What are the common issues with using Unix timestamps in PHP for MySQL database entries?

When using Unix timestamps in PHP for MySQL database entries, a common issue is that Unix timestamps are stored as integers, which can lead to potential errors when querying or manipulating the data. To solve this issue, it is recommended to convert Unix timestamps to MySQL DATETIME format before storing them in the database. This ensures that the data is stored in a format that is easily readable and manipulable.

// Convert Unix timestamp to MySQL DATETIME format
$unixTimestamp = time();
$mysqlDatetime = date('Y-m-d H:i:s', $unixTimestamp);

// Insert the converted DATETIME value into the database
$query = "INSERT INTO table_name (timestamp_column) VALUES ('$mysqlDatetime')";
mysqli_query($connection, $query);
