Check if string contains word in array

Question

This is for a chat page. I have a $string = \"This dude is a mothertrucker\". I have an array of badwords: $bads = array(\'truck\', \'shot\', etc)

Answer 1

There is a very short php script that you can use to identify bad words in a string which uses str_ireplace as follows:

$string = "This dude is a mean mothertrucker";
$badwords = array('truck', 'shot', 'ass');
$banstring = ($string != str_ireplace($badwords,"XX",$string))? true: false;
if ($banstring) {
   echo 'Bad words found';
} else {
    echo 'No bad words in the string';
}

The single line:

$banstring = ($string != str_ireplace($badwords,"XX",$string))? true: false;

does all the work.
