Question

我正在试图弄清楚如何将一组持续时间（视频长度）加在一起以获得整个系列的最终长度。

值将采用H:i:s格式：

$durations = array(
   '00:05:34',
   '00:03:26',
   '00:06:13',
   '00:05:15'
);

有没有简单的方法来获得这种数组值的总时间？

Answer 1

快速而肮脏的实施;

function AddTime(Array $durations) 
{
    $total_time    = 0;
    foreach($durations as $duration) {  
        sscanf($duration, "%d:%d:%d", $hours, $minutes, $seconds);
        $total_time += isset($seconds) ? $hours * 3600 + $minutes * 60 + $seconds : $hours * 60 + $minutes;
    }    
    return sprintf('%02d:%02d:%02d', ($total_time/3600),($total_time/60%60), $total_time%60);;
 }

$durations     = array(
   '00:05:34',
   '00:03:26',
   '00:06:13',
   '00:05:15'
);

echo AddTime($durations);

这里我开发了持续时间计算功能。只需复制并通过它。

<?php
function duration_cal($durations)
{
   $sec = 0;
   foreach($durations as $du)
   {
        $timarr = explode(":",$du);
        $hh = $timarr[0];
        $mm = $timarr[1];
        $ss = $timarr[2];

        $sec = $sec + ($hh*60*60) + ($mm * 60) + $ss;
   }

   $hh = floor($sec/3600);
   $mm = floor(($sec%3600) / 60);
   $ss = (($sec%3600) % 60);

   $hh = str_pad($hh, 2, '0', STR_PAD_LEFT);
   $mm = str_pad($mm, 2, '0', STR_PAD_LEFT);
   $ss = str_pad($ss, 2, '0', STR_PAD_LEFT);

   return $hh.":".$mm.":".$ss;
}


$durations = array(
   '00:05:34',
   '00:03:26',
   '00:06:13',
   '00:05:15'
);

echo duration_cal($durations);
?>

与Date/Time：

的乐趣

$durations = array(
    '00:05:34',
    '00:03:26',
    '00:06:13',
    '00:05:15'
);

$startDate = new DateTime('2000-01-01', new DateTimeZone('America/Los_Angeles'));
$endDate   = new DateTime('2000-01-01', new DateTimeZone('America/Los_Angeles'));

foreach ($durations as $duration) {
    list($H, $i, $s) = explode(':', $duration);
    $endDate->add(new DateInterval(sprintf('PT%sH%sM%sS', $H, $i, $s)));
}

echo $startDate->diff($endDate)->format('%H:%I:%S');

吐出：00:20:28

从来源找到并获取/借用：

<?php 

class times_counter {

    private $hou = 0;
    private $min = 0;
    private $sec = 0;
    private $totaltime = '00:00:00';

    public function __construct($times){

        if(is_array($times)){

            $length = sizeof($times);

            for($x=0; $x <= $length; $x++){
                    $split = explode(":", @$times[$x]); 
                    $this->hou += @$split[0];
                    $this->min += @$split[1];
                    $this->sec += @$split[2];
            }

            $seconds = $this->sec % 60;
            $minutes = $this->sec / 60;
            $minutes = (integer)$minutes;
            $minutes += $this->min;
            $hours = $minutes / 60;
            $minutes = $minutes % 60;
            $hours = (integer)$hours;
            $hours += $this->hou % 24;
            $this->totaltime = $hours.":".$minutes.":".$seconds;
        }
    }

    public function get_total_time(){
        return $this->totaltime;
    }

}

// Your array
$times = array(
   '00:05:34',
   '00:03:26',
   '00:06:13',
   '00:05:15'
);

$counter = new times_counter($times);
echo $counter->get_total_time();

//outputs:
// 0:20:28

我相信它是与你试图实现的逻辑分离的任务并将其包装为辅助（或转换器）类，代码是自我解释的：

class Helper_TimeAggregator {

    private $_durations = null;
    private $_seconds = null;

    /**
     * Constructor with init & constructor by default
     */
    public function __construct($durations = null) {
        if (isset($durations)) {
            $this->setDurations($durations);
        }
    }

    /**
     *  Setter for init
     */
    public function setDurations($newDurations) {
        $this->_durations = $newDurations;
        $this->_seconds = null;
    }

    /**
     *  Returns total seconds
     */
    public function getTotalSeconds() {
        if (!isset($this->_seconds)) {
            if (!is_array($this->_durations)) {
                return '00:00:00';
            }
            $seconds = 0;
            foreach ($this->_durations as $duration) {
                $parts = explode(':', $duration);
                if (3 === count($parts)) {
                    $seconds += $parts[0] * 3600;
                    $seconds += $parts[1] * 60;
                    $seconds += $parts[2];
                }
            }
            $this->_seconds = $seconds;
        }
        return $this->_seconds;
    }

    /**
     *  Converts to data
     */
    public function getTotalTime() {
        return date("H:i:s", $this->getTotalSeconds());
    }

    /**
     *  Using default method by default
     */
    public function __toString() {
        return $this->getTotalTime();
    }
}

使用示例：

$durations = array(
   '00:05:34',
   '00:03:26',
   '00:06:13',
   '00:05:15'
);
$t = new Helper_TimeAggregator($durations);
echo $t;

欢迎所有改进！
