Remote mail() function - php

Question

I am trying to use my localhost to connect to another server remotely and execute a mail function so i use get method to send the email and the subject
here is my localhost file :
<?php
for ($email=0; $email< $n_emails; $email++){
$urlsmtp = $link.'?email='.$destino.'&subject='.$tornado.'&msg='.$msgrand.'&name='.$_POST['naming'].'&from='.$_POST['localting'];
//this link is something like http://test.com/RemoteSmpt.php?email=test#mail.com &subject=test&msg=test&name=test&from=test
$urlsmtp = str_replace(" ", "%20", $urlsmtp);
$response = file_get_contents($urlsmtp);
}
?>
and the file RemoteSmpt.php which i will put it in the server contains this code :
<?php
if ( isset( $_GET['email']) && $_GET['subject'] && $_GET['msg'] && $_GET['name'] && $_GET['from']) {
$email = $_GET['email'];
$subject = $_GET['subject'];
$msg = $_GET['msg'];
$name = $_GET['name'];
$from = $_GET['from'];
$headers = 'From: '.$name.'<'.$from.'>\n';
$enviar = mail($email, $subject, $msg, $headers);
if ($enviar){
echo ('<font color="green"> -'. $email .' 0k -- With Subject : '.$subject.'</font><br>');
} else {
echo ('<font color="red"> -'. $email .' Not Sended -- With Subject : '.$subject.'</font><br>');
}
}else
{echo 'Invalid Data !<br>';}
?>
so after i upload the RemoteSmpt.php file and try this is what i got :
Warning: file_get_contents(http://...#mail.com&subject=tset&msg=test&name=test&from=test): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found in Mylocalhost file !
Please any idea how to fix this code !

You need to properly encode special characters in the URL parameters, which can be done using urlencode().
You can use the http_build_query() function to build a query string from an associative array, and properly encode everything.
$params = http_build_query([
'email' => $destino,
'subject' => $tornado,
'msg' => $msgrand,
'name' => $_POST['naming'],
'from' => $_POST['localting']
]);
$urlsmtp = $link . '?' . $params;
