How can the use of PHP functions like strtotime impact the accuracy of date values when inserting into a SQL table?

When using PHP functions like strtotime to convert date values, there can be issues with accuracy due to differences in date formats and timezones. To ensure accurate date values when inserting into a SQL table, it is recommended to use the SQL standard date format (YYYY-MM-DD) and handle timezone conversions appropriately.

$date = "2022-01-20"; // Sample date value
$timestamp = strtotime($date);
$mysql_date = date("Y-m-d", $timestamp);

// Insert $mysql_date into SQL table
