How can PHP developers handle errors related to fetching data from a MySQL database, such as the one mentioned with mysql_fetch_row() in the thread?

When fetching data from a MySQL database using `mysql_fetch_row()`, PHP developers can handle errors by checking if the query was successful before attempting to fetch rows. This can be done by verifying the result of `mysql_query()` and handling any potential errors accordingly. 

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

// Check if the query was successful
if (!$result) {
    die('Error: ' . mysql_error());
}

// Fetch rows from the result
while ($row = mysql_fetch_row($result)) {
    // Process the fetched data
}

// Free the result set
mysql_free_result($result);
