In what scenarios is it advisable to avoid using SELECT * in MySQL queries in PHP scripts, and what are the potential consequences of doing so?

Avoid using SELECT * in MySQL queries in PHP scripts when you only need specific columns from a table. Using SELECT * can retrieve unnecessary data, leading to increased network traffic and slower query execution. Additionally, it can make the code harder to maintain and prone to errors if the table structure changes. 

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

// Process the query result as needed
while ($row = mysqli_fetch_assoc($result)) {
    // Access specific columns using $row['column_name']
}
