Change some words in a feed

Hey Co - Webmasters,

Sinds last week I tried to make a script (in php with some sql)
that can rewrite a feed so that some words change automatic.
And that the new feed can put in web 2.0 app like netvibes.

Example: Rss Feed - attendance at special course
To Feed - to be there at special course

Is it difficult to make something? I tried but with no success.
I hope that someone know how it can work.

 

It's not difficult, but takes some time.

Create an array with words to search for and words to replace

for example

$text = 'the bad line that needs to change words';
$arr = array("word" => "new-ord", 
                 "bad" => "good",
                 "true" => "false");

foreach ($arr AS $search => $replace)
{
    // replaces words / multiple words
    $text = str_replace($search, $replace, $text);
}

Code (markup):

hope this works for you!
