PERL to PHP problem

Hi All, I'm trying to convert this snippet of Perl to PHP and it just wont populate the $oid and $status variables. Does anyone know if Perl can do things that PHP can't? - Personally I wouldn't have thought so but you live & learn I suppose. <Perl code starts here> #!/usr/bin/perl use CGI; use DBI; my $qs = new CGI(); #- Print MIME header print $qs->header(); print "<b>Doing Transaction </b><br />\n"; my $oid = $qs->param("oid"); my $status = $qs->param("transactionstatus"); <Perl code ends> The problem is that $oid and $transactionid are just not there. I'm unsure what method the sending server is using. I'm told Java but I have my doubts - It's a banks credit card transaction server so it's kinda secret and it's https which could be the problem. Any help from a Perl guru will be very much appreciated. Cheers Andy.
