Get only a matched key value from array

Question

I have an array result like this.

Array
(
    [Bank] => Array
        (
            [name] => Bank
            [status] => 1
            [enable_rcb] => 1
        )

    [Cod] => Array
        (
            [name] => Cod
            [status] => 1
            [enable_rcb] => 0
        )

    [Lite] => Array
        (
            [name] => Lite
            [status] => 0
            [enable_rcb] => 0
        )
)

I want to get result from conditional. For example I want show only Bank if the status is 1 and leave the rest array. I try to show them like this

        $results = array();
        foreach ($user_pay as $value) {
            foreach ($value as $k => $v) {
                if($value['status']=="1"){
                    $user_payment[] = $value['name'];
                }
            }
            $results = $user_payment;
        }

But the result give me duplicate result like this

Array
(
    [0] => Bank
    [1] => Bank
    [2] => Bank
    [3] => Bank
    [4] => Bank
    [5] => Bank
    [6] => Cod
    [7] => Cod
    [8] => Cod
    [9] => Cod
    [10] => Cod
)

What I want is to get the name of an array which is have status 1 and it should be like this

Array
(
    [0] => Bank
    [1] => Cod
)

How to avoid this duplicate result?

Does this answer your question? [How to search by key=>value in a multidimensional array in PHP](https://stackoverflow.com/questions/1019076/how-to-search-by-key-value-in-a-multidimensional-array-in-php) — BhAvik Gajjar, Dec 11 '19 at 06:57
After editing my answer below, I realized something weird: how come you can have duplicates if the names are also your array's keys? You can't have the same twice. — Jeto, Dec 11 '19 at 07:23
Your inner loop can just be removed `foreach ($value as $k => $v) {` - you don't even use the values from this loop! — Nigel Ren, Dec 11 '19 at 07:56

You may use array_filter to retrieve only the ones with the desired status, then array_column to grab their names:

$filtered = array_filter($arr, static function ($entry) {
  return $entry['status'] === 1;
});

$names = array_column($filtered, 'name');

thanks for help, but this result as null value and give me a blank page – GregoriRasputin Dec 11 '19 at 08:42
@GregoriRasputin As you can check in the provided link, this works fine unless you're on PHP 5.5.0 or below (in which case, I highly recommend you upgrade). – Jeto Dec 11 '19 at 08:50
yes, I'm on php 5 right now, Upgrade means change all code in my file? – GregoriRasputin Dec 11 '19 at 09:00
@GregoriRasputin No I mean upgrading to PHP7. This can take a bit of time depending on your codebase, but you'll get way better performance, stability, and features. PHP5 isn't even supported anymore. (And if you absolutely can't, at the very least upgrade to PHP5.6, this answer will work fine with it.) – Jeto Dec 11 '19 at 09:10
Thanks. You give me best suggestion. I will update it later. – GregoriRasputin Dec 11 '19 at 11:02

You can change loop such that

$results = array();
foreach($array as $key=>$value):
    if($value["status"]){
      $results[] = $value["name"];
    }
endforeach;

You can approach it like

$new = array_keys(array_filter($a,function($v){
  return $v['status'] > 0;
}));

print_r($new);

can I do with multiple condition? Like if status 1 and enable_rcb 1 then show the name – GregoriRasputin Dec 11 '19 at 07:11
@GregoriRasputin Yes you can, just put like this `$v['status'] > 0 && $v['enable_rcb'] ==1` – Rakesh Jakhar Dec 11 '19 at 07:12

You can use array_unique()

$result = array_unique($result);
