How can syntax errors be avoided when updating a MySQL value in PHP?

Syntax errors when updating a MySQL value in PHP can be avoided by properly constructing the SQL query string with the correct syntax. This includes using the correct SQL keywords, properly escaping variables to prevent SQL injection, and ensuring that the query is properly formatted. 

// Avoiding syntax errors when updating a MySQL value in PHP

// Connect to the database
$connection = new mysqli("localhost", "username", "password", "database");

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

// Update a value in the database
$value = "new value";
$id = 1;

$sql = "UPDATE table_name SET column_name = '" . $connection->real_escape_string($value) . "' WHERE id = " . $id;

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

// Close connection
$connection->close();
