Question

我有这个数组

$test = $_POST['test'];

print_r($test); 

Array
(
    [0] => Array
        (
            [id] => 26629
            [timestamp] => 1332273712
        )

    [1] => Array
        (
            [id] => 26628
            [timestamp] => 1332243526
        )

    [2] => Array
        (
            [id] => 26627
            [timestamp] => 1332237777


)

我希望获得时间戳值并使用函数将其更改为5秒前，4小时前等等。该功能很简单，我只是使用time（） - timestamp ..

然后，当我得到新值时，必须使用它们创建一个新的数组，这些数组将会包含类似的内容

Array
(
    [0] => Array
        (
            [id] => 26629
            [content] => 5 sec ago
        )

    [1] => Array
        (
            [id] => 26628
            [content] => 4 hours ago
        )

    [2] => Array
        (
            [id] => 26627
            [content] => 1 hour ago


)

可能我必须使用foreach但我不知道如何:(

Answer 1

您可以使用array_walk_recursive().

你可能看起来像这样：

//Make a copy of the array first, then operate on it, so that the final result is a seperate array.
$final = $test;

function transformTime(&$item, $key){

    if($key == "timestamp"){
        //Do something to $item
    }
}

array_walk_recursive($final, 'transformTime');

//Convert to JSON for XHR:
$result = json_encode($final);

我正在测试的代码：

<?php

$test = array(

        array('id' => 26629, 
        'timestamp' => 1332273712),

        array('id' => 26628, 
        'timestamp' => 1332243526),

        array('id' => 26629,
        'timestamp' => 1332273712),

        array('id' => 26629,
        'timestamp' => 1332273712),
);

var_dump($test);

$final = $test;

function transformTime(&$item, $key){

    if($key == "timestamp"){
        $item = $item + 5; //Obviously you need to convert the timestamp to something friendly here.
    }
}

array_walk_recursive($final, 'transformTime');

var_dump($final);

Answer 2

foreach ($test as $key => $value) {
    $test[$key]['content'] = get_timeago($value['timestamp']);
}

从Here复制get_timeago功能。

Handling array

$arr = array
(
    0 => array
        (
            'id' => 26629,
            'content' => '5 sec ago',
        ),

    1 => array
        (
            'id' => 26628,
            'content' => '4 hours ago',
        ),

    2 => array
        (
            'id' => 26627,
            'content' => '1 hour ago',
        )

);

 foreach($arr as $arr1)
 {
    foreach($arr1 as $key=>$val)
    {
        echo $val.'<br />';
    }

}

 Find ago time pass time to it

function agoWord( $value )
  {
    if(isset ($value))
    {

      if(time() < strtotime($value))
      {
        $agoWord = "away";
      }
      else
      {
        $agoWord = "ago";
      }
      return $agoWord;
    }
    else
    {
      return 'Time not set for display.';
    }
  }

Function to calculate time differnce

function timeDiff($value)
  {
    if(isset ($value))
    {
      $ago = abs(time() - strtotime($value));

      if($ago < 60)
      {
          $span = $ago;
          return ($span != 1) ? $span." seconds" : " a second";
      }
      if($ago < 3600)
      {
          $span = round($ago/60);
          return ($span != 1) ? $span." minute" : " one minute";
      }
      if($ago < 86400)
      {
          $span = round($ago/3600);
          return ($span != 1) ? $span." hours" : " one hours";
      }

      if($ago < 2592000) // 86400*30 (Month)
      {
          $span = round($ago/86400);
          return ($span != 1) ? $span." days" : " one day";
      }

      if($ago < 31536000) // 86400*365 (time<Year)
      {
          $span = round($ago/2592000);
          return ($span != 1) ? $span." months" : " one month";
      }

      if($ago >= 31536000) //86400*365 (time>=Year)
      {
          $span = round($ago/31536000);
          return ($span != 1) ? $span." years" : " one year";
      }
    }
    else
    {
      return 'error';
    }
  }

如何在此之后拆分数组以更新它并创建一个新数组
