General

  • Beginning brackets do NOT linebreak. They start one space after the end parenthesis, as according to traditional Unix policy.
  • Do not do any real logic in object constructors. Create class methods to do so. null, true and false should always be lowercase.
  • Avoid embedded assignments (ex: $d = ($a = $b + $c) is bad).
  • Never use extract().
  • Avoid using global variables if at all possible.
  • Document EVERYTHING.

Parenthesis

  • Do not put parenthesis next to keywords. Put a space between.

  • Do put parenthesis next to function names.

  • Do not use parenthesis in return statements when it's not necessary. Example:``` php if ($test) { } while ($test == $other) { } array_push($one,$two); return $test;

  • Do not use parenthesis when using include, require, include_once, and require_once.

Classes

  • All ''core'' classnames, unless stated otherwise for special conditions, will be prefixed with the "mod" prefix: ie, modChunk, modTemplate, etc.

  • All method names will be camelCase and will start with a lowercase letter.

  • All private methods and variables must be prefixed with the underscore _ character.``` php class modFactor { public $publicVar; private $_privateVar; private function _privateFunc() { } public function publicFunc() { } }

    
    

Variables

Note these are not function arguments.

  • Use all lowercase letters.
  • Separate words with the underscore.

Function Arguments and Class Variables

  • The first letter is lowercase, rest are camelCase. Example:``` php class modFactor { public function testFunc($testVar, array &$anotherTest = array()) { $this->_privateVar = $testVar; $local_variable =& $anotherTest; } }

    
    

Arrays

  • Array index names use the underscore _, not the dash as their separator. This prevents errors with magic_quotes.

  • Array index names are always lowercase. Spaces are represented by an underscore.

  • Array index names are always encapsulated with single quotes. Example:``` php $_lang['chunk_create_text'] = 'Test';

    
    

Constants

  • Constants must be in all UPPERCASE letters.
  • Use only if absolutely necessary.

File Structure

  • Always name PHP class files in name.class.php format.

Prefixing

  • Lexicon strings for Components need to be prefixed:
$_lang['mycomponent.welcome_message'] = 'Welcome!';

  • Always prefix class names; eg: 'finBank', 'finTransaction', etc.
  • Always prefix Chunk names; eg: 'finStatement', 'finDeposit'
