What are the best practices for avoiding the use of SELECT * in MySQL queries in PHP?

Using SELECT * in MySQL queries in PHP is not recommended as it can lead to inefficient queries and unnecessary data retrieval, which can impact performance. To avoid this, it is best practice to specify the specific columns you need in the SELECT statement. 

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

// Fetch and process the results
if (mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_assoc($result)) {
        // Process the data
    }
}
