I have this code:

PHP Code:


			
<?php

                    

$myFile = "quotes.txt";

$fh = fopen($myFile, 'r');

$ToFilter = fread($fh, filesize($myFile));

fclose($fh);

function LangFilter($ToFilter)



{



   // Open the foul.txt for extracting the foul words



   $Foul = @file("foul.txt");



   // Loop through the foul words



   foreach ($Foul as $FoulWord)



   {



      // Store the current foul word in a variable



      $FoulWord = trim($FoulWord);



      // If there's a match for the fould world inside the string



      if (preg_match("/".$FoulWord."/i", $ToFilter))



      {



         // Get the word length, so that we know how many characters



         // we need to replace with asterisks



         $WordLength = strlen($FoulWord);



         // Loop through the word's characters



         for ($i = 1; $i <= $WordLength; $i++)



         {



            // Replace the characters of the foul word with * (asterisks)



            $RepChar .= "*";



         }



         // Replace the dirty string with the filtered string



         $ToFilter = eregi_replace($FoulWord, $RepChar, trim($ToFilter));



         $RepChar = "";



      }



   }



   // Return the new string



   return $ToFilter;



}

echo $ToFilter;

?>

quotes.txt is data that is to be loaded to the page and foul.txt is a text file containing all words that are to be filtered. Although its not working... obviously its not right could somone plz correct me, new to php!
