Clearing pipe stream and a few other issues.

ok, I'm not sure how to explain this but here goes.. I have a php script being used as a cgi to get around certain permission issues. Its not what I wanted but is basically working. Running through the cgi-bin has been much more difficult however, for example, 1. I need to clear or reset the stream because on occasion, I am get variables from a previous submission to the form. Not sure how to do this. 2. I have having trouble using the header function. Its says that the header is already been sent. I can only assume at this point its because of the #!/usr/local/bin/php -q at the top of the script required for cgi's. I may be wrong. I may not even need the header. 3. The formatting is coming out in plain text..The html code is not executing. Here again I believe its a header content issue. here is the code: <? echo " <H1 align=center>Thank You, $sender_name</h1> <p align=center>Your secret message has been sent.</p>"; ?> here is the result: <H1 align=center>Thank You, David</h1> <p align=center>Your secret message has been sent.</p> I am rookie at php, so any insights, workarounds or help is appreciated. Thanks in advance, Zed <? $fp=popen("cat","r"); $str=fgets($fp); pclose($fp); print $str; $arr = array(); foreach (explode('&', $str) as $v) { $split = explode('=', $v); // urldecode content for readability $arr[$split[0]] = urldecode($split[1]); // create assoc. array ${$split[0]} = urldecode($split[1]); // form the variables } //echo $sender_name . '<br/>' . $arr['sender_name']; print_r($arr); $msg = "Sender's Full Name: $sender_name\n"; $msg .= "Sender's E-Mail: $sender_email\n"; $msg .= "Secret Message? $sender_msg\n\n"; ?>
