Class constant visiblity modifiers
<?php
class Token {
// Constants default to public
const 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 array
destructuring 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 Framework
Interoperability Group. The name until
recently was “PHP Standards Group” but this
was somewhat inaccurate of the intentions
of 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
●
SymfonyCoreRequest
– Namespace Prefix
●
SymfonyCore
– Base Directory
●
./vendor/Symfony/Core/
– Resulting File Path
●
./vendor/Symfony/Core/Request.php

Composer
●
Composer is a tool for dependency
management in PHP
●
It allows you to declare the libraries your
project 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') ===
'aa96f26c2b67226a324c27919f1eb05f21c248b987e6195c
ad9690d5c1ff713d53020a02ac8c217dbf90a7eacc9d141d'
) { 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. You
can simply include this file and you will get autoloading
for free
– require __DIR__ . '/vendor/autoload.php';
– $log = new MonologLogger('name');
– $log->pushHandler(new
MonologHandlerStreamHandler('app.log',
MonologLogger::WARNING));
– $log->addWarning('Foo');

Composer also support PSR-4 autoloading
