Parser question

[Paul Czubilinski]

Hello,

I would like to make a simple parser which should work as follows:

this is my text {link:href=mypage,link_text} some other text
{link:href=otherpage,other_description}

/|\
|

This is a string I would like to store in the database and then load
in php. Later I would like to insert some other text between { and }
signs. I would have a function name "link" with one parameter passed.
Return value of this function would be a string to replace that one
between { and } signs.

function link($params)
{
... some logic ...
return string;
}

This function will return something like <a
href="/mydir/some_file.php">link_text</a>

Is there any easy way to do it?

Paul
