What are the advantages of defining timestamps in PHP variables rather than relying on MySQL functions like NOW()?

Defining timestamps in PHP variables rather than relying on MySQL functions like NOW() allows for more flexibility and control over the timestamp format and timezone. It also makes the code more portable and easier to debug, as the timestamp generation is handled within the PHP script itself. Additionally, by defining timestamps in PHP variables, you can easily manipulate and format the timestamps before inserting them into the database. 

// Define timestamp in PHP variable
$timestamp = date('Y-m-d H:i:s');

// Insert data into database with PHP variable
$query = "INSERT INTO table_name (timestamp_column) VALUES ('$timestamp')";
$result = mysqli_query($connection, $query);

// Retrieve data from database with PHP variable
$query = "SELECT * FROM table_name WHERE timestamp_column = '$timestamp'";
$result = mysqli_query($connection, $query);
