How can developers effectively debug and troubleshoot SQL syntax errors in PHP scripts?

When developers encounter SQL syntax errors in PHP scripts, they can effectively debug and troubleshoot by carefully reviewing the SQL query for any syntax mistakes such as missing commas, quotes, or incorrect table/column names. They can also use tools like PHP's built-in error reporting functions or database management tools to pinpoint the exact location of the error. Additionally, developers can echo or log the SQL query to see the generated query and identify any discrepancies. 

// Example PHP code snippet demonstrating how to debug SQL syntax errors
$sql = "SELECT * FROM users WHERE username = 'john' AND email = 'john@example.com'";
$result = mysqli_query($conn, $sql);

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