如何用http_build_query构造url，但显示没有变量的值？

Question

I'm trying to generate an URL from all values of two arrays by using http_build_query:

Array 1:

$server = array($_GET["server"]);

Array 2:

$data = array($_GET["z_koord"],
        $_GET['x_koord'],
        $_GET["y_koord"],);

The code for generating URL I currently have written:

$server = array(''=>$_GET["server"]);
$data = array($_GET["z_koord"],
        $_GET['x_koord'],
        $_GET["y_koord"],);
$url = '.tile.openstreetmap.org';
$saite = http_build_query($server). $url ."/". http_build_query($data,'','/').".png";

Here's the URL made of code above:

=c.tile.openstreetmap.org/0=6/1=90/2=110.png

Here's the structure of url I'm trying to make:

c.tile.openstreetmap.org/6/90/110.png

I have reviewed some other posts about this topic like this one and this, but those posts aren't completely useful for solving my problem.

So I hope someone with greater knowledge could show me a solution or at least a hint how to get closer to solution.

Answer 1

You could use implode():

$server = $_GET["server"];
$data   = [$_GET["z_koord"],
           $_GET['x_koord'],
           $_GET["y_koord"]];
$url    = '.tile.openstreetmap.org';
$saite  = "$server/$url/" . implode('/', $data) . ".png";

I'm not sure about some things in this code, but the implode() should do the job.
