PHP get values from array

Question

Im return an array from a function and I want to grabe the elements in the array and store them as varibles.

When I do a:

$array = fetchArray();
var_dump ($array);

I get this:

array(size = 1)
0 =>
    array(size = 1)
0 =>
    array(size = 7)
'customerid' => string '31' (length = 2)
'username' => string 'test' (length = 4)
'active' => string '1' (length = 1)
'CustomerName' => string 'Tobias Axbard' (length = 13)
'email' => string 'tobias.axbard@hotmail.com' (length = 25)
'phonenumber' => string '0738032207' (length = 10)
'isstaff' => string '0' (length = 1)

So than I would like to do something like this:

$username = $array["username"];
echo $username;

But insted of the string "test" from the array I get an error:

Notice: Undefined index: username 

Any ides?

Answer 1

Well, youre array is nested, so an array in an array in an array.

Most outer array is $array. The first element of $array, $array[0], is an other array, and that one contains again another one as first element $array[0][0] which contains the data you want to access.

So you'll have to use $array[0][0]['username'] to access the values.

Use $array = $array[0][0] to 'move it up', or even use extract($array[0][0]) to immediatly convert the array keys to variables: https://www.php.net/manual/en/function.extract.php

Note that $array has two nested arrays inside it which you need to access:

$username = $array[0][0]["username"];
