What are the advantages of using UPDATE statements over PHP logic for updating data in a SQL table?

Using UPDATE statements in SQL is more efficient and faster than using PHP logic to update data in a SQL table. This is because UPDATE statements are executed directly on the database server, reducing the amount of data transferred between the server and the application. Additionally, UPDATE statements are more concise and easier to read compared to complex PHP logic for updating data. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Update data using SQL UPDATE statement
$sql = "UPDATE table_name SET column1 = 'new_value' WHERE condition";

if ($conn->query($sql) === TRUE) {
    echo "Record updated successfully";
} else {
    echo "Error updating record: " . $conn->error;
}

$conn->close();
?>
