foreach語句從數組中獲取值

這是我正在使用的一個數組的簡短示例。foreach語句從數組中獲取值

Array ([0] => Array ([Name] => somename [Attributes] => Array ([Body] => somebody 
[Region] => someregion [State] => somestate [Url] => someurl [Date] => somedate [Tz] => 
sometz [Title] => sometitle [City] => somecity)) [1] => Array ([Name] => somename1 
[Attributes] => Array ([Body] => somebody1 [Region] => someregion1 [State] => somestate1 
[Url] => someurl1 [Date] => somedate1 [Tz] => sometz1 [Title] => sometitle1 [City] => 
somecity1)))

我只需要幫助foreach語句來獲取每個數組的值。

基於日期對這些數組進行排序的任何示例都將被讚賞。

感謝

它有助於看看PHP文檔：

http://php.net/manual/en/control-structures.foreach.php

在這種情況下，你只想做：

foreach (your_array_name as $value) 
    //do something with $value

我該網頁上之前，我問的問題，並嘗試了一些例子。只是無法使其工作。 – TDave00 2012-02-26 06:15:05

謝謝，我犯了一個愚蠢的錯誤。我將代碼添加到一個文件中，然後檢查我製作的副本。難怪我無法工作。 'foreach（$ rest as $ value） \t { \t echo $ value ['Name']; \t etc.etc .. \t}' – TDave00 2012-02-26 06:25:14

一種解決方案是使用兩個嵌套foreach()：

foreach ($array as $value) { 
    foreach($value as $v){ 
    echo $v; 
    } 
}

最後，爲了排序數組，您可以使用usort()或cmp()。不要忘了爲您的日期使用相同的格式（最好是ISO 8601），因此您可以輕鬆地對它們進行排序。

使用多種類的技術http://in.php.net/array_multisort

$array1 = array(0 => array('name' => somename1, 'Attributes' => array('Body' => somebody, 
       'Region' => someregion, 'State' => somestate, 'Url' => someurl, 'Date' => '26-02-2011', 'Tz' => 
       sometz, 'Title' => sometitle, 'City' => somecity)), 
     1 => array('name' => somename2, 'Attributes' => array('Body' => somebody, 
       'Region' => someregion, 'State' => somestate, 'Url' => someurl, 'Date' => '25-02-2011', 'Tz' => 
       sometz, 'Title' => sometitle, 'City' => somecity))); 

    foreach ($array1 as $index => $inner_arr) { 
     $attr = $inner_arr['Attributes']; 
     foreach ($attr as $key => $value) { 
      $date_arr[$index] = strtotime($attr['Date']); 
     } 
    } 
//for multisort give date array as the array accoring to which the data to be sorted. 
//We are dumping date into array and trying to sort data according tot he date array sorted. 

    array_multisort($date_arr,$array1); 

    //after sorting loop thru data 
    foreach ($array1 as $inner_arr) { 
     echo "name:". $inner_arr['name']; 
     foreach ($inner_arr['Attributes'] as $key => $value) { 
      echo "<br>$key: $value"; 

     } 
     echo '<hr>'; 
    }
