How can I efficiently delete multiple IDs from a database in PHP?

To efficiently delete multiple IDs from a database in PHP, you can use a single SQL query with the IN clause to specify multiple IDs to delete at once. This approach reduces the number of queries sent to the database, improving performance. 

<?php
// Database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Array of IDs to delete
$ids = [1, 2, 3, 4, 5];

// Construct SQL query to delete multiple IDs
$sql = "DELETE FROM your_table_name WHERE id IN (" . implode(',', $ids) . ")";

// Execute query
if ($conn->query($sql) === TRUE) {
    echo "Records deleted successfully";
} else {
    echo "Error deleting records: " . $conn->error;
}

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