What are the potential pitfalls of using "Select *" in MySQL queries for fetching data in PHP scripts?

Using "Select *" in MySQL queries can lead to performance issues and security vulnerabilities in PHP scripts. It is recommended to explicitly specify the columns you want to fetch to improve query performance and prevent exposing sensitive data. Additionally, using "Select *" can make the code harder to maintain and understand. 

// Explicitly specify the columns you want to fetch
$query = "SELECT column1, column2, column3 FROM table_name WHERE condition";
$result = mysqli_query($connection, $query);

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