Convert Perl code to PHP code

Hi,

Please help me to convert this Perl code:

use SOAP::Lite;

my %uris = (
    'Session' => "$uri_base/Session",
);

my $session_service = SOAP::Lite
           ->uri($uris{'Session'})
           ->proxy($proxy)
           ;

my $LoginResponse = $session_service->login($login, $password);

my $session_id = $LoginResponse->result();
print "Logged in with session $session_id\n";
exit 0;

Code (perl):

to PHP code. I've tried this:

try{   
    $uris = array("Session" => "$uri_base/Session");

    $session_service = new SoapClient(null, array("location" => $proxy, "uri" => $uris['Session']));

    $LoginResponse = $session_service->login($login, $password);

    $session_id = $LoginResponse->result();

    print "Logged in with session $session_id";
}catch(SoapFault $e){
    print_r($e->getMessage());
}

PHP:

but it returns "Could not connect to host ", when perl works fine.

Thank you.
