How can SQL syntax errors be debugged and resolved in PHP code?

SQL syntax errors in PHP code can be debugged and resolved by carefully examining the SQL query for any syntax mistakes such as missing commas, incorrect table or column names, or improper use of quotation marks. It is also helpful to use error handling functions like mysqli_error() to display any specific error messages from the database. 

// Example PHP code snippet to debug and resolve SQL syntax errors
$sql = "SELECT * FROM users WHERE username = 'john' AND age > 30";
$result = mysqli_query($connection, $sql);

if (!$result) {
    echo "Error: " . mysqli_error($connection);
} else {
    // Process the query result
}
