Here is what I want to do:

Search and replace words via an array, like:

$s[]="this";
$r[]="that";

str_replace($s, $r, $string);

But I am having a problem because I need it to be case insensitive and I also need to still replace the word if there is say a period or exclamation point after or before it. I know I'm going to have to use REGEX but I don't know how to use REGEX worth a damn, can someone give me some sample code to work with? I'm already tried the PHP manual and all and didn't find much to work with.

Thanks in advance!

    <?
function stri_replace($find,$replace,$string)
{
       if(!is_array($find)) $find = array($find);
       if(!is_array($replace))
       {
               if(!is_array($find)) $replace = array($replace);
               else
               {
                       // this will duplicate the string into an array the size of $find
                       $c = count($find);
                       $rString = $replace;
                       unset($replace);
                       for ($i = 0; $i < $c; $i++)
                       {
                               $replace[$i] = $rString;
                       }
               }
       }
       foreach($find as $fKey => $fItem)
       {
               $between = explode(strtolower($fItem),strtolower($string));
               $pos = 0;
               foreach($between as $bKey => $bItem)
               {
                       $between[$bKey] = substr($string,$pos,strlen($bItem));
                       $pos += strlen($bItem) + strlen($fItem);
               }
               $string = implode($replace[$fKey],$between);
       }
       return($string);
}

//For example:
$foobar = 'FoO FOO foo bAr BAR bar';
echo stri_replace(array('foo','bar'),'woggle',$foobar);

// echos 'woggle woggle woggle woggle woggle woggle'
?>
