How can the use of multiple SET statements in an UPDATE query affect the outcome in PHP?

Using multiple SET statements in an UPDATE query can update multiple columns in a single query. This can be more efficient than making multiple separate UPDATE queries. To use multiple SET statements, separate each column update with a comma in the SET clause of the UPDATE query. 

<?php
// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Update multiple columns in a single query
$stmt = $pdo->prepare("UPDATE mytable SET column1 = :value1, column2 = :value2 WHERE id = :id");
$stmt->execute(array(':value1' => 'new_value1', ':value2' => 'new_value2', ':id' => 1));
