Question

I asked this question yesterday: Compare array of words to a textarea input with javascript

Now I want to do the same thing with php…

Is there any easy code for this?

Thanks

UPDATE: I would like to test the textarea input against the array, and if match of bad words found, die();

Thanks

Answer 1

$bad_words = array('first','second','third');

$posted = str_ireplace($bad_words, '****', $posted);

This will replace bad words with ‘****’

EDIT:

to check if any of words from bad_words exist in a string:

foreach( $bad_words as $bad ){
 if( stristr($posted, $bad) !== FALSE )
 {
  $contains_bad_words = TRUE;
 }    
}
