Question

I am doing a site for publishing ads, in a section of adding the campaign (ads) I need to prevent certain badwords from the campaign title. So I have checked those title when the advertiser adds the campaign. These badwords are stored in a file in txt format. I have used this code.

$string = $description;

$badwords = file( "badwords.txt" );
if ( $badwords ) { 
  foreach ( $badwords as $line ) {  
    if ( preg_match("/$line/", $string) ) { 
      echo $string; die();
      return array ( 0, $language['bad_words_error'] );
    }
  }
}

I have tried in_array() but i can’t match the content in $string.

if ( in_array($string, $badwords) ) { 
  echo "The word ".$string ." is a bad keyword"; 
}

Usually, the problem comes from trailing spaces left in the file.

To solve this, use trim() on individual $lines.
