PHP Simple Mailer Help

Ok so I am mr.Knownothing when it comes to scripting...

I am trying to modify this script to omit fields that are not filled in. I have checkboxes and text fields.

Here is my current script:

<?php
 
 
    $request_method = $_SERVER["REQUEST_METHOD"];
    if($request_method == "GET"){
      $query_vars = $_GET;
    } elseif ($request_method == "POST"){
      $query_vars = $_POST;
    }
    reset($query_vars);
    $t = date("U");
 
    $file = $_SERVER['DOCUMENT_ROOT'] . "/../data/gdform_" . $t;
    $fp = fopen($file,"w");
    while (list ($key, $val) = each ($query_vars)) {
     fputs($fp,"<GDFORM_VARIABLE NAME=$key START>\n");
     fputs($fp,"$val\n");
     fputs($fp,"<GDFORM_VARIABLE NAME=$key END>\n");
     if ($key == "redirect") { $landing_page = $val;}
    }
    fclose($fp);
    if ($landing_page != ""){
    header("Location: http://".$_SERVER["HTTP_HOST"]."/$landing_page");
    } else {
    header("Location: http://".$_SERVER["HTTP_HOST"]."/");
    }
 
 
 
?>
 
Here is what I think I have to add to it:
 
if (is_array($val)) {
for ($z=0;$z<count($val);$z++) {
 
if(strlen($val[$z])>0) // If the length of your value is greater than
zero, then include it
{ $content .= "$key: $val[$z]\n"; }
 
}
} else {
$content .= "$key: $val\n";
}
 

I am not sure if that is correct or how to add it into the script. Sorry for such an ignorant question.

Maybe empty() would be of interest to you.
