What is the correct syntax for generating a timestamp with mktime in PHP?

When using mktime in PHP to generate a timestamp, the correct syntax involves specifying the hour, minute, second, month, day, and year parameters in that order. It is important to note that mktime uses a 24-hour format for the time parameter. To generate a timestamp, you can use mktime(hour, minute, second, month, day, year).

// Generate a timestamp for a specific date and time
$timestamp = mktime(12, 30, 0, 6, 15, 2022);
echo $timestamp;
