如何将double值转换为时间？

Question

How can I convert a double value to time? For example, if the input is 7.50 then the output would be 7.30.

Answer 1

$input = "7.5";
list($hours, $wrongMinutes) = explode('.', $input);
$minutes = ($wrongMinutes < 10 ? $wrongMinutes * 10 : $wrongMinutes) * 0.6;
echo $hours . ':' . $minutes;
