PDO, or PHP Data Objects, provides a more powerful API that doesn't care about the driver you use; it's database agnostic. Further, it offers the ability to use prepared statements, virtually eliminating any worry of SQL injection.

serializeArray already does exactly that. You just need to massage the data into your required format:

$.fn.serializeObject = function()
{
    var o = {};
    var a = this.serializeArray();
    $.each(a, function() {
        if (o[this.name] !== undefined) {
            if (!o[this.name].push) {
                o[this.name] = [o[this.name]];
            }
            o[this.name].push(this.value || '');
        } else {
            o[this.name] = this.value || '';
        }
    });
    return o;
};

Works in Ubuntu based systems.

You should disable them using either systemctl (if you're using systemd) or update-rc.d:

systemctl disable apache2 mysql

or

update-rc.d apache2 disable
update-rc.d mysql disable

Warning! This will REMOVE the service!

sudo update-rc.d -f  apache2 remove
sudo update-rc.d -f  mysql remove

One of my favorite things about Linux is customization. There are many ways to customize it, and the most interesting of them all is the icons. Though they don’t change your entire interface, they can change the way you see your desktop. Icons make you feel at home, and no theme feels quite as complete without them.

How to install icon themes

Icon themes can be installed in two ways. You can install your icons to the system directory, effectively making your icon theme accessible to every user on the system. Alternatively, it’s possible to just enable it for one user only.

Download an icon theme of your choice and extract the files inside the archive. For instance, if you’ve chosen to download Dalisha (see the link below), you’d be extracting “Dalisha_2_2.tar.gz”. Once extracted, a folder will appear (in this case it’s called Dalisha). Open a terminal window and enter the command(s) below to install the icon themes.

Installing systemwide

sudo mv /path/to/icon/theme/folder/ /usr/share/icons/ -r

Installing for one user

mv /path/to/icon/theme/folder/ ~/.icons -r

• Remember to change the filepath to where you have extracted the icon theme archive.

Once the theme has been installed, enable the icon theme inside your desktop environment with the DE’s own configuration tool. Or, using your tool of choice. If you are not sure what tool to use, check out Gnome Tweak Tool (it works with most GTK desktops). If you’re on KDE, just open the KDE application menu and search icons. It should be pretty straight-forward.

Now, check out some of the beautiful icon themes below.
