How can the issue of "mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource" be resolved in PHP code?

The issue "mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource" typically occurs when the query execution fails or returns an error in MySQL. To resolve this issue, you need to check if the query execution was successful before trying to fetch the results using mysql_fetch_assoc(). 

// Check if the query execution was successful
$result = mysql_query($query);
if (!$result) {

}

// Fetch the results using mysql_fetch_assoc()
while ($row = mysql_fetch_assoc($result)) {
    // Process the results
}
