How can the UPDATE SQL command be effectively applied to edit entries in a database in PHP?

To edit entries in a database using the UPDATE SQL command in PHP, you need to establish a database connection, construct the SQL query with the updated values, and execute the query using a prepared statement. Make sure to bind the parameters to prevent SQL injection attacks. Finally, execute the statement to update the database entry. 

<?php
// Establish database connection
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');

// Prepare UPDATE SQL query
$stmt = $pdo->prepare("UPDATE table_name SET column1 = :value1, column2 = :value2 WHERE id = :id");

// Bind parameters
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);
$stmt->bindParam(':id', $id);

// Set values for parameters
$value1 = 'new_value1';
$value2 = 'new_value2';
$id = 1;

// Execute query
$stmt->execute();
?>
