Function to search multiple keys in an associative Array?

Question

I have an array in this format:

Array ( [0] => Array ( [NUMBER] => 1 [AMOUNT] => 5 [RATE] => 1 ) [1] => Array ( [NUMBER] => 2 [AMOUNT] => 10 [RATE] => 1 ) [2] => Array ( [NUMBER] => 3 [AMOUNT] => 15 [RATE] => 1 ) )

I can loop thru array and can find the desired result but I am rather looking for some builtin function or function provided by Laravel.

Is there efficient and small way to search this array if it's given two inputs: NUMBER = 3 and AMOUNT = 5 then it returns either true/false or that particular value?

What is your expected output? What you have tried so far Post your attempts too? — Narendrasingh Sisodia

@Uchiha I could loop thru arrays and find values but issue is that some built-in function or function provided by Laravel to perform this job. — Volatil3

you could try array_filter, but this function will return a filtered array instead of true/false. — ILadis

echo count(
    array_filter(
        $your_array, 
        function ($e) {
            return $e['NUMBER'] == 3 && $e['AMOUNT'] == 5;
        }
    )
);

should do the trick

Test:

$fooArray = array(
    array(
        'NUMBER' => 1,
        'AMOUNT' => 5
    ),
    array(
        'NUMBER' => 2,
        'AMOUNT' => 10,
    ),
    array(
        'NUMBER' => 3,
        'AMOUNT' => 15
    )
);

$barArray = array(
    array(
        'NUMBER' => 1,
        'AMOUNT' => 5
    ),
    array(
        'NUMBER' => 2,
        'AMOUNT' => 10,
    ),
    array(
        'NUMBER' => 3,
        'AMOUNT' => 5
    )
);

echo count(
    array_filter(
        $fooArray, 
        function ($e) {
            return $e['NUMBER'] == 3 && $e['AMOUNT'] == 5;
        }
    )
);
//will echo 0

echo count(
    array_filter(
        $barArray, 
        function ($e) {
            return $e['NUMBER'] == 3 && $e['AMOUNT'] == 5;
        }
    )
);
//will echo 1

If you want the true/false logic, just add a (true == ) or (false == ) test instead of echoing it

Short and Sweet. I tried array_intersect but give Array to String Conversion error.
