How can syntax errors in PHP code affect the functionality of database update queries?

Syntax errors in PHP code can prevent database update queries from executing properly. These errors can cause the PHP script to fail before reaching the database query, resulting in no updates being made to the database. To solve this issue, it is important to carefully review the PHP code for syntax errors and correct them before attempting to execute any database update queries. 

<?php
// Correcting syntax errors in PHP code before executing database update query

// Example of correct PHP code with a database update query
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// 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 a record in the database
$sql = "UPDATE users SET email='newemail@example.com' WHERE id=1";

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

$conn->close();
?>
