What are the potential reasons for mysql_fetch_array and mysql_fetch_object not working as expected in PHP?

The potential reasons for `mysql_fetch_array` and `mysql_fetch_object` not working as expected in PHP could be due to deprecated functions, compatibility issues with newer versions of PHP, or incorrect usage of these functions. To solve this issue, it is recommended to switch to using `mysqli_fetch_array` or `mysqli_fetch_object` functions instead, as the `mysql_` functions have been deprecated in newer PHP versions. 

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

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

// Fetch data as an array
while ($row = mysqli_fetch_array($result)) {
    // Process each row
    print_r($row);
}

// Fetch data as an object
while ($row = mysqli_fetch_object($result)) {
    // Process each row
    echo $row->column_name;
}

// Close the connection
mysqli_close($connection);
