Is it advisable to avoid using SELECT * in MySQL queries in PHP?

Using SELECT * in MySQL queries is generally not advisable because it can retrieve unnecessary columns, leading to inefficiency and potentially exposing sensitive data. It is better to explicitly specify the columns you need in the SELECT statement. This practice improves query performance and makes it easier to understand the code. 

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

if ($result) {
    // Process the query result
} else {
    // Handle the query error
}
