I whipped this together, it should work ok. You'll want to clean it up,
but you get the gist.

<?php
/* AC Was here */

$str="I'm going to the store to buy some stuff.";
$bold=array("store","some","stuff");

function boldWord($str,$bold) {
   if(isset($str)) {
       foreach($bold as $b) {
         echo "$b should be <b>$b</b>\n";
               $str = eregi_replace($b,"<b>$b</b>",$str);
       }
       $string=$str;
       return $string;
   } else {
       $string='The inputed variable $str was empty.';
       return $string;
   }
} // End function bracket

// Example usage
if(isset($str)) {
         $string=boldWord($str,$bold);
         echo "Original: $str \n";
         echo "New: $string\n";
} else {
         echo "Variable str not set.";
}
?>
