syntax help with variable

[tomdchi]

I have a script that contains:

 

$systemurl = $_POST['systemurl'];

 

this would be just https://domain.com/

 

later I have:

 

$url = "https://domain.com/includes/api.php";

 

How would I change one of these so that $url would get info from $systemurl and also have /includes/api.php-i.e.,

 

$url = {$systemurl}includes/api.php

 

I have this script working with $url domain completed but this will be used for more than one domain so I need it to pull from the post variable.

echo $_SERVER['SERVER_NAME']; // will echo your domain www.domain.com

 

echo $_SERVER['PHP_SELF']; // will echo everything else /includes/api.php

The variable in question is from a post that contains the system url not of my server but a remote server from where the post came from.  This script uses curl to talk back to the remote site hence the need for it to know where it originated from.

 

When I use $url = "https://remotedomain.com/api.php"; it works fine but I need it to get the url information from the $systemurl variable and append it with /api.php so I can use this script for more than one domain.  Can this be done?

try

<?php
$url = "https://remotedomain.com/api.php";
$url = parse_url($url);
print_r($url);
?>
