How to print part of an Array PHP

Question

I call a function to get an array and use var_dump()

the result is the following array:

array(1) {
    [0]=> array(12) {
        ["access_id"] => string(1) "1"
        ["invoice_id"] => NULL
        ["invoice_public_id"] => NULL
        ["invoice_payment_id"] => NULL
        ["invoice_item_id"] => NULL
        ["user_id"] => string(1) "1"
        ["product_id"] => string(1) "2"
        ["transaction_id"] => NULL
        ["begin_date"] => string(10) "2015-12-24"
        ["expire_date"] => string(10) "2016-01-24"
        ["qty"] => string(1) "1"
        ["comment"] => string(0) ""
    } 
}

I only need this part :

["product_id"]=> string(1) "2"

How can i get that part only from the array?

If you only want `product_id` you can just use a simple echo to print the key and value in that specific format. `var_dump()` is a debugging function to show the entire array. — Rizier123, Jan 07 '16 at 22:43
Please: 1. format your code; 2. read the [docs on php arrays](http://php.net/manual/en/language.types.array.php) — ArSeN, Jan 07 '16 at 22:44
echo $array[0]['product_id']; Yes mate this is correct. I was doing it like this : echo $array['product_id'][0]; and it wasn't working. Thanks a lottt. — jamesll, Jan 07 '16 at 22:50
@jamesll So you just want to access the `product_id`, it's not about that specific format? — Rizier123, Jan 07 '16 at 22:52
@Rizier123 No no i just wanted the "2" at the end. I am noob. — jamesll, Jan 07 '16 at 22:55

You can simply access the value directly:

echo $myArray[0]['product_id'];

You may want to start reading the documentation about arrays in php: http://php.net/manual/en/language.types.array.php

var_dump($yourArray[0]['product_id']);

You should not use var_dump for production, only for debugging.

This will give OP an undefined index – Rizier123 Jan 07 '16 at 22:46

Undefined index fixed. – Antonin Blaise Jan 12 '16 at 18:41
