How to parse PHP tags in a string?

Hi all, Is there a PHP function that parses a string as it was the content of a PHP file? I have a CMS application and editors write the news items text into a text area. Since they have some knowledge of PHP, I'd like to allow them to insert <? ... ?> or <?= ... ?> and have the content blocks parsed and executed. OK, this could be easily done parsing the string and passing the block contents to eval(). However I wonder wether there is some function already doing that (maybe in a more efficient way). Thanks a lot in advance. =============================================================================== Marco Brandizi [marco_AT_leafbioscience_DOT_com] http://gca.btbs.unimib.it/brandizi
