Where is the modifier "/e" in preg_replace() (Andrei?) ?

Hi, I am trying to use the modifier "/e" in the function preg_replace(). My code looks like: $variable=preg_replace('/\\{EDIT:(PPP)\\}/e',"my_function('\\1')",$variable); I get the following error: Warning: Unknown option 'e' in library.php on line 169 Unfortunately, it isn't just a "warning": the function my_function() doesn't get called at all. In the "NEWS" file, I read: 8 May 2000, Version 4.0 Release Candidate 2 [...] - Put in safeguards in case dynamic code evaluation in assert() and preg_replace() with /e modifier fails. (Andrei) [...] ...any idea? If I were able to use that modifier, my life would be *much* easier!
