PSR-1: Basic Coding Standard
1. Overview
Files MUST use only <?php and <?= tags.
Files MUST use only UTF-8 without BOM for PHP code.
Files SHOULD either declare symbols (classes, functions,
constants, etc.) or cause side-effects (e.g. generate output, change
.ini settings, etc.) but SHOULD NOT do both.
Namespaces and classes MUST follow an "autoloading" PSR:
[PSR-0, PSR-4].
Class names MUST be declared in StudlyCaps.
Class constants MUST be declared in all upper case with underscore
separators.
Method names MUST be declared in camelCase. 4

<?php
// side effect: change ini settings
ini_set('error_reporting', E_ALL);
// side effect: loads a file
include "file.php";
// side effect: generates output
echo "<html>\n";
// declaration
function foo()
{
// function body
}
<?php
// declaration
function foo()
{
// function body
}
// conditional declaration is *not* a side
effect
if (! function_exists('bar')) {
function bar()
{
// function body
}
}
