我有两个不同结构的数组。我将从MyList和MyFiles命名的数组1和数组2。我只能返回MyFiles中没有的MyList值。但是这两个阵列有不同的结构，我在尝试比较
MYLIST
Array
(
[info] => Array
(
[0] => Array
(
[player] => Messi
[week] => Array
(
[id] => 252
[videos] => Array
(
[0] => Array
(
[id] => 2929850
[link] => goals.mp4
)
[1] => Array
(
[id] => 2929848
[link] => best.mp4
)
[2] => Array
(
[id] => 2929847
[link] => dribbling.mp4
)
)
)
)
[1] => Array
(
[player] => CR7
[week] => Array
(
[id] => 251
[videos] => Array
(
[0] => Array
(
[id] => 2929796
[link] => goals.mp4
)
[1] => Array
(
[id] => 2929795
[link] => best.mp4
)
)
)
)
[2] => Array
(
[player] => Neymar
[week] => Array

[id] => 2929794
[link] => goals.mp4
)
[1] => Array
(
[id] => 2929793
[link] => best.mp4
)
)
)
)
)
)
MyFiles数组

必须通过周的ID和视频的ID来进行比较
我尝试了这个但是没有成功：
$new = array();
foreach ($list['info'] as $source) {
foreach ($source["week"]['videos'] as $keys => $videos) {
foreach ($file as $key => $upload) {
if ($source["week"]["id"] == $key ) {
for($i=0; $i<count($source["week"]["videos"]); $i++){
if($videos["id"] == $upload[$i]["id"]){
unset($videos);
}else{
$new[] = $videos;
}
}
} else {
$new[] = $videos;
}
}
}
}
Array
(
[info] => Array
(
[0] => Array
(
[player] => Messi
[week] => Array
(
[id] => 252
[videos] => Array
(
[2] => Array
(
[id] => 2929847
[link] => dribbling.mp4
)
)
)
)
[2] => Array
(
[player] => Neymar
[week] => Array
(
[id] => 253
[videos] => Array
(
[0] => Array
(
[id] => 2929794
[link] => goals.mp4
)
[1] => Array
(
[id] => 2929793
[link] => best.mp4
)
)
)
)
)
)
答案 0 :(得分：1)
如果这个答案不正确并且需要更改，我已经将数组隐藏在一个可用的格式中，以备将来使用。
$desired = array();
$desired['info'][0]['player'] = 'Messi';
$desired['info'][0]['week']['id'] = 252;
$desired['info'][0]['week']['videos'][2]['id'] = 2929847;
$desired['info'][0]['week']['videos'][2]['link'] = 'dribbling.mp4';
$desired['info'][2]['player'] = 'Neymar';
$desired['info'][2]['week']['id'] = 253;
$desired['info'][2]['week']['videos'][0]['id'] = 2929794;
$desired['info'][2]['week']['videos'][0]['link'] = 'goals.mp4';
$desired['info'][2]['week']['videos'][1]['id'] = 2929793;
$desired['info'][2]['week']['videos'][1]['link'] = 'best.mp4';
$list = array();
$list["info"][0]["player"] = "Messi";
$list["info"][0]["week"]["id"] = "252";

function array_diff_assoc_recursive($array1, $array2) {
$difference=array();

$new = array('info' => array());

您将需要一个能够检查视频阵列之间差异的功能。
我所做的只是迭代列表数组，然后检查该项与文件数组之间的区别。然后将差异存储在$c。
如果存在差异，则触发if语句，将该播放器存储在$new数组中，然后将视频数组替换为差异数组。
这与您在取消设置变量时的操作类似。
