DEVELOPMENT PRACTICES
1. Coding standards
• Readable code
• Easy to maintain
• Documentation
<?
// Method 1 if($condition)function1($a, $b, $c);if($i < 7 && $j > 8 || $k == 4)a($i);
?>
<?php
// Method 2 if ($condition) {
getUser($id, $username, $key); }
If (($i < 7) && (($j < 8) || ($k == 4))) {
displayGraph($value); }
• PEAR Coding Standardshttp://pear.php.net/manual/en/standards.php
• Zend Framework Coding Standardshttp://framework.zend.com/manual/en/coding-standard.html
• eZ Components Implementation guidelineshttp://www.ezcomponents.org/contributing/coding_standards
2. Code Commenting
• Reduced code understanding time
• Serves as a documentation
• Answer the question: WHY??
/**
* Add number

* This function will take two integer numbers and will
* return the addition result of them.
*
* @param int first number
* @param int second number
* @return int addition result
*/
function addNumbers($firstNum, $secondNum)
3. Code re-use
