PHP not able to redirect to url which contains colon

Question

I am trying to redirect to url

<?php
$url = "https://icommand://?username=Sachin";
header("Location: ".$url."");
?>

But when I try this one it redirect to me this url http://icommand//?username=Sachin. The colon does not come after icommand. I have tried but doesn't get solution.

A quick search found this - http://stackoverflow.com/questions/19060002/escape-colon-in-url-string - Google is your friend — Blinkydamo, Nov 03 '16 at 13:04
why would you redirect to icommand: that makes no sense. I think your browser removes the : — mirko911, Nov 03 '16 at 13:05
what's the trailing colon supposed to do? after the colon should go the port number.. something like `https://icommand:443/` — Johnny, Nov 03 '16 at 13:05
It may be because that's not a valid URL. A colon is not allowed in the hostname — apokryfos, Nov 03 '16 at 13:09

This will work:

<?php
     $url = "//icommand://?username=Sachin";
     header("Location: ".$url."");
?>

try this: urlencode();

$url = "//icommand://?username=Sachin";
header("Location: ".urlencode($url)."");

It's wrong. It is redirecting to http://localhost/test/%2F%2Ficommand%3A%2F%2F%3Fusername%3DSachin – Sachin Sharma Nov 04 '16 at 06:38
this url is "url encoded" all the special symbol are encoded when you decode the url you will get the same "//icommand://?username=Sachin" refer http://php.net/manual/en/function.urlencode.php – Amit Kumar Sahu Nov 04 '16 at 07:56
