 Structure
 ---------
 
-* Never use short tags (`<?`);
-
-* Don't end class files with the usual `?>` closing tag;
-
-* Indentation is done by steps of four spaces (tabs are never allowed);
-
-* Use the linefeed character (`0x0A`) to end lines;
-
 * Add a single space after each comma delimiter;
 
-* Don't put spaces after an opening parenthesis and before a closing one;
-
 * Add a single space around operators (`==`, `&&`, ...);
 
-* Add a single space before the opening parenthesis of a control keyword
-  (`if`, `else`, `for`, `while`, ...);
-
 * Add a blank line before `return` statements, unless the return is alone
   inside a statement-group (like an `if` statement);
 
-* Don't add trailing spaces at the end of lines;
-
 * Use braces to indicate control structure body regardless of the number of
   statements it contains;
 
-* Put braces on their own line for classes, methods, and functions
-  declaration;
-
-* Separate the conditional statements (`if`, `else`, ...) and the opening
-  brace with a single space and no blank line;
-
 * Declare visibility explicitly for class, methods, and properties (usage of
   `var` is prohibited);
 
-* Use lowercase PHP native typed constants: `false`, `true`, and `null`. The
-  same goes for `array()`;
-
-* Use uppercase strings for constants with words separated with underscores;
-
 * Define one class per file - this does not apply to private helper classes
   that are not intended to be instantiated from the outside and thus are not
   concerned by the PSR-0 standard;
