  • Codeigniter 3 and PHP 8.0 / 8.1 Compatibility

    Codeigniter 3.1.12 (and above) now supports PHP 8.0 / 8.1.

    Latest Codeigniter 3 version now is 3.1.13.

    If you use Codeigniter older than 3.1.12, and you use PHP 8.0 / 8.1, then i suggest you to upgrade to the latest Codeigniter 3.

  • Use Mailgun Plain PHP Curl Code

    Mailgun is one of some services to send e-mail. It has a nice PHP library here. But for some reason, it only works in my local server, and it does not work at all in remote server and the code returns “Mailgun server is not reachable” error (although i have tried to disable server firewall, which was not a best decision).

  • How to Install PECL Memcache in WHM / CentOS

    You can run these commands to install PECL memcache (not memcached).
    However, this memcache will work with memcached.

    wget http://pecl.php.net/get/memcache-3.0.8.tgz
tar xvfz memcache-3.0.8.tgz
cd memcache-3.0.8
phpize
./configure
make
make install

    Take note of the php extensions directory that memcache is installed in.
    Mine is: /usr/local/lib/php/extensions/no-debug-non-zts-20020429/

    Then add this line to your php.ini

    extension="/usr/local/lib/php/extensions/no-debug-non-zts-20020429/memcache.so"

  • PHP HtmlEntities for UTF-8 Characters

    If you just use simple PHP htmlentities function with one argument, you will notice that when you pass string that contains UTF-8 characters, the result is incorrect leaving you with some incorrect characters on the result.

    To use it correctly, use this code 🙂

    htmlentities($your_string, ENT_COMPAT, 'UTF-8');

  • Enabling CodeIgniter $_GET

    Here is how to enable CodeIgniter support to $_GET and still able to use the normal “SEO-friendly” URL working together.
    So you will get a URL like this

    http://www.example.com/index.php/the_controller/the_function/?some=thing&more=yes

    First approach is modify your “config.php” and change this line.

    $config['enable_query_strings'] = true;

    But this is not recommended because on pagination, you will get ugly URL.

  • Multilanguage Programming with UTF-8 Encoding

    Multilanguage non-ASCII site? Sometimes we need to make website that can handle languages which contains non-ASCII characters, for example chinese, russian, french, germany, etc.
    To handle this, we need to handle the language on 3 parts : on PHP itself, HTML, and on the database (i use MySQL as example here).
    Basically, we need to adjust the charset (character set) into UTF-8.
