从2个其他变量制作PHP变量

Question

I'm starting a magazine which has 3 editions. UK, US, and European. Each will be published online at different times, therefore each has a different issue number.

So I want to create a way of selecting which issue goes with which edition, but I don't know how to join these 2 parts together. The code I'm using is:

<?php
$this_edition = "UK";
?>

<?php
$UK_issue = "1";
$US_issue = "3";
$EU_issue = "2";
?>

<?php
$this_issue = // The Issue Relating to This Edition
?>

What I want to do here is basically call the issue number ( 1/3/2 ) which relates to the $edition I'm udating, in this case, UK.

So essentially : $this_issue = $edition_issue

Does anyone know how I can do this?

Answer 1

What you're trying to do is possible...

$this_issue = ${$this_edition.'_issue'};

But it's way better to use the solution suggested by pr1nc3.
