As a matter of fact, you don't need to use eval() if you want to call a function whose name is in some variable, say $function. You just need to call $function(...); An obvious example (with some interesting implications): <? $repository = new Repository(); $function = $_REQUEST[operation]; echo $repository->$function( $_REQUEST[id] ); ?> One must put all functions that can be called at the class Repository. It's not a good idea to do <? $_REQUEST[operation]() ?> or the user can run anything he wants to (my own experience here) =) ---- Manual Page -- http://www.php.net/manual/en/function.eval.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+59338 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+59338&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+59338&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+59338&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+59338&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+59338&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+59338&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+59338&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+59338&report=yes Search -- http://master.php.net/manage/user-notes.php
