Question

I am new to PHP,
And am creating a data string, which i have written like this.

$data = $product['id']. "/" . $product['name'] . "/" .$product['price'];

I don’t know if there is another better way to create this String.

Answer 1

PHP can interpolate array values inside double quotes if they are surrounded with {}:

$data = "{$product['id']}/{$product['name']}/{$product['price']}";

If you remove the quotes around the keys you don’t need the curly braces and it will become even simpler:

$data = "$product[id]/$product[name]/$product[price]";
