What are some common SQL syntax errors to watch out for when updating records in PHP?

Common SQL syntax errors to watch out for when updating records in PHP include missing quotation marks around string values, using reserved keywords as column names without escaping them, and forgetting to include the WHERE clause when updating specific records. To avoid these errors, always use prepared statements with placeholders for values to prevent SQL injection attacks and ensure proper escaping of values. Additionally, double-check your SQL queries for any syntax errors before executing them. 

// Example of updating a record in a database using prepared statements

// Assuming $conn is a valid database connection

$id = 1;
$newValue = "New Value";

$stmt = $conn->prepare("UPDATE table_name SET column_name = ? WHERE id = ?");
$stmt->bind_param("si", $newValue, $id);
$stmt->execute();
$stmt->close();
