How can syntax errors in PHP code affect the functionality of MySQL update operations?

Syntax errors in PHP code can prevent MySQL update operations from executing properly because the PHP script will fail to run, resulting in no changes being made to the database. To solve this issue, it is important to carefully check the syntax of the PHP code, including proper placement of semicolons, parentheses, and quotation marks. 

<?php
// Correcting syntax errors in PHP code to ensure MySQL update operation runs successfully
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// SQL query to update data in MySQL table
$sql = "UPDATE table_name SET column_name = 'new_value' WHERE condition";

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

$conn->close();
?>
