How can the next auto_increment value be retrieved in a MySQL database using PHP without causing gaps in the ID sequence?

When retrieving the next auto_increment value in a MySQL database using PHP, it is important to avoid causing gaps in the ID sequence. One way to achieve this is by using the `SHOW TABLE STATUS` query to get the current auto_increment value for the table, then incrementing it by 1 to get the next value without actually inserting a new row into the table. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";
$conn = new mysqli($servername, $username, $password, $dbname);

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

// Get the next auto_increment value for a table without causing gaps
$result = $conn->query("SHOW TABLE STATUS LIKE 'your_table_name'");
$row = $result->fetch_assoc();
$next_auto_increment = $row['Auto_increment'];

echo "Next auto_increment value: " . $next_auto_increment;

// Close the connection
$conn->close();
?>
