File and Directory Names
1. CamelCased should not be used. 2. Should be lowercase. Example: Incorrect ThisIsDirectory/ThisIsDirectory/ThisIsFile.php Correct this_is_directory/this_is_directory/this_is_file.php

Coding Standards
In order to produce highly consistent source code, we ask that everyone follow the coding standards as closely as possible.

Brackets
Please use BSD/Allman Style bracketing. Example: while (x == y) { something(); somethingelse(); }

The following is still syntactically correct:
//while (x == y) { something(); somethingelse(); }

As is this:
//for (int i=0; i < x; i++) //while (x == y) if (x == y) { something(); somethingelse(); }

Curly Brackets
Curly brackets are placed on their own line, indented to the same level as the control statement.
// Correct if ($a === $b) { ... } else { ... } // Incorrect if ($a === $b) { ... } else { ... }

Class Brackets
The only exception to the curly bracket rule is, the opening bracket of a class goes on the same line.
// Correct class Foo { // Incorrect class Foo {

Empty Brackets
Don't put any characters inside empty brackets.
// Correct class Foo {} // Incorrect class Foo { }

Array Brackets
Arrays may be signle line or multi-line array('a' => 'b', 'c' => 'd') array( 'a' => 'b',

'c' => 'd', )

Opening Parenthesis The opening array
