Fixing "Use of undefined constant jq_syntax_htmlentities"

Leave a reply

I upgraded the PHP version backing my WordPress setup to PHP7.3. Of course, something had to go wrong:

Warning: Use of undefined constant jq_syntax_htmlentities - assumed 'jq_syntax_htmlentities' (this will throw an Error in a future version of PHP) in ...... wp-content/plugins/jquery-syntax/jquery-syntax.php on line 37

There’s no updates for jquery-syntax plugin that I’m using. Let’s assume that the author will fix this if they ever release an update.

For the time being, opening jquery-syntax.php manually and editing jq_syntax_quote to replace passing what looks like a function object (is it in PHP? I can’t be bothered to check) with a string when invoking preg_replace_callback() does the trick:

function jq_syntax_quote($content) {
        $content = preg_replace_callback('/<(pre)(.*?)>(.*?)<\/pre>/imsu','jq_syntax_htmlentities', $content);
        $content = preg_replace_callback('/<(code)(.*?)>(.*?)<\/code>/imsu','jq_syntax_htmlentities', $content);

        return $content;
}

Note how jq_syntax_htmlentities received single-quotes around it.

Installing IMAP extension for PHP on Mountain Lion

12 Replies

Based on Dao Hoang Son’s tutorial (itself based on Dan Spencer’s Lion tutorial), as well as a few corrections of my own, I came up with the following script. It fetches and installs University of Washington’s IMAP library, then the PCRE – Perl Compatible Regular Expressions library, and finally the PHP IMAP extension itself.

Please study the script yourself before running it, or run it line by line. It performs no error checking, meaning it might totally wreck your machine — and I’m not responsible if it does. Keep a Time Machine backup around and unplugged from the computer, in case it does.

The script wasn’t yet tested in its complete form; it’s an approximate transcript of commands I ran in shell. But since I’ll keep it around in case I ever need to re-run it, I’m fairly certain it works.

UPDATE December 24th 2012 – Merry Christmas! I’ve applied corrections based on Mehmet’s comment. He also comments you need to install autoconf before running the script (so phpize can work). I already had it installed.

PHP on Mac no longer able to connect to MySQL

Leave a reply

It’s been a while since I did web development on my Mac, and MySQL ceased to work. Could be related to that one time that I accidentally removed a bunch of dot-files from my home directory, could be related to MySQL upgrade. In any case, it no longer worked.
What I figured out was that the /var/mysql/mysql.sock UNIX domain socket was no longer generated. The /var/mysql folder was missing. When just creating it and assigning it to user _mysql (chown _mysql /var/mysql) did not help, I knew something was wrong with configuration.

MySQL tries to read configuration from /etc/my.cnf. To get its UNIX domain socket where PHP expects it, this needs to be contained in this configuration file:

[client]
port = 3306
socket = /var/mysql/mysql.sock


[mysqld]
port = 3306
basedir = /usr/local/mysql/
socket = /var/mysql/mysql.sock
; datadir = /servers/raiddrive/databases/

Please read the manual for details, and this is not administration advice; I’m not sure if this opens security holes, but I only use MySQL for development purposes. (Because you should know better than letting programmers near mission critical production servers.)

Yahoo! OpenID’s XRDS check, Apache2 and PHP

Leave a reply

Another continuation of a previous blogging session 🙂

A reminder, we’re talking about this:

Warning: This website has not confirmed its identity with Yahoo! and might be fraudulent. Do not share any personal information with this website unless you are certain it is legitimate.

PHP+Apache2 users out there might be interested in this reminder, which it’s already mentioned on previous post’s checklist, but I’d like to point it out again.

Don’t name your file xrds.xml.php and try to serve it as xrds.xml while changing Content-type to application/xrds+xml in the header. Apache2 is braindead (or used to be) and doesn’t even attempt to execute the file.

Yahoo! sends an Accept header in its HTTP request, listing application/xrds+xml. Apache decides your file is not of correct filetype, and sends Yahoo! the 406 Not Acceptable response. Referring to same file with the .php extension included makes Apache actually execute the file, and then compare the content-type to the accept header from the client.
