PHP: preg_replace_callback

[Newsgroup_User]

Does anyone know to how write this properly, or indeed if it can be done?

In plain English ......

if $pattern = "/\{@([^\}]*)\@}/";
return preg_replace_callback($pattern,'getFileSize',$str);
else
if $pattern = "/\{:([^\}]*)\:}/";
return preg_replace_callback($pattern,'getName',$str);


Trying to search for two possible string combinations within a larger string
and run different callbacks depending on the result, within the same larger
string.
I suspect I may have to break out of the callback 'getFileSize' and branch
to 'getName' if the $pattern is wrong, but damned if I know how.

In case anyone's interested, the answer seems to be:-

<?php function changeMe($str){
$str = preg_replace_callback('/\{@([^\}]*)\@}/','getFileSize',$str);
$str = preg_replace_callback('/\{:([^\}]*)\:}/','getName',$str);
return $str;
}
?>

No doubt there's a more elegant solution, but for now ... at least it works.
