Check any one match in array php - php

Question

I have array like below.
(
[TestData1] => Array
(
[0] => Array
(
[SKU] => A01
[SKUType] => Test
[State] => Yes
)
[1] => Array
(
[SKU] => A02
[SKUType] => Test
[State] => Yes
)
[2] => Array
(
[SKU] => A01
[SKUType] => Test
[State] => Yes
)
[3] => Array
(
[SKU] => A03
[SKUType] => Test
[State] => Yes
)
)
[TestData2] => Array
(
)
[TestData3] => Array
(
)
)
I need to check if the given SKU is exist or not in the TestData1 array.
If exist need to check the State value that should be Yes.
Example given sku is
$skutotest = 'A01';
How to find if the value present in the above array using PHP.
Right now i tried like below.
$Details = result_array; // here reading array data from api
$parent_sku = A01;
$Results = $Details['$TestData1'];
foreach($Results as $res){
$sku= $res['SKU'];
$state = $res['State'];
if($sku== $parent_sku && $state == "Yes"){
return true;
break;
}else{
return false;
}
}
Once i found the match, need to stop executing and return true, is the above code correct?
Can anyone help me with this. Thanks

Answer 1

Check this one liner,
$exists = false;
$key = "TestData1";
$skutotest = "A01";
if (array_key_exists($key, $arr)) { // for check if key exists
return ($arr[$key][array_search($skutotest, array_column($arr[$key], 'SKU'))]['State'] == 'Yes');
}
array_search — Searches the array for a given value and returns the first corresponding key if successful
array_column — Return the values from a single column in the input array
Demo.
EDIT
Proper solution for your problem,
$exists = false;
$key = "TestData1";
$val = "A01";
if (array_key_exists($key, $arr)) {
array_walk($arr[$key], function ($item) use ($val, &$exists) {
if ($item['SKU'] == $val && $item['State'] == 'Yes') {
$exists = true;
return;
}
});
}
return ($exists);

Following function has been used in the solution :
array_combine() - Creates an array by using one array for keys and another for its values
array_column() - Return the values from a single column in the input array
array_key_exists() - Checks if the given key or index exists in the array
$skuToSearch = 'A01';
$parentKey = 'TestData1';
$res = array_combine(
array_column($arr[$parentKey] , 'SKU'),
array_column($arr[$parentKey] , 'State')
);
$found = (array_key_exists($skuToSearch, $res) && $res[$skuToSearch] == 'Yes') ? true : false;
Explanation:
variable $skuToSearch, put the SKU which you want to search.
variable $parentKey hold the key of the parent subarray.
array_column($arr[$parentKey] , 'SKU') will return an array with SKU's
array_column($arr[$parentKey] , 'State') will return an array with States
Variable $found will return true OR false, if the SKU found and have state values Yes
