‘{1}’ prefixed to the date of all posts after 2.0.3 upgrade

I’m experiencing the same problem.

I think it’s related to ticket #2564, which was included in the 2.0.3 release, but I don’t know why this is happening.

Edit: my date format is: “j F Y”

I’ve changed the fixes from that ticket back to the way they were in 2.0.2 and that solved the issue for me.

I think it’s a ‘useless’ fix anyway, because I don’t know of any regional setting where the name of a day or a month (see below) start with a literal number, thus making the fix void anyhow, except maybe for esthetics.

The replace takes place on:
D (A textual representation of a day, three letters)
F (A full textual representation of a month, such as January or March)
l (A full textual representation of the day of the week)
M (A short textual representation of a month, three letters)

Thanks for bring that ticket to my attention Nazgul, I didn’t think to search there. I reverted back the ‘fix’ and it seems to be working now for me as well.

Same problem here. Reverted the “fix” just like Nazgul and all is well now.

Good find Naz.

What version of PHP are you all running?

As far as I can tell from (https://uk.php.net/preg_replace) the \{1} format for referring to backreferences in the regular expressions should work fine on PHP 4.0.4.

I’m running on PHP 4.1.2 and my PCRE library version, specified in phpinfo, is 3.4 22-Aug-2000.

I found the following when I did a diff on wp-includes/functions.php. The 2.0.3 version is on top, the previous version is on bottom:

Starting around line 35 or so in functions.php and continuing for about 5 lines are \${1} in the function call. In the previous version, it was \\1.

Changing the \${1} to \\1, as it was in the previous version fixed things. I’m running PHP 4.1.2.

Did the above mod – worked for me too! Thanks!

Using php 4.2.2
mysql 4.1.18
Apache 2.0.40

Nazgul, this related ticket confirms that some regional settings do need this change.

Adding to the chorus, this fixed my problems as well using PHP 4.2.2

As far as I can tell from (https://uk.php.net/preg_replace) the \{1} format for referring to backreferences in the regular expressions should work fine on PHP 4.0.4.

Nope. PHP 4.0.4 added the ability to use $ddd backreferences, but the “perl-style” of ${ddd} was not added until PHP 4.3.0.

From here: https://www.php.net/ChangeLog-4.php
Added ability to use Perl-style ${n} subpattern references in the replacement string for preg_replace() (bug #18442). (Andrei)

So the short of it is: Upgrade your copy of PHP, for crying out loud! ??

If you need at least 4.3.0 to get this to work, somebody should also update the Requirements page, because there it says at least 4.2.0.

But I’m not in a position to upgrade my PHP version, so I’ll just have to live with my ‘hack’ in this, and possible future versions, for now.

The hack seems to work OK – I’m not particularly familiar with php – what was the change meant to implement?

The “\\1” fix helped my site out.

Thanks!

what was the change meant to implement?

It’s a bugfix that is mostly intended for Non-English users. It won’t impact English users *if* they have a version of PHP later than 4.3.0.
