@www888 That's what you can try-
$items =
[
[],
[
1,
'',
'42U7036319',
'234BKG03273240',
],
[
2,
'',
'442MSKU4602383',
'218739996'
],
[
3,
'',
'223MSKU4636845',
'21428739996'
]
];
$positionInStr = array_search('442MSKU4602383', Arr::dot($items));
// Here is array keys
$arrayKeys = Str::of($positionInStr)->explode('.');
dd(
$items[$arrayKeys[0]][$arrayKeys[1]]
);

@tisuchi This returns 442MSKU4602383 and not key number

@www888 you tried the very first answer and it didn't work?
Edit
This code taken from https://stackoverflow.com/questions/1019076/how-to-search-by-key-value-in-a-multidimensional-array-in-php
Does work, I just tested.
function _search_array_by_value($array, $value) {
$results = array();
if (is_array($array)) {
$found = array_search($value,$array);
if ($found) {
$results[] = $found;
}
foreach ($array as $subarray)
$results = array_merge($results, $this->_search_array_by_value($subarray, $value));
}
return $results;
}
It would be easier on you if you had "named" or string keys to work with.
Above gives answer in an array however:
^ array:1 [▼
0 => 2
]
The value in answer is the key to the search: '442MSKU4602383'
Just FYI, sometimes try a Google first, I and others here also search when we need things like array help.
Edit
I think you want which sub array it's located, so:
$search = '442MSKU4602383';
$subarray = false;
foreach ($items as $k => $v)
if (in_array($search, $v)) {
$subarray = $k;
break;
}
dd($subarray);
Give you 2 which is this:
[
2,
'',
'442MSKU4602383',
'218739996'
],

@www888 You should use $arrayKeys that will give you found keys.
Have you tried it?

Hello @www888 this work for me.
$a = Array(
Array
(
'color' => "Red",
'age' => 22,
),
Array
(
'color' => "Blue",
'age' => 44,
),
);
$thekey = array_search('Red', array_column($a, 'color'));;
dd($thekey);

$foo = [
0 => [],
1 => [
2 => '42U7036319',
3 => '234BKG03273240'
],
2 => [
10 => '218739996'
]
];
function search($haystack, $needle) {
foreach($haystack as $key => $value ) {
if (is_array($value) && $result = search($value, $needle)) {
return $result;
}
if ($value === $needle) {
return $key;
}
}
return false;
}
var_dump(search($foo, '234BKG03273240')); // 3
var_dump(search($foo, '218739996')); // 10
