Running the following script works: $a = "abc123"; echo ereg_replace("123\0", "asd", $a); as opposed to $a = "abc123"; echo ereg_replace("123", "asd", $a); The unterminated pattern is passed to regcomp which does some weird things with memory/stack etc. Of course, this is only the first source of problems, _php3_regreplace makes heavy use of libc's string functions. -- Regards, Sascha Schumann Consultant -- PHP 4 Beta
