Flatten multi dimension array but maintain keys? - php

Question

I have the following:
[6199]=>
array(12) {
["Origin"]=>
array(3) {
["name"]=>
array(1) {
[0]=>
string(4) "Cuba"
}
["slug"]=>
array(1) {
[0]=>
string(27) "cuabn-havana-habanos-cigars"
}
["id"]=>
array(1) {
[0]=>
int(0)
}
}
["Filler"]=>
array(3) {
["name"]=>
array(2) {
[0]=>
string(9) "Dominican"
[1]=>
string(10) "Nicaraguan"
}
["slug"]=>
array(2) {
[0]=>
string(9) "dominican"
[1]=>
string(10) "nicaraguan"
}
["id"]=>
array(2) {
[0]=>
int(0)
[1]=>
int(1)
}
}
}
[6192]=>
array(11) {
["Origin"]=>
array(3) {
["name"]=>
array(1) {
[0]=>
string(9) "Nicaragua"
}
["slug"]=>
array(1) {
[0]=>
string(27) "nicaraguan-new-world-cigars"
}
["id"]=>
array(1) {
[0]=>
int(0)
}
}
["Filler"]=>
array(3) {
["name"]=>
array(2) {
[0]=>
string(9) "Java"
[1]=>
string(10) "Nicaraguan"
}
["slug"]=>
array(2) {
[0]=>
string(9) "java"
[1]=>
string(10) "nicaraguan"
}
["id"]=>
array(2) {
[0]=>
int(0)
[1]=>
int(1)
}
}
}
and my expected output is:
array(12) {
["Origin"]=>
array(3) {
["name"]=>
array(1) {
[0]=>
string(4) "Cuba".
[1]=>
string(9) "Nicaragua"
}
["slug"]=>
array(1) {
[0]=>
string(27) "cuabn-havana-habanos-cigars",
[0]=>
string(27) "nicaraguan-new-world-cigars"
}
["id"]=>
array(1) {
[0]=>
int(0)
}
}
["Filler"]=>
array(3) {
["name"]=>
array(2) {
[0]=>
string(9) "Dominican"
[1]=>
string(10) "Nicaraguan"
[2]=>
string(9) "Java"
}
["slug"]=>
array(2) {
[0]=>
string(9) "dominican"
[1]=>
string(10) "nicaraguan"
[3]=>
string(9) "java"
}
["id"]=>
array(2) {
[0]=>
int(0)
[1]=>
int(1)
}
}
See how it eliminates dupes and merges each array maintaining the "origin" key.
I've tried :
foreach ($resultterms as $keyname => $valuename){
foreach ($valuename as $keysub => $valuesub) {
foreach($valuesub['name'] as $keysubsub => $valuesubsub){
# code...
$prods_atts[$keysub]['name'][$keysubsub] = $valuesubsub;
$prods_atts[$keysub]['slug'][$keysubsub] = $valuesub['slug'][$keysubsub];
$prods_atts[$keysub]['id'][$keysubsub] = $valuesub['id'][$keysubsub];
}
}
}
where $resultterms is the original arrays but it's not working. I was wondering if there was a wonderful php function I could use to merge these instead of so many nested for each loops?

Answer 1

I believe you're just looking for array_merge_recursive.
call_user_func_array('array_merge_recursive', array_values($prod_atts));
call_user_func_array allows to transform an array into a list of arguments
array_values because in the end, you seem to want to get rid of the first layer of your array
In order to try it, could you post the var_export of your variable instead of the var_dump?
echo(var_export($prod_atts, true));

Answer 2

merge your array by any suggested method. After that you will get duplicated values. And you need save only the unique items
$new = array_merge_recursive($resultterms['6199'], $resultterms['6192']);
foreach($new['Origin'] as &$item) { $item = array_unique($item); }
foreach($new['Filler'] as &$item) { $item = array_unique($item); }
