PHP过滤坏词

Question

I have a filter bad words codes below I want to replace this ARRAY with the .txt file so that I can put all the bad words into the txt file or is there any way to use MYSQL database to store the badwords and then call from there ?

FUNCTION BadWordFilter(&$text, $replace){

 $bads = ARRAY (
      ARRAY("butt","b***"),
      ARRAY("poop","p***"),
      ARRAY("crap","c***")
 );

 IF($replace==1) {                                        //we are replacing
      $remember = $text;

      FOR($i=0;$i<sizeof($bads);$i++) {               //go through each bad word
           $text = EREGI_REPLACE($bads[$i][0],$bads[$i][1],$text); //replace it
      }

      IF($remember!=$text) RETURN 1;                     //if there are any changes, return 1

 } ELSE {                                                  //we are just checking

      FOR($i=0;$i<sizeof($bads);$i++) {               //go through each bad word
           IF(EREGI($bads[$i][0],$text)) RETURN 1; //if we find any, return 1
      }     
 }
}

$qtitle = BadWordFilter($wordsToFilter,1);

Yes make a file like bad_words.txt with entries like (note each word combo is on a separate line):

butt,b***
poop,p***
crap,c***

Then read that file into an array like so:

$file_array = file('/path/to/bad_word.txt');

Then to create an array like your $bads array do this:

$bads = array();
foreach ($file_array as $word_combo) {
    $bads[] = explode(',', $word_combo);
}

Hope this helps.
