How can one effectively debug SQL queries in PHP to identify and resolve syntax errors?

To effectively debug SQL queries in PHP to identify and resolve syntax errors, one can utilize error reporting functions such as mysqli_error() to display any errors encountered during query execution. Additionally, using prepared statements can help prevent syntax errors by separating SQL logic from user input. Lastly, echoing out the SQL query before execution can help spot any syntax issues. 

// Example PHP code snippet to debug SQL queries
$sql = "SELECT * FROM users WHERE id = ?";
$stmt = $mysqli->prepare($sql);

if (!$stmt) {
    die("Error in SQL query: " . $mysqli->error);
}

$id = 1;
$stmt->bind_param("i", $id);
$stmt->execute();

$result = $stmt->get_result();

while ($row = $result->fetch_assoc()) {
    // Process results
}

$stmt->close();
$mysqli->close();
