How can PHP developers effectively troubleshoot issues related to querying and comparing timestamps in MySQL tables?

When querying and comparing timestamps in MySQL tables, PHP developers can effectively troubleshoot issues by ensuring that the timestamp format is consistent between the PHP code and the MySQL database. They should also check for timezone differences and handle any conversions accordingly. Additionally, using functions like strtotime() and date() can help manipulate timestamps accurately. 

// Example code snippet to query and compare timestamps in MySQL tables

// Assuming $mysqli is your MySQL connection object

// Query to retrieve timestamp from MySQL table
$query = "SELECT timestamp_column FROM your_table WHERE condition = 'something'";
$result = $mysqli->query($query);

if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        // Comparing timestamps
        $timestamp = strtotime($row['timestamp_column']);
        $currentTimestamp = time();

        if ($timestamp > $currentTimestamp) {
            echo "Timestamp is in the future";
        } else {
            echo "Timestamp is in the past";
        }
    }
} else {
    echo "No results found";
}
