string(3) "xyz"
["contact"] =>
string(5) "12345"
["address"] =>
string(3) "xyz"
["seller_id"] =>
string(1) => "1"
}
[0]=>
array(5) {

Answer 1

Use the array_filter php function.

$filtered = array_filter(
    $arrItems['items'],
    function ($item) {
        return isset($item['seller_id']) && $item['seller_id'] == 1;
    }
);

Answer 2

Fortunatly am giving answer of my own question

$arr = [];
foreach ($arrItems['items'] as $i => $row) {
    if ($row['seller_id'] != 1) {
        // Ignore row if seller_id is not 1
        continue;
    }

    // here you got only elements with seller_id = 1
    // so you can add them to a new array
    $arr[] = $row;
}

// After the loop (foreach) in $row you get only elements with seller_id 1.
// If they must be in $arrItems['items'] use it
$arrItems['items'] = $arr;

echo '<pre>';
print_r($arrItems['items']);
echo '</pre>';

The Output is :

Array
(
    [f_name] => abc
    [l_name] => xyz
    [contact] => 12345
    [address] => xyz
    [seller_id] => 1
)
Array
(
    [f_name] => abc
    [l_name] => xyz
    [contact] => 12345
    [address] => xyz
    [seller_id] => 1
)
Array
(
    [f_name] => abc
    [l_name] => xyz
    [contact] => 12345
    [address] => xyz
    [seller_id] => 1
)
