What are the potential issues with concatenating date and time values in PHP before storing them in a database?

When concatenating date and time values in PHP before storing them in a database, the potential issue is that it may not be in the correct format for the database to interpret as a datetime value. To solve this issue, it is recommended to use PHP's DateTime class to format the date and time properly before storing it in the database. 

// Example of concatenating date and time values and formatting them using DateTime class
$date = "2022-01-01";
$time = "12:00:00";

// Concatenate date and time values
$datetime = $date . ' ' . $time;

// Format the concatenated datetime using DateTime class
$datetime_formatted = DateTime::createFromFormat('Y-m-d H:i:s', $datetime)->format('Y-m-d H:i:s');

// Store $datetime_formatted in the database
// $query = "INSERT INTO table_name (datetime_column) VALUES ('$datetime_formatted')";
