What are common syntax errors to watch out for when constructing MySQL queries in PHP?

Common syntax errors to watch out for when constructing MySQL queries in PHP include missing semicolons at the end of queries, incorrect quoting of strings or identifiers, and missing commas between columns or values in INSERT queries. To avoid these errors, always double-check the syntax of your queries and use prepared statements to prevent SQL injection attacks. 

// Incorrect query with missing semicolon
$query = "SELECT * FROM users WHERE id = 1"
$result = mysqli_query($connection, $query); // Missing semicolon

// Corrected query with semicolon at the end
$query = "SELECT * FROM users WHERE id = 1;";
$result = mysqli_query($connection, $query);
