php array index giving errors

Question

I have created a php array, and var dumped it. In the var dump, I can see a item, but when I try to access that Item, it gives a php error. Here is the var_dump.

array(16) {
    [0]=>
    string(1) "3"
    ["id"]=>
    string(1) "3"
    [1]=>
    string(2) "11"
    ["price"]=>
    string(2) "11"
    [2]=>
    string(13) "Title"
    ["name"]=>
    string(13) "Title"
    [3]=>
    string(15) "String"
    ["seller"]=>
    string(15) "String"
    [4]=>
    string(1) "0"
    ["category"]=>
    string(1) "0"
    [5]=>
    string(347) "String"
    ["description"]=>
    string(347) "String"
    [6]=>
    string(69) "String"
    ["img"]=>
    string(69) "String"
    [7]=>
    string(1) "0"
    ["stock"]=>
    string(1) "0"
}

This piece of code is giving the error. Any help would be nice.

$array["img"]

Error Log:

Code:

var_dump($product);
echo $product["img"];
echo '<div class="card">
    <img class="card-img-top" src="'.$product["img"].'" alt="'.$product["name"].'" style="height: 200px;">
        <div class="card-block">
            <h4 class="card-title">'.$product["name"].'</h4>
            <a href="#" class="btn btn-primary">Buy Now</a>
        </div>
    </div>';
// The array is stored in product.

Try $array[0]["img"] , undefined index means you are not specifying the index of the element hence [0] — RedCrusador

How did you create that aarray. It looks wrong where it says ["img"]=> string(69) "String" — RiggsFolly

Try $array[0]["img"] , undefined index means you are not specifying the index of the element hence [0]

For future reference use php.net , here is the page for arrays http://php.net/manual/en/function.array.php
