I'm trying to edit Open Cart stock levels and I am just a beginner in php.

I am currently displaying the quantity of stock left (numeric only), which is stored within $product_info['quantity'].

$data['stock'] =  ($product_info['quantity']);

This works fine.

I am trying to add text to the end of the quantity so it would say for example 3 remaining in stock:

$data['stock'] =  ($product_info['quantity']) + "remaining in stock"; //(doesn't work)

I don't know the mark up to add text, I've tried a few things and no luck I can only get the number value to show.

    In PHP, + is addition; . is concatenation Commented Jan 7, 2018 at 19:22

    And you don't need any parenthesis like "(" or ")". Commented Jan 7, 2018 at 19:27

You should use . instead of +:

$data['stock'] =  ($product_info['quantity']) . "remaining in stock";

It is explained in the String Operators entry of the PHP Manual:

There are two string operators. The first is the concatenation operator ('.'), which returns the concatenation of its right and left arguments.
