基于另一个阵列的订单排序阵列子项 [英] Sort Array Subkey Based on Another Array's Order
问题描述
我知道已经有关于数组排序的很多帖子，但我已经看过高低并不能找到一个解决我的问题。
我发现了一个很不错的文章在这里：
http://firsttube.com/read/sorting-a-多维数组与 - PHP /
上面的链接是伟大的，但是，我要采取进一步和排序数组子项基于了另一个数组的顺序。
所以，让我们说我们有五首歌曲的播放列表数组：
阵列
（
[0] =＆GT; 3OH 3 - 不要相信我
[1] =＆GT;泰勒·斯威夫特 - 你是属于我
[2] =＆GT;肖恩金斯顿 - 火燃烧
[3] =＆GT;绿日 - 了解你的敌人
[4] =＆GT;凯利克拉克森 - 飘
）
并让我们说我们有我们想进行排序，以配合我们的播放列表数组的顺序如下信息：
阵列
（
[0] =＆GT;排列
（
[TRACKNAME] =＆GT;泰勒·斯威夫特 - 你是属于我
[trackLength] =＆GT; 0
[trackViews] =＆GT; 0
[trackRating] =＆GT; 0
） [1] =＆GT;排列
（
[TRACKNAME] =＆GT;肖恩金斯顿 - 火燃烧
[trackLength] =＆GT; 0
[trackViews] =＆GT; 0
[trackRating] =＆GT; 0
） [2] =＆GT;排列
（
[TRACKNAME] =＆GT; 3OH！3不要信任我
[trackLength] =＆GT; 205
[trackViews] =＆GT; 4570399
[trackRating] =＆GT; 4.866372
） [3] =＆GT;排列
（
[TRACKNAME] =＆GT; Green Day的了解你的敌人
[trackLength] =＆GT; 191
[trackViews] =＆GT; 4715494
[trackRating] =＆GT; 4.9103785
） [4] =＆GT;排列
（
[TRACKNAME] =＆GT;凯莉·克拉克森：飘
[trackLength] =＆GT; 225
[trackViews] =＆GT; 679019
[trackRating] =＆GT; 4.8995433
））
所以，一次...我的问题是：我如何能获得歌曲阵列由TRACKNAME进行排序，以匹配播放列表阵列相同的顺序
任何帮助或指导，将AP preciated！
感谢。

EDDIE有高手成功的解决方案！道具给他！ 1UP他的答案！ ：）
不过，我稍微修改埃迪的解决方案。我刚才添加的用户输入歌曲名称和歌曲标题之间75％的相似支票抬头的外部来源，因为我无法控制每个标题的细微变化。
$ sorted_list =阵列（）;的foreach（$歌曲$ song_key =＆GT; $歌曲）{
的foreach（$ song_info为$资讯）{
similar_text（$信息['TRACKNAME']，$歌曲，$ P）;
如果（$ P＆GT; 75）{
$ sorted_list [$ song_key] = $信息;
}
}
}
假设你的播放列表是数组$歌曲和你的另一阵列是$ songs_info。
$ sorted_list =阵列（）;的foreach（$歌曲$ song_key =＆GT; $歌曲）{
的foreach（$ song_info为$资讯）{
如果（$信息['TRACKNAME'] == $歌曲）{
$ sorted_list [$ song_key] = $信息;
}
}
}// $ sorted_list包含排序列表
I know there have been many posts regarding array sorting, but I have looked high and low and cannot find a solution to my problem.
I have found a very good article here: http://firsttube.com/read/sorting-a-multi-dimensional-array-with-php/
The above link is great, however, I wish to take it further and sort the array subkey based off the order of another array.
So, let's say we have five songs in the Playlist Array:
Array
(
[0] => 3oh!3 - Don't Trust me
[1] => Taylor Swift - You Belong with me
[2] => Sean Kingston - Fire Burning
[3] => Green Day - Know Your Enemy
[4] => Kelly Clarkson - Gone
)
And let's say we have the following information that we would like sorted to match the order of our Playlist Array:
Array
(
[0] => Array
(
[trackName] => Taylor Swift - You Belong With Me
[trackLength] => 0
[trackViews] => 0
[trackRating] => 0
)
[1] => Array
(
[trackName] => Sean Kingston - Fire Burning
[trackLength] => 0
[trackViews] => 0
[trackRating] => 0
)
[2] => Array
(
[trackName] => 3OH!3- Dont Trust Me
[trackLength] => 205
[trackViews] => 4570399
[trackRating] => 4.866372
)
[3] => Array
(
[trackName] => Green Day Know Your Enemy
[trackLength] => 191
[trackViews] => 4715494
[trackRating] => 4.9103785
)
[4] => Array
(
[trackName] => Kelly Clarkson: Gone
[trackLength] => 225
[trackViews] => 679019
[trackRating] => 4.8995433
)
)
So, again... My question is: How can I get the array of songs to be sorted by the trackName to match the same order of the Playlist Array?
Any help or guidance would be appreciated!
Thanks.
[SOLUTION] EDDIE had the master winning solution! Props to him! 1up his answer! :)
However, I modified eddie's solution slightly. I just added a similarity check of 75% between the user entered song titles and the song titles looked up on the external sources because I cannot control the slight variations of each title.
$sorted_list = array();
foreach($songs as $song_key=>$song){
foreach($song_info as $info){
similar_text($info['trackName'], $song, $p);
if($p > 75){
$sorted_list[$song_key] = $info;
}
}
}
Assuming your playlist is in the array $songs and your other array is in $songs_info.
$sorted_list = array();
foreach($songs as $song_key=>$song){
foreach($song_info as $info){
if($info['trackName'] == $song){
$sorted_list[$song_key] = $info;
}
}
}
// $sorted_list contains sorted list
