?

The error message "supplied argument is not a valid MySQL result resource" typically occurs when the query executed by mysql_query() fails to return a valid result set, which then causes mysql_fetch_object() to fail. To resolve this issue, you should check if the query was successful before using mysql_fetch_object() to fetch the results. 

// Check if the query was successful before fetching the results
$result = mysql_query($query);
if($result){
    while($row = mysql_fetch_object($result)){
        // Process each row here
    }
} else {
    echo "Error: " . mysql_error();
}
