如何按時間順序排列PHP數組與關聯？

Question

我正在爲音樂推廣公司製作網站。對於每一個藝術家，我有一個包含事件信息的一個單獨的陣列，像這樣：

<?php 

$donevents = array(); 
$donevents[101] = array(
    "date" => "March 18th 2013", 
    "artist" => "Don Ross", 
    "venue" => "The Half Moon, Putney", 
    "link" => "http://www.halfmoon.co.uk", 
    "label" => "donross", 
    ); 
$donevents[102] = array(
    "date" => "March 19th 2013", 
    "artist" => "Don Ross", 
    "venue" => "The Moon Club, Cardiff", 
    "link" => "http://www.themoonclub.net/", 
    "label" => "donross", 
    ); 
$donevents[103] = array(
    "date" => "March 21st 2013", 
    "artist" => "Don Ross and Brooke Miller", 
    "venue" => "Round Midnight, London", 
    "link" => "http://www.roundmidnightbar.com", 
    "label" => "donross", 
    ); 
$donevents[104] = array(
    "date" => "March 21st 2013", 
    "artist" => "Don Ross", 
    "venue" => "Masterclass at the Swindon Academy of Music", 
    "link" => "http://www.academyofmusic.ac.uk/locations/location.php?id=9", 
    "label" => "donross", 
    ); 
$donevents[105] = array(
    "date" => "March 23rd 2013", 
    "artist" => "Don Ross", 
    "venue" => "Berits & Brown, Airdrie", 
    "link" => "http://www.intimate-gigs.com", 
    "label" => "donross", 
    ); 
$donevents[106] = array(
    "date" => "March 25th 2013", 
    "artist" => "Don Ross", 
    "venue" => "Masterclass at The Academy of Music, Gateshead", 
    "link" => "http://www.guitarbar.co.uk", 
    "label" => "donross", 
    ); 


?> 

我想所有這些不同的陣列相結合，利用包括，在一個活動頁面，並讓它們按時間順序排列。有沒有辦法做到這一點與「日期」關聯數組？

所以它最終會是這樣的： 2013年3月18日 唐·羅斯 半月，普特尼

二零一三年三月二十日 布魯克·米勒 流浪漢，布里

2013年3月29日 吉米·瓦赫勒斯廷 斯旺西的車庫

Answer 1

是的，你需要使用uasort這樣的功能：

$sortedEvents = $donevents; 
uasort($sortedEvents, function($eventA, $eventB){ 
    $eventDateA = DateTime::createFromFormat('F dS yyyy', $eventA['date']); 
    $eventDateB = DateTime::createFromFormat('F dS yyyy', $eventB['date']); 

    return $eventA->getTimestamp() < $eventB->getTimestamp() ? -1 : 1; 
});
