How can PHP developers efficiently manage and update individual database entries through a dynamic admin interface without affecting other entries?

To efficiently manage and update individual database entries through a dynamic admin interface without affecting other entries, PHP developers can implement a CRUD (Create, Read, Update, Delete) system. This system allows developers to interact with the database in a structured manner, ensuring that only the specified entry is modified or deleted. By using SQL queries with specific WHERE clauses, developers can target and update individual entries without affecting others. 

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

// Update a specific entry in the database
$id = $_POST['id'];
$new_value = $_POST['new_value'];

$sql = "UPDATE table_name SET column_name = '$new_value' WHERE id = $id";
if ($conn->query($sql) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}

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