How can PHP developers effectively convert time input in hh:mm format to mm:ss format before storing it in a database?

To convert time input in hh:mm format to mm:ss format before storing it in a database, PHP developers can use the strtotime() and date() functions to manipulate the time format. By converting the input time to a timestamp using strtotime() and then formatting it to mm:ss using date(), developers can effectively convert the time input.

$input_time = "10:30";
$timestamp = strtotime($input_time);
$converted_time = date('i:s', $timestamp);

// Now $converted_time will hold the time in mm:ss format
// Store $converted_time in the database
