From 0858fb4b73021854c3ab21adae6252ec67f57fc1 Mon Sep 17 00:00:00 2001 From: Andrei Zmievski Date: Tue, 18 Dec 2001 19:17:57 +0000 Subject: [PATCH] @- Added flags parameter to preg_grep(). The only flag currently is @ PREG_GREP_INVERT that will make the function return entries that @ did not match.
