What are the potential issues with accessing specific columns in a MySQL query result in PHP?

When accessing specific columns in a MySQL query result in PHP, potential issues may arise if the column name is misspelled or does not exist in the result set. To avoid these issues, it is recommended to use the `mysqli_fetch_assoc()` function to fetch the result as an associative array and then access the specific column by its name. 

// Assume $result is the result of a MySQL query
while ($row = mysqli_fetch_assoc($result)) {
    // Access specific column by its name
    $columnValue = $row['column_name'];
    // Do something with $columnValue
}
