What potential issue is the user experiencing with the mysql_fetch_array function?

The potential issue the user is experiencing with the mysql_fetch_array function is that it is deprecated in newer versions of PHP and has been replaced by mysqli_fetch_array or PDO fetch functions. To solve this issue, the user should switch to using mysqli or PDO for database interactions to ensure compatibility and security.

// Connect to the database using mysqli
$connection = mysqli_connect("localhost", "username", "password", "database");

// Query the database
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);

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