What are the potential pitfalls of using the mysql_fetch_row function in PHP when querying a MySQL database?

Using the mysql_fetch_row function in PHP when querying a MySQL database can be problematic because it returns an enumerated array, making it difficult to access the fetched data by column name. To avoid this issue, you can use the mysql_fetch_assoc function instead, which returns an associative array with column names as keys. 

// Connect to MySQL database
$connection = mysql_connect("localhost", "username", "password");
mysql_select_db("database_name", $connection);

// Query the database
$result = mysql_query("SELECT * FROM table_name");

// Fetch data using mysql_fetch_assoc
while ($row = mysql_fetch_assoc($result)) {
    // Access data by column name
    echo $row['column_name'];
}

// Close the connection
mysql_close($connection);
