Question

Here is my source

 $Message = $_GET["message"];
 $Username = htmlspecialchars($_GET["username"]);
 $unix = ($_GET["time"]);
 include 'mcheck.php'; 
$file1 = file_get_contents('filter.txt');
$bad_words = explode(PHP_EOL, $file1);
$compare = explode('', $Message);
foreach ($bad_words as $bad_word)
  $Message = preg_replace('/\b('.$bad_word.')\b/i', "***", $Message);
  echo $Message;

Say the bad word is go

and $Message = I Like to go to school

I want it to echo I Like to *** to school

but instead im getting

***I***Like***To******to***school***

i dont know what the problem is

Answer 1

Your file most likely ends with a newline (which is a good thing: all text-files on *nix systems are supposed to), which means that the last element of explode(PHP_EOL, $file1) is empty (it’s everything between the last newline and the end of the file, which is nothing). I would recommend writing:

$file1 = trim(file_get_contents('filter.txt'));

using the trim function to eliminate that last newline.
