What are effective strategies for maintaining data integrity when updating database rows with non-sequential IDs in PHP?

When updating database rows with non-sequential IDs in PHP, it is important to ensure data integrity by properly identifying the rows to be updated. One effective strategy is to use a unique identifier, such as a primary key or another unique column, to select the specific row for updating. This way, you can avoid any potential issues with non-sequential IDs and ensure that the correct row is updated. 

<?php
// Assuming $db is your database connection object
$id = 5; // Non-sequential ID of the row to be updated
$newValue = 'Updated Value';

// Select the row based on a unique identifier (e.g. primary key)
$stmt = $db->prepare("UPDATE your_table SET your_column = :value WHERE id = :id");
$stmt->bindParam(':value', $newValue);
$stmt->bindParam(':id', $id);
$stmt->execute();
?>
