Simple PHP help

[intenseone345]

Hello, how would i go about "Joining" these two scripts shown below, the idea is to reject and not post the comment if trigger words are found, and maybe add an alert or just redirect back to the comment input page without posting the comment, redirect command would be prefered, any help would be greatly appreacated.

simple php-word trap

<?php
$words = array(

   'bad1',
   'bad2',
   'bad3',

);

  $continue = true;

  foreach ($words as $word) {

  if (preg_match('/\b' . $word . '\b/i', $post)) {
      $continue = false;
      exit();
      }

}

   if (!$continue) {
     // Bad boy!
   }

   else {
     // Post message
   }
?>

joined to this php code "fopen fclose" and "email me" php code?

<?
$fc = fopen("comments.txt","a+b"); //opens the file to append new comment - 
fputs($fc,$_POST['comments']."\n\n\nNewComment->"); //writes the comments followed by a 


fclose($fc); //closes the files

if(sizeof($_POST)) {
$body = ""; 
while(list($key, $val) = each($HTTP_POST_VARS)) {
$body .= "$key: $val \n";
}

mail("[e-mail]", // to
"Subject Line",
$body);

header("Location: myproject.html");
}

// end form processing
?>

I would say wrap the first bit of code in a [man]function[/man] which returns boolean true or false (you can decide the logic; obviously one value means the script should continue with the post while the opposite value means it should not).

Then, in the second bit of code, you'd call that function with the submitted data and, depending on the return value of the function, continue on with processing or display an error message.
