string parsing in between curly bracket

[quote author="Nick_MyShuitings" date="1294216509"]I'm not sure if your question is clear enough to help. Is that in a view,controller etc? Are you using a templating engine?

This php function might be what you're looking for: http://php.net/manual/en/function.sprintf.php

Code:

<?php
$format = 'The %2$s contains %1$d monkeys.
           That\'s a nice %2$s full of %1$d monkeys.';
printf($format, $num, $location);
?>

my bad, what I meant was...

In mysql, I have table named items

|ITEM_ID|ITEM_NAME|ITEM_PRICE|



In CI controller, I have a method-- I want to replace those that requests an item information, and replace it with whatever in the mysql-table above. This replaced string is then passed to a view.

My thinking is similar to CI's templating, except that it should be just implemented as a helper function, of which I just need to find those codes e.g. "{item_name:123}" and replace it with the item_id 123 from the items mysql-table.

and this function actually captures the entire html string contents, and replace whatever needs to be replaced, then return the result to the output view.

Not sure, if I stated it right, I'm a little dizzy right now, thinking as to how can I pull this :|
