Strings and patterns

[gunnerh]

I need some php code.

I only know the basics of PHP and need what hopefully might
just be a few lines of code.

I would be grateful if someone could supply.

(My head is spinning with ereg pattern matching)


The requirement:

--------------------------------------------------------
I have a string which can contain any number of 'tokens'.
A token is text enclosed by {}

So for example

==> Hello {abc}, goodbye {def}

I want to remove the {} and replace each token
with a string derived from the token.

So I end up with

==> Hello xxx, goodbye yyy

where xxx = function (abc)
yyy = function (def)
--------------------------------------------------------

Thanks

Hi

Use [tt]preg_replace_callback()[/tt] instead :

$s='Hello {abc}, goodbye {def}';

echo preg_replace_callback('/\{([^{}]+)\}/',whatever,$s);

function whatever($what)
{
  return strtoupper($what[1]);
}
