在php中添加两个或更多个时间字符串 [英] add two or more time strings in php

问题描述

我有一个包含时间（字符串）的数组，例如2:23，3：2：22等。

  $ times = array（2:33，4：2：22，3:22）// loner 
  

我想找到所有数组的总和。

有没有办法可以添加像2:33和3:33（i：s）

谢谢

没有内置的方式这样做 - 所有的时间功能都在运行，
不在持续时间。在您的情况下，您可以 explode（）分别添加零件
。我会建议写一个课。简单的例子：

  class Duration {
 
 public static function fromString（$ string）{
 $ parts = explode（'：'，$ string）; 
 $ object = new self（）; 
 if（count（$ parts）=== 2）{
 $ object-> minutes = $ parts [0]; 
 $ object-> seconds = $ parts [1]; 
} elseif（count（$ parts）=== 3）{
 $ object-> hours = $ parts [0]; 
 $ object-> minutes = $ parts [1]; 
 $ object-> seconds = $ parts [2]; 
} else {
 // handle error 
} 
 return $ object; 
} 
 
 private $ hours; 
 private $ minutes; 
 private $ seconds; 
 
 public function getHours（）{
 return $ this-> hours; 
} 
 
 public function getMinutes（）{
 return $ this-> minutes; 
} 
 
 public function getSeconds（）{
 return $ this-> seconds; 
} 
 
 public function add（Duration $ d）{
 $ this-> hours + = $ d-> hours; 
 $ this->分钟+ = $ d->分钟; 
 $ this->秒+ = $ d->秒; 
 while（$ this->秒> = 60）{
 $ this->秒 -  = 60; 
 $ this->分钟++; 
} 
 while（$ this->分钟> = 60）{
 $ this->分钟 -  = 60; 
 $ this->小时++; 
} 
} 
 
 public function __toString（）{
 return implode（'：'，array（$ this-> hours，$ this-> minutes ，$ this->秒））; 
} 
 
} 
 
 $ d1 =持续时间:: fromString（'2:22'）; 
 $ d1-> add（Duration :: fromString（'3:33'））; 
 echo $ d1; // should print 5:55 
  

I have an array with times (string) e.g "2:23", "3:2:22" etc.

$times = array("2:33", "4:2:22", "3:22") //loner

I want to find the total sum of all array.

Is there a way that I could add times like "2:33" and "3:33" ("i:s")

thanks

There is no builtin way of doing this - all time functions operate on times, not on durations. In your case, you can explode() and add the parts separately. I would recommend writing a class. Simple example:

class Duration {

    public static function fromString($string) {
        $parts = explode(':', $string);
        $object = new self();
        if (count($parts) === 2) {
            $object->minutes = $parts[0];
            $object->seconds = $parts[1];
        } elseif (count($parts) === 3) {
            $object->hours = $parts[0];
            $object->minutes = $parts[1];
            $object->seconds = $parts[2];
        } else {
            // handle error
        }
        return $object;
    }

    private $hours;
    private $minutes;
    private $seconds;

    public function getHours() {
        return $this->hours;
    }

    public function getMinutes() {
        return $this->minutes;
    }

    public function getSeconds() {
        return $this->seconds;
    }

    public function add(Duration $d) {
        $this->hours += $d->hours;
        $this->minutes += $d->minutes;
        $this->seconds += $d->seconds;
        while ($this->seconds >= 60) {
            $this->seconds -= 60;
            $this->minutes++;
        }
        while ($this->minutes >= 60) {
            $this->minutes -= 60;
            $this->hours++;
        }
    }

    public function __toString() {
        return implode(':', array($this->hours, $this->minutes, $this->seconds));
    }

}

$d1 = Duration::fromString('2:22');
$d1->add(Duration::fromString('3:33'));
echo $d1; // should print 5:55
