What are the potential pitfalls of using the @ symbol in front of mysqli functions in PHP code?

Using the @ symbol in front of mysqli functions in PHP code suppresses any error messages or warnings that may occur, making it difficult to troubleshoot and debug issues in the code. It is generally not recommended to use the @ symbol as it can hide important information about potential problems in the code. To solve this issue, it is better to handle errors and exceptions properly using try-catch blocks or error handling functions. 

<?php

// Connect to database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Check for connection errors
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Perform database operations
// ...

// Close the connection
$mysqli->close();

?>
