The datefunction is your friend:
该日期的功能是你的朋友：
Given your own code above:
鉴于上面你自己的代码：
$yourdatetime = "04:04:07";
$timestamp = strtotime($yourdatetime);
You can then feed it into the date function:
然后，您可以将其输入到日期函数中：
echo 'Hours:' . date('h', $timestamp); // Hours: 04
echo 'Minutes:' . date('i', $timestamp); // Minutes: 04
echo 'Seconds:' . date('s', $timestamp); // Seconds: 07
Refer to the docsfor the specific format(s) you'd like for hours - there's many options.
请参阅文档以了解您想要几个小时的特定格式 - 有很多选择。
You could even do it in one move:
你甚至可以一步完成：
echo date('h.i', $timestamp); // 04.04
If you need it truly numeric:
如果你需要它真正的数字：
echo float(date('h.i', $timestamp)); // 4.04

strtotime()returns the time in seconds since the Unix Epoch. You can then format this using date(). Documentation for date: http://php.net/manual/en/function.date.php
strtotime()返回自 Unix 纪元以来的时间（以秒为单位）。然后，您可以使用date(). 日期文档：http: //php.net/manual/en/function.date.php
To get the number of hours (4):
获取小时数 (4)：
$timestamp = date("g",strtotime($yourdatetime));
To get the number of hours and minutes (4.03):
获取小时数和分钟数 (4.03)：
$timestamp = date("g.i",strtotime($yourdatetime));

Use (float)and preg_replaceto one-line-code conversion:
使用(float)和preg_replace到一行代码转换：
$floatval = (float) preg_replace('/^(\d+):(\d+).+/','.',$yourdatetime);

So we'll break this out. If we cast the hours as an integer and leave the minutes as a string this is a pretty simple conversion
所以我们会打破这个。如果我们将小时数转换为整数并将分钟数保留为字符串，这是一个非常简单的转换
$time = explode(':', $yourdatetime);
$hours = (int)$time[0] . '.' . $time[1];
Avoids any overhead from regex
避免正则表达式的任何开销
