PHP Style Guide

All rules and guidelines in this document apply to PHP files unless otherwise noted. References to PHP/HTML files can be interpreted as files that primarily contain HTML, but use PHP for templating purposes.

The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.

Most sections are broken up into two parts:

Overview of all rules with a quick example
Each rule called out with examples of do's and don'ts

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)

	<?php

	$url = 'http://google.com';

	if ($argc > 1){
	$url = $argv[1];
	}

	$ch=curl_init();
	// user credencial

	<?php

	/**
	* [list_searcheable_acf list all the custom fields we want to include in our search query]
	* @return [array] [list of custom fields]
	*/
	function list_searcheable_acf(){
	$list_searcheable_acf = array("title", "sub_title", "excerpt_short", "excerpt_long", "xyz", "myACF");
	return $list_searcheable_acf;
	}

	/*

	SET NAMES utf8;
	SET sql_mode = 'NO_AUTO_VALUE_ON_ZERO';

	DROP TABLE IF EXISTS postcodes_geo;
