I have this array of associative array’s:

Array { 

    [0]=> array(4) { ["nome"]=> string(35) "ACRILEX TECIDO 37ML AMARELO CANARIO" 
                     ["preco"]=> string(4) "1.65" 
                     ["quantidade"]=> string(1) "1" 
                     ["imagem"]=> string(25) "Loja/imgPQ/4140589589.gif" } 

    [1]=> array(4) { ["nome"]=> string(35) "ACRILEX TECIDO 37ML AMARELO LIM�O" 
                     ["preco"]=> string(4) "1.65" 
                     ["quantidade"]=> string(1) "1" 
                     ["imagem"]=> string(25) "Loja/imgPQ/4140504504.gif" } }

And I wanted to go through it and when I found a name equal to one of the products that returned the position where this associative array is to access its quantity

  • The simplest is through foreach. Have you tried anything?

  • I already got through the foreach with key => value

  • Answers should be in the answer area, not the question.

The simplest way to solve the problem is to walk the array checking the name of each position and, when finding the desired name, return it.

function getKeyFromName($array, $name) {
    foreach($array as $key => $value) {
        if ($value["nome"] == $name) {
            return $key;
        }
    }

    return false;
}

An alternative is to use the functions array_column and array_search together:

function getKeyFromName($array, $name) {
    return array_search($name, array_column($array, "nome"));
}

See working in Ideone | Repl.it

The result will be exactly the same.
