PHP 4.0 Bug #3014 Updated: octal character versus regex backreferences

ID: 3014 Updated by: jimw Reported By: cmiller@surfsouth.com Old-Status: Open Status: Closed Bug Type: Feature/Change Request Assigned To: Comments: the backreference needs a double backslash, and then there's no confusion. Previous Comments: --------------------------------------------------------------------------- [1999-12-20 21:18:57] cmiller@surfsouth.com ereg("fla(r[gpm]) wobba1", $foo) Note the ``1'' -- is that an octal 1 in my charset, or a backreference? The backslash-x-number notation is great for hexidecimal, but the backslash-number notation conflicts with the notation for backreferences (in ereg(), e.g.) Are there backreferences? The manual refers us to the regex(7) manpage, which does describe them. Even if there's not, I recommend backslash-zero-octal, as historically, octals are represented with preceding zeros. Backreferences are positive integers (which mortals usually describe with no leading zero), so there's no conflict. --------------------------------------------------------------------------- ATTENTION!
