php add variable to array

[PewPew87]

Hey, im struggeling with a small piece of code....

Thats my code:

Global $user_ID;
$user_ID = get_current_user_id();

   echo"User number $user_ID is loggedin";

Echo gives me this:
"User number 2 is loggedin"

 

Now i want to add it to my array:
 

$atts['href'] .=  $user_ID . 'abc';

'href' is set to "https://test.com/"

What im getting now ist

https://test.com/abc

 

Can someone tell my why the '2' is missing??

Not without seeing a contiguous set of code showing us what all is happening.

 

Ps - It's "struggling".

A good thing to NOT do in php is mix upper and lowercases.  This is not JS.   Stick to lower case.

I'm guessing that you do not have error checking turned on and that you mis-typed or misspelled your user id variable.
