You can use array_map to apply array_sum to each of the elements of the array:
$sum_array = array_map(function ($v) { return array_sum($v); }, $array);
print_r($sum_array);
Demo on 3v4l.org


You can use the code below. Good luck!
$data=[
1001 => [ 500],1024 => [750],1202 =>[0,10000,138456],1203=>[300]
];
foreach($data as $key => $value){
if(count($data[$key]) > 1){
$data[$key]=array_sum($data[$key]);
}else{
$data[$key] =$data[$key];
}
}

you can use two foreach loop inside each other and array_search() like this:
$a = array("L1" => [ 0 => "TL422632" ],"L2"=> [ 0 => "TL422635" ]);
$x = "TL422635";
foreach($a as $key=>$value){
if($x === $value){
return $key;
}else{
foreach($value as $k=>$v){
if($x === $v){
return array_search([$k=>$v],$a);
}
}
}
}

PHP array sort by number of items

I need to sort my array-based on the number of elements in the inner array.
It's my current array.
Array
(
[0] => Array
(
)
[1] => Array
(
[0] => 2-3
)
[2] => Array
(
[0] => 5-9
)
[3] => Array
(
[0] => 5-9
[1] => 2-3
)
)
I need to sort the array by this format.
Array
(
[3] => Array
(
[0] => 5-9
[1] => 2-3
)
[2] => Array
(
[0] => 5-9
)
[1] => Array
(
[0] => 2-3
)
[0] => Array
(
)
)

This seems to do it:
<?php
$a = [
[], ['2-3'], ['5-9'], ['5-9', '2-3']
];
$f = fn ($b, $c) => count($c) <=> count($b);
usort($a, $f);
print_r($a);
https://php.net/function.usort

i hope this answer help you
$result = array();
$sorter = array();
foreach($values as $key => $vals){
$sorter[$key]= count($vals);
}
arsort($sorter);
foreach ($sorter as $ii => $va) {
$result[$ii]=$values[$ii];
}
output

Combine/Merge arrays that have the same keys PHP

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
)
)
)

How can i rearrange a php array without using key names

My array is below i need to arrange like array2 (without use $aa['caption1'] like names directly)
arrray1 is
Array
(
[0] => Array
(
[caption1] => Array
(
[0] => gfdhgfjhg
[1] => dfhfgjghk
)
[caption2] => Array
(
[0] => shgjgh
[1] => dhfgkgjl
)
[banner_image] => Array
(
[0] => assets/images/page_content/img_namT7.jpg
[1] => assets/images/page_content/img_R8mzP.jpg
)

arrray2 is(Required format )
Array
(
[0] => Array
(
array('caption1'=>'caption1','caption2'=>'shgjgh','banner_image'=>'assets/images/page_content/img_namT7.jpg'),
array('caption1'=>'dfhfgjghk','caption2'=>'dhfgkgjl','banner_image'=>'page_content/img_R8mzP.jpg')
)
[1] => Array
(
array('heading'=>'','pragraph'=>''),
array('heading'=>'fgh','pragraph'=>'ghgh'),
)
)
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
(
[0] => Array
(
[heading] =>
[pragraph] =>
)
)

Delete a dimension in a array

Is there a way to delete a dimension in a array (only if it's empty), it's pretty dificult to explain with words, so that's what i want to do :
I have an array that returns :
(
[region1] => Array
(
[] => Array
(
[0] => citie1
[1] => citie2
)
[region2] => Array
(
[] => Array
(
[0] => citie1
[1] => citie2
[2] => citie3
)
)
)
I want it to be :
(
[region1] => Array
(
[0] => citie1
[1] => citie2
)
[region2] => Array
(
[0] => citie1
[1] => citie2
[2] => citie3
)
)

foreach($array as $key => $value) {
$array[$key] = reset($value);
}
That will replace each value in the outer array with the first element of that value.
