● http://php.net/archive/2016.php#id2016-12-01-3

Class constant visiblity modifiers<?php class Token {// Constants default to publicconst PUBLIC_CONST = 0; // Constants then also can have a defined visibility private const PRIVATE_CONST = 0; protected const PROTECTED_CONST = 0; public const PUBLIC_CONST_TWO = 0; //Constants can only have one visibility declaration list private const FOO = 1, BAR = 2;}

Square bracket syntax for arraydestructuring assignment

<?php // The two lines in each of the following pairs are equivalent to each other list($a, $b, $c) = array(1, 2, 3);[$a, $b, $c] = [1, 2, 3]; list("a" => $a, "b" => $b, "c" => $c) = array("a" => 1, "b" => 2, "c" => 3);["a" => $a, "b" => $b, "c" => $c] = ["a" => 1, "b" => 2, "c" => 3]; list($a, $b) = array($b, $a);[$a, $b] = [$b, $a];

Allow specifying keys in list()<?php list( CURLOPT_GET => $isGet, CURLOPT_POST => $isPost, CURLOPT_URL => $url) = $curlOptions;$points = [ ["x" => 1, "y" => 2], ["x" => 2, "y" => 1]]; list(list("x" => $x1, "y" => $y1), list("x" => $x2, "y" => $y2)) = $points; $points = [ "first" => [1, 2], "second" => [2, 1]]; list("first" => list($x1, $y1), "second" => list($x2, $y2)) = $points;

Catching Multiple Exception Types

<?php try { // Some code...} catch (ExceptionType1 | ExceptionType2 $e) { // Code to handle the exception} catch (\Exception $e) { // ...}

PHP-FIG

● The FIG stands for FrameworkInteroperability Group. The name untilrecently was “PHP Standards Group” but thiswas somewhat inaccurate of the intentionsof the group

● http://www.php-fig.org/

Accepted PSR

PSR-1: Basic Coding Standard PSR-2: Coding Style Guide PSR-3: Logger Interface PSR-4: Autoloader PSR-6: Caching Interface PSR-7: HTTP message interfaces PSR-13: Link definition interfaces

PSR-4: Autoloader This PSR describes a specification for autoloading

classes from file paths, e.g.– Fully Qualified Class Name

● \Symfony\Core\Request– Namespace Prefix

● Symfony\Core– Base Directory

● ./vendor/Symfony/Core/– Resulting File Path

● ./vendor/Symfony/Core/Request.php

Composer

● Composer is a tool for dependencymanagement in PHP

● It allows you to declare the libraries yourproject depends on and it will manage(install/update) them for you.

● https://getcomposer.org/

Installation php -r "copy('https://getcomposer.org/installer',

'composer-setup.php');" php -r "if (hash_file('SHA384', 'composer-setup.php') ===

'aa96f26c2b67226a324c27919f1eb05f21c248b987e6195cad9690d5c1ff713d53020a02ac8c217dbf90a7eacc9d141d') { echo 'Installer verified'; } else { echo 'Installer corrupt';unlink('composer-setup.php'); } echo PHP_EOL;"

php composer-setup.php php -r "unlink('composer-setup.php');"

composer.json

{ "require": { "monolog/monolog": "1.0.*" }}

Basic usage

composer install composer update

Autoloading For libraries that specify autoload information,

Composer generates a vendor/autoload.php file. Youcan simply include this file and you will get autoloadingfor free– require __DIR__ . '/vendor/autoload.php';– $log = new Monolog\Logger('name');– $log->pushHandler(new

Monolog\Handler\StreamHandler('app.log',Monolog\Logger::WARNING));

– $log->addWarning('Foo'); Composer also support PSR-4 autoloading
