Question

我有两个变量，例如：

$from = 13:43:13;

$to = 18:53:13;

我需要在PHP中计算$from和$to之间的小时数，以便$total如下：

$total = 5.10 // 5 hours and ten minutes

或

$total = 0.40 // 0 hours and 40 minutes

我不介意秒，我需要的是小时和分钟。

请帮帮我:)。

Answer 1

$from       = '13:43:13';
$to         = '18:53:13';

$total      = strtotime($to) - strtotime($from);
$hours      = floor($total / 60 / 60);
$minutes    = round(($total - ($hours * 60 * 60)) / 60);

echo $hours.'.'.$minutes;

Answer 2

我喜欢使用面向对象的方法，使用DateTime类：

$from = new DateTime('13:43:13');
$to = new DateTime('18:53:13');

echo $from->diff($to)->format('%h.%i'); // 5.10

如何制作一个函数并将下面的代码放入其中？

<?php
    $from = $_REQUEST['start_time']; 
    $to = $_REQUEST['end_time']; 
    $action = $_REQUEST['action']; 
?> 

<? 
    if($action && ($action == "go")){ 
        list($hours, $minutes) = split(':', $from); 
        $startTimestamp = mktime($hours, $minutes); 

        list($hours, $minutes) = split(':', $to); 
        $endTimestamp = mktime($hours, $minutes); 

        $seconds = $endTimestamp - $startTimestamp; 
        $minutes = ($seconds / 60) % 60; 
        $hours = round($seconds / (60 * 60)); 

        echo "Time passed: <b>$hours</b> hours and <b>$minutes</b> minutes"; 
    } 
?>

请添加字段以接收值...
