Compare different arrays structures
Question
I have two arrays with different structures. Array 1 and Array 2 that I will name from MyList and MyFiles . I would get to return only MyList values that do not have in MyFiles. But the two arrays have different structures and I'm having trouble trying to compare
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] => 253
[videos] => Array
(
[0] => Array
(
[id] => 2929794
[link] => goals.mp4
)
[1] => Array
(
[id] => 2929793
[link] => best.mp4
)
)
)
)
)
)
MyFiles Array
Array
(
[252] => Array
(
[0] => Array
(
[id] => 2929850
[link] => goals.mp4
)
[1] => Array
(
[id] => 2929848
[link] => best.mp4
)
)
[251] => Array
(
[0] => Array
(
[id] => 2929796
[link] => goals.mp4
)
[1] => Array
(
[id] => 2929795
[link] => best.mp4
)
)
)
the comparison must be made by id of the week and id of the video
I tried this but it did not work out:
$new = array();
foreach ($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;
}
}
}
}
The expected return would be something like this.
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
)
)
)
)
)
)

I have hidden the array in a usable format for my sake in the future should this answer be incorrect and need changing.
$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"; $list["info"][0]["week"]["videos"][0]["id"] = 2929850; $list["info"][0]["week"]["videos"][0]["link"] = "goals.mp4"; $list["info"][0]["week"]["videos"][1]["id"] = 2929848; $list["info"][0]["week"]["videos"][1]["link"] = "best.mp4"; $list["info"][0]["week"]["videos"][2]["id"] = 2929847; $list["info"][0]["week"]["videos"][2]["link"] = "dribbling.mp4"; $list["info"][1]["player"] = "CR7"; $list["info"][1]["week"]["id"] = "251"; $list["info"][1]["week"]["videos"][0]["id"] = 2929796; $list["info"][1]["week"]["videos"][0]["link"] = "goals.mp4"; $list["info"][1]["week"]["videos"][1]["id"] = 2929795; $list["info"][1]["week"]["videos"][1]["link"] = "best.mp4"; $list["info"][2]["player"] = "Neymar"; $list["info"][2]["week"]["id"] = "253"; $list["info"][2]["week"]["videos"][0]["id"] = 2929794; $list["info"][2]["week"]["videos"][0]["link"] = "goals.mp4"; $list["info"][2]["week"]["videos"][1]["id"] = 2929793; $list["info"][2]["week"]["videos"][1]["link"] = "best.mp4"; $file = array(); $file[252][0]['id'] = 2929850; $file[252][0]['link'] = 'goals.mp4'; $file[252][1]['id'] = 2929848; $file[252][1]['link'] = 'best.mp4'; $file[251][0]['id'] = 2929796; $file[251][0]['link'] = 'goals.mp4'; $file[251][1]['id'] = 2929795; $file[251][1]['link'] = 'best.mp4';
Edit
function array_diff_assoc_recursive($array1, $array2) {
$difference=array();
foreach ($array1 as $key => $value) {
if (is_array($value)) {
if( !isset($array2[$key]) || !is_array($array2[$key])) {
$difference[$key] = $value;
} else {
$new_diff = array_diff_assoc_recursive($value, $array2[$key]);
if (!empty($new_diff))
$difference[$key] = $new_diff;
}
} else if (!array_key_exists($key,$array2) || $array2[$key] !== $value) {
$difference[$key] = $value;
}
}
return $difference;
}
$new = array('info' => array());
foreach ($list['info'] as $key => $item) {
$a = $item['week']['videos'];
//$b = $file[$item['week']['id']] ?? []; // This is PHP7+
$b = isset($file[$item['week']['id']]) ? $file[$item['week']['id']] : [];
$c = array_diff_assoc_recursive($a, $b);
if (!empty($c)) {
$new['info'][$key] = $item;
$new['info'][$key]['week']['videos'] = $c;
}
}
You will need a function that will check the difference between the videos arrays.
What I do is simply iterate over the list array and then check the difference between that item and the file array. The difference is then stored in $c .
If there is a difference then if statement is fired which will store that player in the $new array and then replace the videos array with the difference array.
This is similar to what you were doing when you were unsetting variables.
