How can I output specific data from an associative array in PHP using foreach

My associative array:

$products = array();
$products[101] = array(
    "name" => "Red Shirt",
    "img" => "img/shirts/shirt-101.jpg",
    "price" => 18
);
$products[102] = array(
    "name" => "Black Shirt",
    "img" => "img/shirts/shirt-102.jpg",
    "price" => 20
);
$products[103] = array(
    "name" => "Blue Shirt",
    "img" => "img/shirts/shirt-103.jpg",    
    "price" => 20
);

So, let's say I wanted to output the name of the ALL products array like this:

Red shirt, Black shirt, Blue shirt

How can I achieve this with a foreach loop? I tried to output only a specific key from all arrays at the same time, but I cannot do it without outputting all keys.

You can also say that I just wanted to output the "price" of a specific array, eg $ products [103], how can I achieve this?

Thank!

you can use below code using foreach 

foreach($products as $pro)
{
    echo $pro['name'];
}

above code will only print name

the product array key

to get the price $product['103']

you can use as below code

foreach ($products as $key => $value)
{
    if ($key == '103')
    {
        echo $pro['price'];
    }
}


EDIT : get an array of names

$names = array();
foreach ($products as $pro)
{
    $names[] = $pro['name'];
}
print_r($names);

he will return

Array ([0] => Red shirt [1] => Black shirt [2] => Blue shirt)

let me know if it helped you

try it

foreach($products as $key => $val) {
    // For name
    echo $val['name'];

    // For specific product price
    if($key == 103) {
        echo $val['price'];
    }
}

Let me know if there are any problems.

Try the following code (This will cover all scenarios) :

function getMyArray($key, $arr = array()){
    $result = array();
    foreach($arr as $arrVal){
        $result[] = $arrVal[$key];
    }
    return implode(", ", $result);
}

echo getMyArray('name', $products);  // Red Shirt, Black Shirt, Blue Shirt
echo getMyArray('img', $products);   //path1, path2, path3
echo getMyArray('price', $products); // 18, 20, 20

If you want to get a specific value:

echo $products[103]['price']; // 20

Try this

foreach ($products as $prd) {
        echo $prd['name'];
}
0


source 


$productNames = array();
foreach($products as $key=>$product) {
    $productNames[] = $product['name'];
}

//all names with comma

echo implode(',',$productNames);
echo "\n";

//only price of $products[103]

echo $products[103]['price'];

Result:

Red Shirt, Black Shirt, Blue Shirt
20
0

you will get the same as you by this code

foreach($products as $key=>$result)
{

    echo $result['name'].', ';
}

Output:

Red Shirt, Black Shirt, Blue Shirt
