Flatten multidimensional array but keep keys?
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:
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 fixes errors and concatenates each array that supports the "origin" key. I 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
are the original arrays, but it doesn't work. I was wondering if there is a great php function I could use to combine them, rather than nesting so many for each loop?

I believe you are just looking for array_merge_recursive .
call_user_func_array('array_merge_recursive', array_values($prod_atts));
-
call_user_func_array
lets you convert an array to a list of arguments -
array_values
because at the end of the day you seem to want to get rid of the first level of your array
To try it out, could you please place var_export
your variable instead var_dump
?
echo(var_export($prod_atts, true));

concatenate the array with any suggested method. After that, you will get duplicate values. And you only need to keep 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); }
