Your programming style

I would like to know what writing style our habracoders use. Naturally, the taste and color, as well as the ways of implementing comrades, are not, but nonetheless. It is no secret that there are a sufficient number of options for designing program code, and it is not necessary to adhere to any of them. Here are some examples that have been found on the Internet:



1) Rational style
This is one of the most common styles since Kernighan and Ritchie, authors of C., used it.

if ($ flag) {
    echo "Hello world!";
}
?>

2)
Almen's style Eric Allman wrote BSD utilities in this style, therefore this style is often called the “BSD style”:

if ($ flag)
{
echo "Hello world!";
}
?>

3) Whitesmith style

if ($ flag)
    {
    echo "Hello world!";
    }
?>

4) GNU Style
The GNU Free Software Foundation programmers use the following braces

if ($ flag)
    {
        echo "Hello world!";
    }
?>

the style that I use

if ($ flag)
{
    echo "Hello, World!";
}
?>

These were some examples of design, and concerning only arrangement of control brackets .
Now the actual question: What method do you use? Maybe you have your own corporate identity? Share with the habrasociety;)
