hi

i'm a php newbie, not sure if anyone can help but it would be greatly appreciated..... i want to load 2 files into arrays (that works) and then use array_diff to create a new array like this:

$words = file ('./words.txt');
$bannedwords = file ('./bannedwords.txt');
$words2 = array_diff ($words, $bannedwords);

but the banned words need to be wildcards e.g. if

$words = ("hello to you", "goodbye to you", "phrase with swearword");
$bannedwords = ("badword", "swearword");

the output produced would be:

$words2 = ("hello to you", "goodbye to you");

i.e. "swearword" would become "%swearword%" in the $bannedwords array.

i am not sure how to do that, can anyone help? Thnaks in advance.

    <?php

$words = file ('./words.txt');
$bannedwords = file ('./bannedwords.txt');
$words2 = '';
settype($words2,"array");


for($i=0;$i<sizeof($words);$i++) {
   for($j=0;$j<sizeof($bannedwords);$j++) {
      $bw = $bannedwords[$j];
      if(!preg_match("/$bw/",$words[$i]) ) {
         $words2[] = $words[$i];
      }
}

// your output...
?>

    Now, I hate to use nested loops because the execution time will increase exponentially as the number of items increases...

    But anyway, there's an idea 🙂

      thanks tbach, that looks good for my needs, i'll give it a try.

      thanks again.
