What are the potential risks of using SELECT * in PHP queries and how can they be mitigated?

Using SELECT * in PHP queries can pose security risks as it retrieves all columns from a table, potentially exposing sensitive data. To mitigate this risk, it is recommended to explicitly specify the columns needed in the SELECT statement. 

// Specify the columns needed in the SELECT statement
$query = "SELECT column1, column2, column3 FROM table_name WHERE condition = 'value'";
$result = mysqli_query($connection, $query);

// Fetch the results as needed
while ($row = mysqli_fetch_assoc($result)) {
    // Process the data
}
