Take a look, You just need to combine them so that you can make the variable name and then use the $ before that name to make it is a PHP variable.

$bun1 = "home";
$x = "1";
$h = ${"bun".$x};
echo $h;

You can also do the same thing like this way--

$bun1 = "home";
$x = "1";
$h = "bun".$x;
echo $$h; // this is called variable of variable. In `$h` you have only the 'bun1' and when you use a `$` before it it will be the `$bun1` and the value is `home`.

What you're trying to do is called variable variables.

PHP.net has a whole page on it.

<?php
$bun1="home";
$x="1";
$h= ${"bun".$x};
echo $h;
?>

Thing is though, from a design standpoint, you're almost always doing it wrong if you're using variable variables. Use arrays instead:

<?php
$bun[1] = "home";
$x=1;
$h= $bun[$x];
echo $h;
?>

If you're just trying to learn, then okay, have at it.
