This tutorial will show you how to load a flat file and parse text to highlight or even censor out a word.

First step is to create an empty folder and create two text files. The first one rename it to badwords.txt, and the second as index.php

fopen("badwords.txt","r"); //Open the file that contains the words
while($word = fgets($fh,4096))
  {
  $message = ereg_replace(trim($word),"<b>$word</b>",$message); //replace words

return $message; //return censored words
}
echo censor($message);
?>

Access the index.php through your localhost address, or web page, abd you should see the following:
