What are common issues when using mysql_fetch_array in PHP?

Common issues when using mysql_fetch_array in PHP include not checking if there are any rows returned before trying to fetch data, and not handling the data properly if there are null values. To solve these issues, always check if there are rows returned before fetching data, and handle null values appropriately to avoid errors. 

$result = mysql_query("SELECT * FROM table");

if(mysql_num_rows($result) > 0) {
    while($row = mysql_fetch_array($result)) {
        // Handle data here
    }
} else {
    echo "No rows returned";
}
