Convert order of array of array in php - php

I am trying to change the order of php array of array.
$arrKeysWithoutValues = array("id", "mobile", "stockCode");
$new_data = array();
foreach ($arrKeysWithoutValues as $key) {
//$list is array of array
$new_data[$key] = array_column($list, $key);
}
//what I received is as follows
//Array ( [id] => Array ( [0] => 4967 [1] => 4965 ) [mobile] => Array ( [0] => ****0030008 [1] => ****0030009 ) [stockCode] => Array ( [0] => sh600036 [1] => sh600036 ) )
//what I need is as follows
//Array ( [0] => Array ( [id] => 4967 [mobile] => ****0030008 [stockCode] => sh600036 ) [1] => Array ( [id] => 4965 [mobile] => ****0030009 [stockCode] => sh600036 ) )
What I received and what I needed is as in above comments. How can I solve this?
Sample structure of the list is as follows.
Array ( [0] => Array ( [id] => 4967 [stockCode] => sh600036 [mobile] => ****0030008 ) [1] => Array ( [id] => 4965 [stockCode] => sh600036 [mobile] => ****0030009 ) )

Don't touch and push the keys.
$new_data[$key] = array_column($list, $key);
// ^ this will yield different results
You use the order array and flip them into keys, then array_merge it with the original list, so then you keep the desired order. Like so:
$new_data = array();
$keys = array_flip($arrKeysWithoutValues); // flip and turn it to keys
foreach ($list as $l) {
$new_data[] = array_merge($keys, $l);
// ^^ merge them
}

Sequence issue with nested foreach loop php

I have two array. array one and array two. I want to merge these array into single array with key. My output result is valid but sequence is not correct.
Array one
Array
(
[0] => test-685f1e7bc357187e449479d627100102
[1] => test-685f1e7bc357187e449479d627d29390
)
Array two
Array
(
[0] => DF955298-A664-4FA7-9586-FCD4CF977777
[1] => DF955298-A664-4FA7-9586-FCD4CF988888
)
Expected Result
Array
(
[0] => Array
(
[key] => test-685f1e7bc357187e449479d627100102
[uuid] => DF955298-A664-4FA7-9586-FCD4CF977777
)
[1] => Array
(
[key] => test-685f1e7bc357187e449479d627d29390
[uuid] => DF955298-A664-4FA7-9586-FCD4CF988888
)
)
My code is for that result is mentioned below:
$record = array();
foreach ($keys_array as $key => $all_key) {
foreach ($uuid_array as $uuid_key => $all_uuid) {
$record[$key]['key'] = $all_key;
$record[$uuid_key]['uuid'] = $all_uuid;
}
}
My output sequence is not valid. Where is the problem
Array
(
[0] => Array
(
[key] => test-685f1e7bc357187e449479d627100102
[uuid] => DF955298-A664-4FA7-9586-FCD4CF977777
)
[1] => Array
(
[uuid] => test-685f1e7bc357187e449479d627d29390
[key] => DF955298-A664-4FA7-9586-FCD4CF988888
)
)
Simple solution:
$record = array();
foreach ($keys_array as $key => $all_key) {
$record[] = [
'key' => $all_key,
// get value under the same key from `$uuid_array`
'uuid' => $uuid_array[$key],
];
}

)
)
please any one help me.
The solution using array_keys, array_map and array_combine functions:
// $arr is your initial array
$result = [];
foreach($arr as $v){
$keys = array_keys($v);
$data = call_user_func_array('array_map', [null] + $v);
$result[] = array_map(function($item) use($keys){
return array_combine($keys, $item);
}, $data);
}
print_r($result);
The output:
Array
(
[0] => Array
(
[0] => Array
(
[caption1] => gfdhgfjhg
[caption2] => shgjgh
[banner_image] => assets/images/page_content/img_namT7.jpg
)
[1] => Array
(
[caption1] => dfhfgjghk
[caption2] => dhfgkgjl
[banner_image] => assets/images/page_content/img_R8mzP.jpg
)
)
[1] => Array

Change key of multidimensional array

I have following array as response from db. I am trying to convert this database response into multidimensional array as per my requirement.
Array
(
[0] => Array
(
[0] => Array
(
[_id] => C10359
[AE] => Array
(
[0] => 89785
[1] => 89786
[2] => 89857
[3] => 89859
)
)
[1] => Array
(
[_id] => C10428
[AE] => Array
(
[0] => 50191
[1] => 50203
[2] => 50230
[3] => 50244
)
)
)
[1] => Array
(
[0] => Array
(
[_id] => C10350
[AE] => Array
(
[0] => 89785
[1] => 89786
[2] => 89857
[3] => 89859
)
)
[1] => Array
(
[_id] => C10430
[AE] => Array
(
[0] => 50191
[1] => 50203
[2] => 50230
[3] => 50244
)
)
)
)
Now I need to convert above array in following way.
Array
(
[0] => Array
(
[C10359] => Array
(
[0] => 89785
[1] => 89786
[2] => 89857
[3] => 89859
)
[C10428] => Array
(
[0] => 50191
[1] => 50203
[2] => 50230
[3] => 50244
)
)
[1] => Array
(
[C10350] => Array
(
[0] => 89785
[1] => 89786
[2] => 89857
[3] => 89859
)
[C10430] => Array
(
[0] => 50191
[1] => 50203
[2] => 50230
[3] => 50244
)
)
)
following is way i am trying
array_map(function($arr) {
return $arr[0] ;
},$panel_result);
But it is not working.
Kindly suggest how can I convert in required formate.
This should do the trick :
$arr = array(
array(
array(
'_id' => 'C10359',
'AE' => array
(
89785,
89786,
89857,
89859,
),
),
array(
'_id' => 'C10428',
'AE' => array
(
50191,
50203,
50230,
50244,
),
),
),
);
$output = array();
foreach ($arr as $levelK => $level) {
if(!isset($output[$levelK])){
$output[$levelK] = array();
}
foreach ($level as $subLevel) {
$id = $subLevel['_id'];
if (!isset($output[$levelK][$id])) {
$output[$levelK][$id] = array();
}
foreach ($subLevel['AE'] as $val) {
$output[$levelK][$id][] = $val;
}
}
}
Hope this helps.
Use array_column() and pass third param as the index key.
$reqArray = array();
foreach ($yourArray as $key => $innerArray) {
$reqArray[] = array_column($innerArray, 'AE', '_id');
}
OR
Use array map()
$reqArray = array_map(function($a){
return array_column($a, 'AE', '_id');
},$arr);

PHP Multidimensional sort?

I have a rather annoying array structure to work with and I need to sort it by any arbitrary key combination. 2 records are displayed below but multiple records with or without the same structure will be present when sorting is actioned.
Here are two records.
Array(
[0] => Array
(
[cid] => 1
[title] => Mr
[first_name] => Abet
[last_name] => Simbad
[emails] => Array
(
[374] => Array
(
[eid] => 374
[name] => ski lodge
[email] => simbad#skifree.com
)
[373] => Array
(
[eid] => 373
[name] => work
[email] => simbad#work.com
)
[375] => Array
(
[eid] => 375
[name] => personal
[email] => simbad#gmail.com
)
)
)
[1] => Array
(
[cid] => 2
[title] => Mrs
[first_name] => Angie
[last_name] => Stokes
[emails] => Array
(
[590] => Array
(
[eid] => 590
[name] => work
[email] => angie#gmail.com
)
)
)
So if I wanted to sort by email in ascending order in the emails array, how can I get the second complete record to come first in the result array? angie#gmail.com comes before simbad#....
Also Some records will not contain an emails array. They would be last in the result set.
Any help would be much appreciated.
The array shown is a cut down version but I have addresses, notes, phones and websites in the same annoying structure. Ideally I could sort with something like
$sort = array('emails','email')
$data = sort_data_func('ASC',$sort,$data);
But anything steps in the right direction will help. :)
Here's some code I have so far
$sort = array('emails','email');
foreach($contacts as $ckey => $c){
if(is_array($c[$sort[0]])){
foreach($c[$sort[0]] as $key1 => $sort0){
if($sort0[$sort[1]]!=''){
$res[$sort[0]][$ckey][$sort[1]][] = $sort0[$sort[1]];
}
}
}
}
print_r($res);
Which produces:
Array
(
[emails] => Array
(
[0] => Array
(
[0] => simbad#skifree.com
[1] => simbad#work.com
[2] => simbad#gmail.com
)
[1] => Array
(
[0] => angie#gmail.com
)
)
)
But I have no idea where to go from here.
EDIT
OK I have the records in the currect order now but how can I keep the initial record ID in the resulting array?
Here's what I'm using.
$direction=='ASC'
function cmp_asc($a, $b){
$key = current(array_keys($a));
sort($a[$key]);
$a[$key] = current($a[$key]);
sort($b[$key]);
$b[$key] = current($b[$key]);
if ($a == $b) {
return 0;
}
return ($a < $b) ? -1 : 1;
}
function cmp_desc($a, $b){
$key = current(array_keys($a));
asort($a[$key]);
$a[$key] = current($a[$key]);
asort($b[$key]);
$b[$key] = current($b[$key]);
if ($a == $b) {
return 0;
}
return ($a < $b) ? -1 : 1;
}
if($direction=='ASC'){
usort($res[$sort[0]], 'cmp_asc');
}else{
usort($res[$sort[0]], 'cmp_desc');
}
In
Array
(
[emails] => Array
(
[0] => Array
(
[email] => Array
(
[0] => simbad#skifree.com
[1] => simbad#work.com
[2] => simbad#gmail.com
)
)
[1] => Array
(
[email] => Array
(
[0] => angie#gmail.com
)
)
)
)
Out
Array
(
[emails] => Array
(
[0] => Array
(
[email] => Array
(
[0] => angie#gmnail.com
)
)
[1] => Array
(
[email] => Array
(
[0] => simbad#skifree.com
[1] => simbad#work.com
[2] => simbad#gmail.com
)
)
)
)
One of the usort functions, combined with a self-written comparison function that detects the order in which two elements should be sorted, should do the trick.

How can I flip an array when each value is also an array?

How would I go about flipping an array and establishing relationships between all the values and keys? For example:
I am trying to turn this:
Array (
[11913] => Array (
[0] => 4242
[1] => 3981
)
[9878] => Array (
[0] => 2901
[1] => 3981
)
[11506] => Array (
[0] => 3981
[1] => 2901
)
)
Into this:
Array (
[3981] => Array (
[0] => 11506
[1] => 9878
[2] => 11913
)
[2901] => Array (
[0] => 11506
[1] => 9878
)
[4242] => Array (
[0] => 11913
)
)
Are there any PHP functions that will already do this automatically? If not what would be a way of going about this? Can't seem to wrap my head around it.
Here you go.
$final_array = array();
foreach($initial_array as $key => $val){
foreach($val as $v){
$final_array[$v][] = $key;
}
}
