dotKernel will be a “skeleton”of Zend Framework.
DotKernel borrowed the coding standard from Zend Framework: ZF Coding Standard with some exceptions.

In what follows, we will make remarks only on those features that are slightly different in the coding standards of dotKernel.

B.2. PHP File Formatting

• B.2.2. Indentation

indentation – make indent with tabs, and not with space

B.3. Naming Conventions

Camel naming convention

• B.3.1. Classes

starts with Dot_ (e.g. Dot_Templates)

• B.3.2. Interfaces

ends with the string “Interface”(e.g. Dot_Db_Interface)

• B.3.3. Filenames

classes will have double extension: “.inc.php”
All other php files will have the extension “.php”

B.4.6. Control Statements
every starting curly brace } after a statement starts on a new line, end it’s closing curly brace } will be on a new line too. The start and end braces must be on the same column (for better indentation of the code)
e.g:

if ($a != 2)
{
   $a = 2;
}

if ($a != 2)
{
    $a = 2;
    if($a == 2)
    {
       $c = 3;
    }
}
