I have an array that has some keys that are repeating multiple times. Would like to combine them so that I can have them in one array, within the same array. I have an array of this type;
Array
(
[Shoes] => Array
(
[POLO] => Array
(
[0] => Size5
)
)
)
Array
(
[Shoes] => Array
(
[FUBU] => Array
(
[0] => size6
)
)
)
Array
(
[Bag] => Array
(
[HPBAG] => Array
(
[0] => Black
)
)
)
Array
(
[Bag] => Array
(
[HPBAG] => Array
(
[0] => White
)
)
)
I would like an output of the following kind;
Array
(
[Shoes] => Array
(
[POLO] => Array
(
[0] => size5
)
[FUBU] => Array
(
[0] => size6
)
)
[Bag] => Array
(
[HPBAG] => Array
(
[0] => Black
[1] => White
)
)
)
I have tried array_merge, array_merge_recursive but all are not working.
foreach ($county as $value) { print_r(array_merge($value)); } //$value contains the array
foreach ($county as $value) { print_r(array_merge_recursive($value)); } //$value contains the array
Kindly assist if you have an idea on how to solve this in PHP.
You could do it with a few nested array_walk()
calls:
$arr=array(array("Shoes" => array("POLO" => array("Size5"))),
array("Shoes" => array("FUBU" => array("size6"))),
array("Bag" => array("HPBAG" => array("Black"))),
array("Bag" => array("HPBAG" => array("White"))));
$res=[];
array_walk($arr,function($a) use (&$res){
array_walk($a, function($ar,$type) use (&$res){
array_walk($ar, function ($arr,$brand) use (&$res,$type){
$res[$type][$brand]=array_merge($res[$type][$brand]??[],$arr);
});
});
});
print_r($res);
See the demo here: https://rextester.com/RFLQ18142
It produces this result:
Array
(
[Shoes] => Array
(
[POLO] => Array
(
[0] => Size5
)
[FUBU] => Array
(
[0] => size6
)
)
[Bag] => Array
(
[HPBAG] => Array
(
[0] => Black
[1] => White
)
)
)
