old coding standart

Pixelpost 2.0 Coding Standards

• KISS (Keep It Simple, Stupid)
• Add PHPDoc formatted comments to all functions, constants, etc.
• Function and methods names should be all lowercase and use underscores to separate words e.g. my\_public\_method().
• Curly brackets should be placed on the line below the statement.
• Code should be properly indented using tabs not spaces.
• Add a space after all if, while, and for statements.
• Add a space after function parameters e.g. my\_function($param1, $param2)
• Files will be saved in UTF-8 format using *NIX style linefeeds e.g. \n.
• No shorthand PHP tags <? ?>.
• Constants should be all caps with underscores separating words e.g. MY_CONSTANT.
• No closing PHP tag ?> at the end of PHP documents.
• Private & Protected methods should have an underscore prefix e.g. \_my\_private\_method().
• Use single quotes ' for strings, only use double quotes " when necessary.

Sample Code

Below is is a sample function with proper formatting and comments, as well as some code using the defined function.

<?php

/**
 * Verify if the specified filename has one of the defined file extensions.
 *
 * @since Version 2.0 (Alpha 1)
 * 
 * @param string $filename the name of the file
 * @param string|array $extension the extension(s) to verify against
 *
 * @return bool
 *
 */
function has_extension($filename, $extension)
{
	$file_extension = substr($filename, strrpos($filename, '.'));

	if (is_array($extension))
	{
		return (in_array($file_extension,$extension)) ? true : false;
	}
	else
	{
		return ($file_extension == $extension) ? true : false;
	}
}

/** 
 * Example Usage:
 * @todo combine if statements
 */	
if ($handle = opendir($dir))
{
	while (false !== ($file = readdir($handle)))
	{
		if ($file != '.' && $file != '..')
		{
			if (is_file($file) && has_extension($file, array('.php', '.html')))
			{
				var_dump($file);
			}
		}
	}
	closedir($handle);
}
