为什么我收到HTTP 400错误请求错误？

Question

<?php
$url ="http://absolutesms.com/Sendsms.aspx?userid=userid&password=password&clientid=clientid&senderid=absolute&mobilenumber=919000024365&smsmessage=SingleMessage".$request;
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);
echo $curl_scraped_page;
?>

After running this code I am getting HTTP Error 400. The request is badly formed. What should I do? I tried other url they are working fine the only problem is with this. If I copy this url in browser it's working but it's giving error 400 when I put it and run it in curl.

You are appending $request at the end of the assignment to $url but you don't show us what $request contains.

Chances are that the value of $request tacked on the end that way is making the URL invalid.

I would expect to at least see a & at the end of the hardcoded URL string if you are going to append $request like that (although as @MichaelKrelin-hacker points out, this is unlikely to be the source of this specific error).
