Are there best practices for handling sporadic connection failures in PHP mysqli scripts?

Sporadic connection failures in PHP mysqli scripts can be handled by implementing error handling and retry mechanisms. This can involve catching connection errors, reconnecting to the database, and retrying the failed query. 

<?php

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

if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

$query = "SELECT * FROM table";

// Retry logic for handling sporadic connection failures
$retry = 3;
while ($retry > 0) {
    $result = $mysqli->query($query);
    
    if (!$result) {
        echo "Error: " . $mysqli->error;
        $retry--;
        continue;
    }
    
    // Process the query result here
    
    break;
}

$mysqli->close();

?>
