What are common reasons for a PHP script to lose connection to a database?

Common reasons for a PHP script to lose connection to a database include network issues, server timeouts, incorrect database credentials, or exceeding the maximum number of allowed connections. To solve this issue, you can implement error handling and reconnect to the database if the connection is lost. 

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

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

// Reconnect if connection is lost
if ($conn->ping() === false) {
    $conn->close();
    $conn = new mysqli($servername, $username, $password, $dbname);
}

// Use the $conn object for database operations
?>
