How to check a value on multidimensional array PHP

Question

I'm trying to check value on my cart in my codeigniter project, i have this array:

$cart = Array
(
    [547650d3bfb9bce7ea6d61faf312fa41] => Array
        (
            [id] => 1502369193000
            [productid] => Product 1
            [qty] => 1
            [type] => sales
            [user_id] => admin
            [rowid] => 547650d3bfb9bce7ea6d61faf312fa41
        )

    [7473a2e4d2e4150c7de11d201538e179] => Array
        (
            [id] => 1502369241000
            [productid] => SG KENNA
            [qty] => 1
            [type] => purchase
            [user_id] => admin
            [rowid] => 7473a2e4d2e4150c7de11d201538e179
        )    
)

What i need just, check inside array user_id = 'admin' and type = 'sales' are exist.

This is what i try but with no success

$type = array_search('sales', array_column($cart, 'type'));
$user_id = array_search('admin', array_column($cart, 'user_id'));
if($type AND $user_id){
  echo "exist";
} else {
  echo "no exist";
}

Update: I use a loop like this and still no success

foreach ($cart as $item) {
      if ($item['type'] == "sales" AND $item['user_id'] == "admin") {
        echo "exist";
      } else {
        echo "no exist";
      }
    }

try using `in_array()` You can find more here : https://www.w3schools.com/php/func_array_in_array.asp — Rajan, Aug 10 '17 at 13:24
did you trying looping though your array and then finding the element using `in_array` — Rajan, Aug 10 '17 at 13:33

Try using in_array inside a loop:

$cars = array
  (
  array("Volvo",22,18),
  array("BMW",15,13),
  array("Saab",5,2),
  array("Land Rover",17,15)
  );

foreach ($cars as $key => $value) {

 if (in_array("Volvo", $value, TRUE))
  {
  echo "Match found<br>";
  break;

  }
else
  {
  echo "Match not found<br>";
  } 
}

Since you need to do two subsequent checks, it's better if you filter the array and check the result's count. Here's an example of doing this by using an anonymous (lambda) function:

Given that your array is $arr:

$results = array_filter( $arr, function ($entry) {
    return $entry['type'] === 'sales' && $entry['user_id'] === 'admin';
});

then you can check your $results array echo count($results) ? 'exists' : 'does not exist';

Edit:

You can also check for isset($entry['type']) && isset($entry['user_id']) for extra safety in the closure

You can use the below code, which will return an array of results that match the given conditions. Of course, you can return an entire array or some value or whatever you want. You can change and tweak it to your needs:

<?php
$array = array(
    '547650d3bfb9bce7ea6d61faf312fa41' => array
    (
        'id' => 1502369193000,
        'productid' => 'Product 1',
        'qty' => 1,
        'type' => 'sales',
        'user_id' => 'admin',
        'rowid' => '547650d3bfb9bce7ea6d61faf312fa41'
    ),
    '7473a2e4d2e4150c7de11d201538e179' => array
    (
        'id' => 1502369241000,
        'productid' => 'SG KENNA',
        'qty' => 1,
        'type' => 'purchase',
        'user_id' => 'admin',
        'rowid' => '7473a2e4d2e4150c7de11d201538e179'
    )
);

function searchInArray($array) {
   $returnArray = [];
   foreach ($array as $key => $val) {
       if ($val['user_id'] === 'admin' && $val['type'] === 'sales') {
           $returnArray[$key] = $array[$key];
       }
   }
   return $returnArray;
}

print_r(searchInArray($array));
if(isset($array) && !empty($array)) {
     echo 'Found';
} else {
     echo 'None found';
}
?>

you can check this using for loop , it will check your array data that user_id and type is match or not if match then $found true and break and if you want to check one of two is ok then use || condition

<?php
$cart  = array(
    '547650d3bfb9bce7ea6d61faf312fa41' => array
    (
        'id' => 1502369193000,
        'productid' => 'Product 1',
        'qty' => 1,
        'type' => 'sales',
        'user_id' => 'admin',
        'rowid' => '547650d3bfb9bce7ea6d61faf312fa41'
    ),
    '7473a2e4d2e4150c7de11d201538e179' => array
    (
        'id' => 1502369241000,
        'productid' => 'SG KENNA',
        'qty' => 1,
        'type' => 'purchase',
        'user_id' => 'admin',
        'rowid' => '7473a2e4d2e4150c7de11d201538e179'
    )
);

$found = false;
foreach ($cart as $key => $data) {
    if ($data['user_id'] == 'admin' && $data['type'] == 'sales') {

        $found = true;

    }
}

if ($found === false) {
  echo 'not found';
} else {
    echo 'found';
}

Output is : Found

hope it will help you

Try Out This.

    $Your_user_id = searchArrayKeyVal("user_id", 'admin', $YourMultidimensionalArray);
    $Your_type = searchArrayKeyVal("type", 'sales', $YourMultidimensionalArray);
    if ($Your_user_id!==false) {
        echo "Found user_id";
    } else {
        echo "Not Found user_id";
    }

    if ($Your_type!==false) {
        echo "Found type";
    } else {
        echo "Not Found type";
    }

Use this code to get the values

echo $arrayname['547650d3bfb9bce7ea6d61faf312fa41']['user_id'];

echo arrayname['547650d3bfb9bce7ea6d61faf312fa41']['type'];

As I understand from question, `547650d3bfb9bce7ea6d61faf312fa41` would be dynamic and will keep on changing. so you can't really hard-code it inside an array. – Milan Chheda Aug 10 '17 at 13:20
Yes, i dont want to echo the value, i just want to check if exist or not – Andhika R.K. Aug 10 '17 at 13:20
i think it need to dynamic check – Shafiqul Islam Aug 10 '17 at 13:21
you can use my concept to setup a loop as well :-) – Moiz Shafqat Husain Aug 10 '17 at 13:23
If i use a loop, it only catch the lastest array – Andhika R.K. Aug 10 '17 at 13:24

You should try something like this:

foreach($cart as $row) {
    if(!empty($row) && !empty($row['type']) && !empty($row['user_id'])) {
        if ($row['type'] == 'sales' && $row['user_id'] == 'admin'){
            echo "exist";
            $found = true;
            break;
        }
    }
} 
if(!$found){
    echo "no exist";
}
