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

1) The simplest way:

if ( in_array( 'eleven',  array('four', 'eleven', 'six') ))
...

2) Another way (while checking arrays towards another arrays):

$keywords=array('one','two','three');
$targets=array('eleven','six','two');
foreach ( $targets as $string ) 
{
  foreach ( $keywords as $keyword ) 
  {
    if ( strpos( $string, $keyword ) !== FALSE )
     { echo "The word appeared !!" }
  }
}
